绿水及其研究进展
程国栋,赵文智
被引频次:72
摘要:从水循环的角度分析,全球尺度上总降水的65%通过森林、草地、湿地和雨养农田的蒸散返回到大气中,成为绿水流(绿水),仅有35%的降水储存于河流、湖泊以及含水层中,成为蓝水。目前的水资源评价多集中于可见的、可以被人类直接利用的蓝水资源,忽略了绿水资源的评价和管理。绿水最初被定义为蒸散流,是流向大气圈的水汽流,后来被定义为具体的资源,即绿水是源于降水、存储于土壤并通过植被蒸散发消耗掉的水资源,尤其在雨养农业区是重要的水资源。介绍了绿水的概念,绿水在陆地生态系统中的作用,综述了绿水评价研究的进展、影响绿水流的因素、全球绿水资源状况和水安全等,展望了未来绿水研究,指出应将绿水资源纳入水资源评价之中,开展绿水管理、绿水和蓝水综合利用研究,自然生态系统与粮食生产绿水均衡利用研究。

Abstract: Urbanization of a watershed degrades both theform and the function of the downstream aquatic system,causing c hanges t hat can oc cur r apidly a nd are very difficult to avoid or correct. A variety of physical data from lowland streams in western Washington displays the onset of r eadily o bservable aq uatic-system degradation a t a remarkably consistent l evel of development, typically about ten percent effective impervious area in a watershed. Even lower levels of urban development cause significant degradation in sensitive water bodies and a reduced, but less w ell qu antified, level o f f unction throughout the system as a whole. Unfortunately, established methods of mitigating the downstream impacts of urban development may h ave only lim ited e ffectiveness.

Without a better understanding of the critical processes that lead t o degradation, s ome downstream aquatic-system damage is probably inevitable without limiting the extent of watershed development itself.

Threats to the running water ecosystems of the world
Malmqvist, B; Rundle, S
被引频次:344
Abstract: Running waters are perhaps the most impacted ecosystem on t he planet as they have been the focus for human s ettlement a nd a re he avily e xploited f or w ater supplies, irrigation, electricity generation, and waste disposal. Lotic systems also have an intimate contact with their catchments and so land-use alterations affect them directly. H ere l ong-term trends i n t he factors t hat currently i mpact r unning w aters are r eviewed w ith the aim of predicting what the main threats to rivers will be in the year 2025. The main ultimate factors forcing change in running waters (ecosystem destruction, physical habitat and water chemistry alteration, and the direct addition or removal of species) stem from proximate influences from urbanization, industry, land-use change and water-course alterations. A ny one r iver i s li kely t o be s ubjected to several types of impact, and the management of impacts on lotic systems is complicated by numerous links between di fferent f orms of a nthropogenic e ffect. L ongterm trends for different impacts vary. Concentrations of chemical pollut ants s uch a s t oxins a nd nut rients ha ve increased in rivers in developed countries over the past century, with recent reductions for some pollutants (e.g. metals, or ganic t oxicants, acidification), a nd c ontinued increases in others (e.g. nutrients); there are no long-term chemical data for developing countries. Dam construction increased rapidly during the twentieth century, peaking in the 1970s, a nd t he nu mber of r eservoirs ha s s tabilized since t his t ime, w hereas the t ransfer o f ex otic s pecies between lotic systems continues to increase. Hence, there have been some success stories in the attempts to reduce the im pacts f rom a nthropogenic im pacts i n de veloped nations. Improvements in the pH status of running waters should c ontinue w ith l ower s ulphurous e missions,although emissions of nitrous oxides are set to continue under current legislation and will continue to contribute to acidification and nutrient loadings. Climate change also will im pact r unning w aters t hrough a lterations i n hydrology a nd t hermal r egimes, although pr ecise predictions a re pr oblematic; e ffects a re likely t o va ry between r egions a nd t o ope rate alongside r ather than override those from other impacts. Effects from climate change may be more extreme over longer time scales (>50 years). T he ove rriding pr essure on running water ecosystems u p t o 202 5 w ill s tem f rom t he pr edicted increase in the hum an p opulation, w ith c oncomitant increases in urban de velopment, i ndustry, a gricultural activities and water abstraction, diversion and damming. Future degradation could be substantial and rapid (c. 10 years) and will be concentrated in those areas of the world where r esources f or c onservation a re most lim ited a nd knowledge of lotic ecosystems most incomplete; damage will cen tre o n l owland r ivers, w hich ar e al so r elatively poorly s tudied. C hanges in management pr actices a nd public a wareness do a ppear t o be be nefiting r unning water e cosystems in developed c ountries, a nd could underpin conservation strategies in developing countries if they were implemented in a relevant way.

Low impact development practices: A review of current research and recommendations for future directions
Dietz, Michael E
被引频次:175
Abstract: The low impact development (LID) approach has be en r ecommended a s a n a lternative t o traditional stormwater design. Research on individual LID practices such a s bi oretention, pe rvious pa vements, a nd gr assed swales h as increased i n r ecent years. Bioretention ce lls have been effective in retaining large volumes of runoff and pol lutants on site, a nd c onsistently r educed concentrations of c ertain pol lutants s uch a s metals. However, r etention of certain pol lutants s uch as nitrate-nitrogen a nd phosphorus has be en pr oblematic. Porous pavements have been extremely effective in infiltrating stormwater runoff. Concerns have been raised about groundwater contamination, but research has shown that this is not a problem in most settings. Green roofs have been found to retain a l arge percentage of rainfall (63% o n av erage) i n a v ariety o f cl imates. A co mmon thread across bioretention, green roofs and grassed swales was found: the export of phosphorus. The issue appears to be linked to high phosphorus levels in the soil media, or possibly to fertilization of turf or planted areas. Solutions to t his pr oblem ha ve be en r ecommended. C ontrary to popular belief, research has shown that bioretention and pervious pavements continue to infiltrate even with frost in the ground. Although issues have been identified with retention of certain pollutants, the LID approach has been found to result in increased retention of stormwater and pollutants on site, mimicking pre-development hydrologic function. Future research needs have also been identified.

Pretreatment for low pressure membranes in water treatment: A review
H Huang; K Schwab; JG Jacangelo
被引频次:150
Abstract: The a pplication of l ow pr essure membranes(LPMs) to drinking water treatment and wastewater reuse has undergone accelerated development in the past decade. Integration of pretreatment with LPM filtration has been widely employed at full scale to reduce membrane fouling and/or increase the removal of certain aquatic contaminants. In principle, pretreatment of source water can i mpact membrane f iltration i n t hree w ays: a ltering contaminant size distributions, changing mutual affinities of contaminants or their affinities to membrane surfaces,and suppressing undesirable microbial growth or removing biodegradable c ontaminants. T he lit erature s hows t hat,compared to t he w ell-demonstrated e nhancement of contaminant removal, impact of pretreatment to membrane fouling is often small or even negative, which is further complicated by va riations i n s ource w ater qua lity a nd membrane pr operties. Coagulation ha s been t he most successful pretreatment for fouling reduction. Novel technologies are in immediate need for fouling control; ones which rely on a better understanding of the mechanisms of p retreatment a nd L PM filtration a re warranted. T his article provides a critical review of the state-of-the-art of pretreatment for LPMs, and discusses potential areas for future technical development and scientific studies.

Improving agricultural water productivity: Between optimism and caution

被引频次:134
Abstract: In its broadest sense, water productivity (WP) is the n et r eturn fo r a u nit o f w ater u sed. Im provement o f water productivity aims at producing more food, income,better livelihoods and ecosystem services with less water. There i s co nsiderable s cope f or i mproving water productivity of crop, livestock and fisheries at field through to basin scale. Practices used to achieve this include water harvesting, supplemental i rrigation, d eficit irrigation,precision irrigation techniques and soil-water conservation practices. Practices not directly related to water management impact w ater p roductivity b ecause o f interactive effects such as those derived from improvements i n s oil fertility, pest a nd disease c ontrol,crop selection or access to better markets. However, there are several reasons to be cautious about the scope and ease of a chieving water p roductivity g ains. Crop w ater productivity is a lready qu ite h igh in h ighly pr oductiveregions, and gains in yield (per unit of land area) do no t necessarily translate into gains in water productivity. Reuse of water that takes place within an irrigated area or a basin can compensate for the perceived losses at the field-scale in terms of w ater qu antity, though the w ater qu ality is likely to be affected. While crop breeding has played an important role in increasing water productivity in the past,especially by improving the harvest index, such large gains are n ot easily foreseen i n t he future. M ore im portantly,enabling conditions for farmers and water managers are not in p lace to enhance w ater pr oductivity. Improving w ater productivity w ill thus r equire a n und erstanding of the biophysical as w ell as t he s ocioeconomic e nvironments crossing s cales be tween f ield, farm and b asin. P riority areas where substantive increases in water productivity are possible include: (i) areas where poverty is high and water productivity is l ow, (ii) a reas of ph ysical w ater scarcity where competition for water is high, (iii) areas with little water r esources d evelopment w here h igh returns f rom a little extra water use can make a big difference, and (iv)areas o f w ater-driven ecosystem degradation, s uch a s falling groundwater tables, and river desiccation. However,achieving these gains will be challenging at least, and will require s trategies that c onsider c omplex b iophysical a nd socioeconomic factors.

Sink or Swim? Water security for growth and development
Grey, David; Sadoff, Claudia, W
被引频次:113
Abstract: Achieving basic water security, both harnessing the p roductive p otential o f w ater a nd limiting its destructive impact, has always been a societal priority. To capture this duality, water security is defined here as the availability of an acceptable quantity and quality of water for health, livelihoods, ecosystems and production, coupled with an acceptable level of water-related risks to people,environments and economies. This paper looks broadly at those countries that have achieved water security, the paths they chose and the costs they paid, and those countries that have not achieved water security and how this constrains economies and societies. It defines three typologies: countries that have harnessed hydrology, those hampered by hydrology and those that are hostage to hydrology. It finds t hat countries r emaining hostage t o hydrology a re typically among the world’s poorest. They face “difficult”hydrologies of ten characterized b y high inter- and intra-annual rainfall and runoff variability, where the level of institutional and infrastructure investment needed is very high and the ability to invest is low. This paper seeks to capture the d ynamics o f ac hieving w ater security in a hypothetical water and growth “S-curve”, which illustrates how a m inimum p latform o f i nvestments i n water institutions and infrastructure can produce a tipping point beyond w hich w ater makes a n increasingly pos itive contribution to growth and how that tipping point will vary in different c ircumstances. As t here ar e i nevitable trade-offs, achieving water security is never without social and environmental co sts; i n s ome co untries t hese ar e significant, often unforeseen and even unacceptable. This brief analysis suggests that the only historically demonstrated p ath to a chieving w ater security a t the national level has been through investment in an evolving balance of c omplementary institutions a nd infrastructure,but that lessons exist for following this basic path in more sustainable and balanced ways. Insights are provided for balancing a nd s equencing i nvestments, a dapting t o changing v alues and pr iorities, and pu shing down the social and environmental costs. The paper concludes that most w ater-insecure c ountries t oday face f ar greater challenges than those that achieved water security in the last c entury an d ar e w ealthy countries today. T hey f ace more difficult hydrologies and a greater understanding of and therefore g reater r esponsibility f or, the s ocial a nd environment trade-offs inherent in water management. As the costs of poor countries not achieving water security, in terms of hu man suffering, s ustained pove rty, c onstrained growth and social unrest, would be very high, achieving water security is a challenge that must be recognized and must be met.

A review of models for low impact urban stormwater drainage
Elliott, A. H.; Trowsdale, S. A.
被引频次:109
Abstract: Low-impact d evelopment ur ban stormwaterdrainage systems (LID) are an increasingly popular method to reduce the adverse hydrologic and water quality effects of ur banisation. I n this r eview, ten existing s tormwater models are compared in r elation to a ttributes r elevant to modelling LID. The models are all based on conventional methods for runoff generation and routing, but half of the models add a groundwater/baseflow c omponent a nd several include infiltration from LID devices. The models also use conventional methods for contaminant generation and treatment such as buildup-washoff conceptual models and first order decay processes, although some models add treatment mechanisms specific to particular types of LID device. S everal m odels are c apable of m odelling distributed on-site devices with a fine temporal resolution and continuous simulation, yet the need for such temporal and spatial detail needs to be established. There is a trend towards i ncorporation of m ore ty pes of L ID i nto stormwater models, and some recent models incorporate a wide r ange o f LID d evices o r measures. D espite this progress, t here are m any a reas for further m odel development, many of which relate to stormwater models in general, including: broadening the range of contaminants;improving the r epresentation of c ontaminant transport in streams and w ithin treatment d evices; treating b aseflow components a nd r unoff f rom p ervious s urfaces more thoroughly; linkage to habitat and toxicity models; linkage to automated calibration and prediction uncertainty models;investigating up-scaling f or representation of on-site devices at a catchment level; and catchment scale testing of model predictions.

Non-conventional water resources and opportunities for water augmentation to achieve food security in water scarce countries

被引频次:101
Abstract: Given c urrent demographic t rends a nd f uture growth pr ojections, as much a s 60% of the g lobal population may suffer water scarcity by the year 2025. The water-use efficiency techniques us ed w ith c onventional resources h ave b een improved. H owever, w ater-scarce countries w ill ha ve t o rely m ore on t he use of non-conventional water resources to partly alleviate water scarcity. N on-conventional water r esources a re e ither generated a s a pr oduct of s pecialized pr ocesses such as desalination o r ne ed s uitable pr e-use treatment a nd/or appropriate s oil-water-crop m anagement s trategies w hen used f or irrigation. I n w ater-scarce e nvironments, s uch water r esources are a ccessed through the d esalination of seawater and highly brackish groundwater, the harvesting of r ainwater, and the us e of marginal-quality w ater resources for irrigation. The marginal-quality waters used for irrigation consist of wastewater, agricultural drainage water, and groundwater containing different types of salts. in many de veloping c ountries, a major part o f thewastewater g enerated b y domestic, co mmercial, an d industrial sectors is used for crop production in a n untreated or partly treated form. The protection of public health an d t he en vironment ar e t he m ain co ncerns associated with uncontrolled wastewater irrigation. The use of saline and/or sodic drainage water and groundwater for agriculture i s ex pected t o i ncrease. This warrants modifications in t he existing soil, i rrigation, and c rop management pr actices u sed, in or der to cope w ith the increases in s alinity and sodicity that w ill o ccur. I t is evident that w ater-scarce countries ar e not ab le t o m eet their f ood r equirements u sing the conventional and non-conventional w ater r esources available w ithin their boundaries. Another option that may help to achieve food security in these countries is the ‘physical’ transportation of water a nd f ood it ems a cross basins, c ountries, and regions. Long-distance movement of surface freshwater or groundwater and t ransporting t he water i nland via la rge pipelines or ac ross t he sea i n ex tremely l arge bags ar e examples o f ‘physical’ transportation. M ost i nterregional water t ransportation projects a re s till i n t heir i nfancy,though the trade of food items between countries has been going on since international trade began. Although food is imported in the international food trade, the water used to produce the food that is imported into water-scarce countries i s equivalent t o l arge water s avings for t hose countries: without the imports, almost the same amount of water would be needed to produce that food domestically. The t erm ‘virtual w ater’ has been used t o i llustrate t he important role that water plays in the trade in food between countries w ith a w ater surplus and t hose w ith a w ater deficit, which must rely in part on importing food to ensure food security. Because the major food-exporting countries subsidize their agricultural pr oduction s ystems, f oodimporting countries need to consider both the policies and political situations of food-exporting countries, while simultaneously using food trade as a strategic instrument to overcome w ater s carcity and f ood d eficits. This p aper reviews the literature and issues associated with the use of non-conventional w ater r esources and oppor tunities for achieving food security in water-scarce countries.

The most commonly used desalination technologies a re r everse o smosis (RO) and thermal processes such as multi-stage flash (MSF) and multi-effect distillation (MED). In Europe, reverse osmosis, due to its lower e nergy consumption h as g ained much w ider acceptance t han its t hermal alternatives. T his review summarises the current state-of-the art of reverse osmosis desalination, d ealing no t on ly w ith the r everse os mosis stage, but with the entire process from raw water intake to post treatment of product water. The discussion of process fundamentals, membranes and membrane modules and of current and future developments in membrane technology is a ccompanied b y an a nalysis of op erational issues a s fouling and scaling and of measures for their prevention such as adequate cleaning procedures and antiscalant use. Special focus is placed on pre-treatment of raw water and post-treatment of brine as well as of product water to meet drinking and irrigation water standards, including evaluation of current boron removal options. Energy requirements of reverse osmosis plants as well as currently applied energy recovery systems for r eduction of energy consumption are described and cost and cost structure of reverse osmosis desalination are outlined.
