优化空间结构

在我国，战略规划作为一种“非法定规划”，是一种对城市与区域宏观战略性核心问题的研究，可以对从总体规划到详细规划在宏观性、灵活性和战略性等方面的不足给予修正和补充。从规划内容上来看，战略规划的重点包括空间发展方向、城乡空间结构、区域与城市发展模式、产业选择与功能定位以及景观特色等方面。从规划方法上来看，其技术核心为区域分析、产业研究、空间结构、支撑系统和生态保障等。从规划目标上来看，战略规划的定位是通过宏观、粗线条的战略研究，来把握城市未来发展大的趋势、方向、动态和结构。可见，研究城市空间发展的规律性和合理性是战略规划的核心和前提。

空间基因理论与技术在城市空间发展的结构、形态等发展规律和城市形态组织方式的建构方面对空间战略规划具有重要作用，能够寻求适合城市可持续发展目标的形态，为城市规划中的空间发展形态与整体结构布局提供依据和参考。空间基因技术的引入能够完善和修正规划中的价值标准和目标取向；同时，空间基因对空间发展规律的总结和发展模式的理论探索，为战略规划提供了一个对比和借鉴的参考系。团队在天津、深圳、南京等城市的空间战略规划实践中，对空间基因技术在城市空间发展战略规划中的应用进行了探索。□

In China, strategic planning, as a kind of ＂non-statutory planning＂, is a kind of research on the macro-strategic core issues of cities and regions, which can correct and supplement the deficiencies in macroscopic aspect, strategic aspect and flexibility from the comprehensive planning to the detailed planning.From the perspective of planning content, the focus of strategic planning includes the direction of spatial development, urban and rural spatial structure, regional and urban developing mode, industrial selection and functional positioning, and landscape characteristics.From the perspective of planning methods, its technical core is regional analysis, industrial research, spatial structure, support system and ecological protection.From the perspective of planning objectives, the orientation of strategic planning is to grasp the general trend, direction, dynamics and structure of the future development of the city through macro and broad strategic research.It can be seen that the study of the regularity and rationality of urban spatial development is the core and premise of strategic planning.

The space gene theory plays an important role in spatial strategic planning in terms of the developinglaw of urban spatial development, such as structure and form, and the construction of organisation mode of urban form, which can seek the form suitable for the goal of urban sustainable development and provide the basis and reference for the spatial developing form and the comprehensive structural layout in urban planning.The introduction of the space gene could improve and modify the value standard and target orientation in planning.Moreover, the summary of spatial developing law and the theoretical exploration of developing model of the space gene provide a comparative and referential frame for strategic planning.In the practice of spatial strategic planning in Tianjin, Shenzhen, and Nanjing, the application of the space gene is explored.□
