【摘要】：伴随着深圳快速城市化进程，城市出现了更加明显的扩散特征，应该说，无论在量上还是质上，空间结构变化最大，土地利用模式转变最快的都是城市外围地区，它作为典型的半城市化空间，受到城市内部空间重组和外部空间扩展的影响，是城市发展最敏感的区域，研究深圳城市空间结构对外围地区的作用、外围地区空间演变过程、特征与模式，对于研究城镇空间优化、外围地区的演变机制和发展都有重要意义。论文主要分三个部分，第一部分提出城市外围地区的概念，界定深圳城市外围地区范围和分析城镇空间演变。首先从城市空间结构和城市化特征的角度提出城市外围地区的概念；然后在分析深圳城市内部空间演变的基础上阐明其内部地域结构模式为“放射圈层式”，以此来界定深圳外围地区的范围，并解析城市内部空间重组和外部空间扩展对外围地区用地的影响，及外围地区用地构成、特征和存在的问题；最后以深圳外围地区的茅洲河流域为例，利用LUCC技术，详细剖析流域城镇外部空间扩展和内部空间重组过程及阶段性特征，总结出流域城镇以聚集型空间扩展方式为主，再通过廊道相连填充，最终形成“集中带状”的空间演化模式，，并提出“双核三轴”的空间结构模式来促进流域的平衡发展。第二部分提出外围地区基于网格的空间优化方法，并对空间优化进行实证分析。首先以网格为基本单元，利用GIS技术将可量化的指标进行加权计算，生成茅洲河流域模拟空间，通过对比剖析模拟空间对未来的发展启示；然后对流域整体空间和内部空间进行规则式网格划分，形成整体网格和内部网格，引入绿道作为介质生成新的空间体系，阐明绿道介入网格单元的整体空间和内部空间优化策略；最后对绿道介入城镇空间优化进行实证分析，主要包括外围地区区域绿道、城市绿道和社区绿道作为连接、隔离和缓冲的空间优化，以及绿道介入的多功能空间营造和发展契机，并通过问卷调查分析茅洲河流域绿道建设的实际效应。第三部分主要论述深圳外围地区空间演变机制与大城市外围地区规划管理。首先剖析深圳外围地区空间演变的动力机制，提出制度主导下的城市经济发展、社会空间变革和重大事件相互作用构成了外围地区空间演变的综合机制；然后阐明综合机制作用下，深圳外围地区产业、功能、生态和文化的发展方向及“差异化组团式”的空间发展模式；最后研究国内外城市外围地区规划管理策略，提出大城市外围地区的规划管理应做到规划理念上时空适应、规划编制上全程动态和规划管理上时序创新。
[Abstract]:With the rapid urbanization of Shenzhen, the city has a more obvious diffusion characteristics, it should be said, whether in terms of quantity or quality, the largest change in the spatial structure. As a typical semi-urbanized space, it is the most sensitive area of urban development, which is affected by the reorganization of urban interior space and the expansion of external space. It is of great significance to study the effect of Shenzhen urban spatial structure on the peripheral areas, the spatial evolution process, characteristics and models of the peripheral areas for the study of the urban spatial optimization, the evolution mechanism and the development of the peripheral areas. The paper is divided into three parts. The first part puts forward the concept of the periphery of the city. Firstly, the concept of urban periphery area is put forward from the perspective of urban spatial structure and urbanization characteristics. Then, on the basis of analyzing the evolution of the inner space of Shenzhen city, it is clarified that the internal regional structure model is "radiation circle type", so as to define the scope of the peripheral area of Shenzhen. It also analyzes the influence of urban interior space reorganization and outer space expansion on the land use in peripheral areas, and the composition, characteristics and existing problems of land use in peripheral areas. Finally, taking the Maozhou River basin in the peripheral area of Shenzhen as an example, using LUCC technology, the process and stage characteristics of outer spatial expansion and internal spatial reorganization of urban areas in the basin are analyzed in detail. Summing up that the main way of urban agglomeration space expansion, and then through the corridor connected to fill, and finally form a "centralized belt" spatial evolution model. The spatial structure model of "double core and three axes" is put forward to promote the balanced development of the watershed. In the second part, a mesh-based spatial optimization method in peripheral areas is proposed, and an empirical analysis of spatial optimization is carried out. Firstly, using the grid as the basic unit, the quantifiable indexes are weighted by using GIS technology. The simulation space of Maozhou River Basin is generated, and the enlightenment of simulation space to the future development is analyzed. Then the whole space and the internal space of the basin are divided into regular grid to form the whole grid and the internal grid, and the green road is introduced as the medium to generate a new space system. The optimization strategy of the whole space and the interior space of the green road interventional grid cell is expounded. Finally, the paper makes an empirical analysis on the intervention of green roads into urban space optimization, mainly including regional green roads in peripheral areas, urban green roads and community green roads as links, isolation and buffer space optimization. The paper also analyzes the practical effect of green road construction in Maozhou river basin by questionnaire survey, as well as the opportunity of multi-function space construction and development of green road intervention. The third part mainly discusses the spatial evolution mechanism and planning management of the peripheral areas of Shenzhen. Firstly, it analyzes the dynamic mechanism of the spatial evolution in the peripheral areas of Shenzhen, and puts forward the urban economic development under the guidance of the system. The interaction of social spatial changes and major events constitutes the comprehensive mechanism of spatial evolution in peripheral areas. Then, it expounds the development direction of industry, function, ecology and culture in the peripheral areas of Shenzhen under the action of comprehensive mechanism and the spatial development mode of "differentiated group type". Finally, this paper studies the strategies of planning and management in the peripheral areas of cities at home and abroad, and points out that the planning management of the peripheral areas of big cities should adapt to the concept of planning in time and space, dynamic in the whole course of planning and innovation in the timing of planning and management.
