【摘要】：城市绿地生态网络是解决快速城市化进程所带来的生境破碎化问题，，确保城市生态安全的有效途径。选择城市绿地生态网络作为研究对象，旨在探索土地资源供给受限，资源保护与利用需协调并重的双向需求下，资源保护从传统被动适应向积极主动防御方式转变的新思潮下，如何合理构建一个可控制并引导城市合理发展的多层次、多目标的生态网络框架以满足综合要求。 Green infrastructure accessment（GIA）作为这种新思潮的产物，是将提高保护效率作为指导理念的绿色基础设施规划的核心技术手段，它将保护生物学、景观生态学融入到规划领域，在规划尺度、弹性控制、协调引导、连通衔接等方面具有显著的综合优势，成为构建弹性化效率化的综合型绿地生态网络的基本技术平台。运用GIA作为技术方法体系，在深圳市域层面进行网络构建，在解决深圳市现状绿地生态系统存在问题的同时，也可以调整优化技术方法本身。通过地理信息系统平台，实现多源数据的有效整合与空间分析，生成可查询可量化的绿地生态网络数据信息，主要包括三个层级：通过生态要素的识别构建的网络化完整的绿地生态网络；通过生态重要性评价的多层级弹性化的绿地生态网络以及纳入人文游憩因子后实现的多目标综合化绿地生态网络。在此基础之上与深圳市现状绿地生态系统进行比对分析，提出具有实际应用价值的网络构建策略，包括对整体景观格局连通性的优化、划分网络保护优先等级以及如何合理挖掘绿地生态空间内部资源的潜在价值，以提高有限生态资源的保护效率。本研究对我国城市绿地生态网络的构建研究既具有学科交叉融合、方法优化调整方面的理论意义，又具有验证方法可行性从而为其他城市构建合理的生态网络提供范本的实践意义。
[Abstract]:Urban green space ecological network is an effective way to solve the problem of habitat fragmentation caused by rapid urbanization and ensure urban ecological security. This paper chooses urban green space ecological network as the research object, in order to explore the new trend of thought of resource protection changing from traditional passive adaptation to active defense under the two-way demand of limited supply of land resources, coordination of resource protection and utilization. How to reasonably construct a multi-level and multi-objective ecological network framework that can control and guide the rational development of the city to meet the comprehensive requirements of. Green infrastructure accessment (GIA) as the product of this new trend of thought, It integrates conservation biology and landscape ecology into the field of planning, in the planning scale, flexible control, coordination and guidance, it is the core technical means of green infrastructure planning, which takes the improvement of conservation efficiency as the guiding principle, and it integrates conservation biology and landscape ecology into the field of planning. Connectivity has obvious comprehensive advantages and becomes the basic technology platform for the construction of elastic and efficient integrated green space ecological network. Using GIA as the technical method system and constructing the network at the domain level of Shenzhen City, the existing problems of the present green space ecosystem in Shenzhen can be solved, and the optimization technology method itself can be adjusted at the same time. Through the GIS platform, the effective integration and spatial analysis of multi-source data are realized, and the quantifiable data information of greenbelt ecological network is generated. It mainly includes three levels: the whole green space ecological network is constructed through the identification of ecological elements; Through the ecological importance evaluation of the multi-level elastic green ecological network and the human recreation factor after the realization of the multi-objective comprehensive green space ecological network. Based on the comparison and analysis with the present green space ecosystem in Shenzhen City, a network construction strategy with practical application value is put forward, including the optimization of the connectivity of the overall landscape pattern. In order to improve the protection efficiency of limited ecological resources, the priority grade of network protection is divided and the potential value of the internal resources of green space is reasonably excavated in order to improve the protection efficiency of limited ecological resources. This study is of theoretical significance to the construction of urban green space ecological network in China. It is also of practical significance to verify the feasibility of the method so as to provide a model for other cities to build a reasonable ecological network.
