中心城区的生态安全格局构建研究

摘要

本文利用景观生态学的理论,采用最小累计阻力模型,评价深圳市福田区的景观生态安全格局.结果表明,福田区当前存在景观格局破碎、生态安全网络不完善、生态廊道孤立和生态流连接性差等问题.对此,本文提出优化生态节点、生态廊道和生态网络等措施,提出"一心、一轴、一环、三带、六区"的福田区生态安全格局规划,以满足城市发展的需要及保护城市生态系统的生态过程和基本服务功能.%Based on the theory of landscape ecology, this study used the minimum cumulative residence model to evaluate the security pattern of Futian District in Shenzhen city.The results indicated that some problems should be solved urgently in Futian District, including the fragented landscape pattern, unestablished ecological security web, isolated ecological corridors and poor connectivity of ecological flow.To solve the above problems, the optimum measurements were conducted in this paper with con-structing the ecological node and ecological corridor which would build"a core, a ring, three zones and six regions" ecological se-curity pattern of Futian District.The pattern would meet the demands of the city's development, and protect the ecological process and the basic ecosystem services of urban ecosystems.
