摘　　要：生态廊道是指连接斑块的带状空间,能确保生态过程的连续性,有利于维持和恢复自然生态系统功能,减少经济社会发展对生态系统功能和服务的不利影响,可兼顾环生态、景观和人文等层面,极大增强新城的吸引力。本文以南京仙林新城为研究对象,首先调查分析仙林新城绿色基础设施状况,总结仙林绿地发展现状与问题,基于GIS平台,采用最小路径(LCP)方法,确定潜在生态廊道;并通过重力模型的计算,提取重要生态廊道,构建新城的生态廊道网络,并对廊道网络指标进行分析和评价;再结合各片区的具体绿地规划的要求与特点,构建新城绿地多层级、多元功能要求的综合绿地生态网络;最终总结并提出新城绿地生态网络的优化策略。Eco-corridor refers to the zonal space that connects patches.It can ensure the continuity of ecological processes,help to maintain and restore the functions of natural ecosystems,reduce the adverse effects of economic and social development on ecosystem functions and services,and take into account the levels of ecology,landscape and humanities,so as to greatly increased the attraction of new towns.This paper takes Xianlin New Town in Nanjing as the research object.Firstly,it investigates and analyses the status of green infrastructure in Xianlin New Town and summarizes the development status and problems of Xianlin green space.Based on the GIS,the potential ecological corridor is determined by the LCP (least cost path).Through the calculation of gravity model,the important ecological corridors are extracted.Then the ecological corridor network of the new town is constructed,and the corridor network indicators are analyzed and evaluated.Combined with the specific green space planning requirements and characteristics of each area,the comprehensive green space ecological network with multi-level and multi-functional requirements of the green space of the new town is constructed.Finally the paper summarizes and puts forward the new town green space ecological network optimization strategy.
