摘　　要：延安生态体系存在生态要素保护压力增大、生态空间利用矛盾突出等问题,该研究以加强区域生态资源管制、引导城市空间有序拓展、为城市可持续发展构建稳定的生态安全格局及创建适宜居住和适宜创业的城市环境为指导思想,遵循生态优先原则、景观连续性原则、多样化原则、格局优化原则及可持续性原则,通过对延安生态资源分布的特征分析,结合延安城市建设空间拓展的规律,构建"环—楔—网"的网络化生态绿地空间模式,旨在构建一个山水资源等生态要素保护全面,生态保育、恢复和建设并举的,空间体系完整、生态分区明确、景观特色显著的生态网络体系。Ecosystem of Yan＇ an City is faced with serious problems such as increasing pressure of protecting ecological elements, and contra- dictions in utilization of ecological spaces. To enhance supervision over regional ecological resources, guide the orderly expansion of urban spaces, construct a stable eco-security pattern for sustainable development of the city, and create an urban environment favorable for living and working, this study follows the principles of “ecology on the priority, landscape continuity, diversity, optimization of layout, and sustainabili- ty”. By analyzing distribution features of ecological resources in Yan＇ an City, considering rules of its urban space expansion, and studying the “ring-wedge-network” spatial pattern of its ecological green spaces, this study is to build an ecological network with complete spatial system, definite ecological zoning and characteristic landscapes in which ecological elements are protected comprehensively, ecological conservation, restoration and construction promoted simultaneously.
