【摘要】：生态系统服务功能,是从城镇生态资源需求方面评价自然并与自然建立联系的重要指标。在快速城镇化背景下,随着生态环境的恶化,生态系统服务功能逐渐弱化甚至消失。以生态系统服务功能为主线建立生态网络,是提升区域生态系统服务功能、指引城镇合理布局并维持区域可持续发展的重要途径。根据城市发展对生态系统服务功能的需求,初步构建了区域尺度生态系统服务功能指标体系;在GIS技术支持下,采用不可替代性分析方法对生态系统服务功能进行评价,并对其保护与管理进行优先性分析,确定生态核心(eco-cores);根据最小成本路径模型识别连接生态核心的生态廊道(eco-corridors),最终构建基于生态系统服务功能的生态网络,为区域尺度城市生态资源评价、网络优化与可持续发展提供参考。
[Abstract]:Ecosystem service function is an important index to evaluate and establish the relationship between nature and urban ecological resource demand. Under the background of rapid urbanization, with the deterioration of ecological environment, ecosystem service function gradually weakened or even disappeared. Taking ecosystem service function as the main line, establishing ecological network is an important way to promote regional ecosystem service function, to guide the rational distribution of towns and to maintain regional sustainable development. According to the demand of urban development for ecosystem service function, the index system of regional scale ecosystem service function is constructed preliminarily. With the support of GIS technology, the function of ecosystem service is evaluated by the method of irreplaceable analysis. The protection and management are analyzed to determine the eco-coressm, the eco-corridorsof ecological corridor is identified according to the minimum cost path model, and the ecological network based on ecosystem service function is constructed. It provides reference for regional scale urban ecological resources evaluation, network optimization and sustainable development.
