摘要
绿色基础设施(Green Infrastructure,GI)具有重要的生态服务功能和人文服务功能,但实践应用中存在着对特定绿色基础设施的级别、特征、结构和空间范围认识不清等诸多问题,因此需要对其进行识别。生态旅游的发展在一定程度上激化了绿色基础设施内部生态与游憩活动之间的矛盾,而结合两大服务功能对其进行优化是解决问题的途径。文章结合安徽宣城南溪湿地生态旅游区实例,运用GIS分析法,提出了中小尺度绿色基础设施识别与优化方法,旨在为绿色基础设施的实践应用提供可操作的手段。
Green infrastructure（GI） has important functions of ecosystem service and humanistic serw ice. But there are still many difficulties in practical application, such as the ignorance of specific green infrastructure level, characteristics, structure and spatial range. Therefore, it is necessary to identify green infrastructure before construction. At the same time, the development of ecological tourism has intensified the contradiction between the ecology and recreation within the green infrastructure to some extent. The integration of the two service functions to optimize it is the way to solve the problem. Taking Nanxi Wetland Ecological Tourist Area in Xuancheng, Anhui Province as an example, this paper puts forward the method to identify and optimize the small and medium-sized green infra- structure by using geographic information system（GIS） analysis. This method is valuable for provi- ding operational means for the application of green infrastructure.
