摘要: 生态系统服务功能动态区划系统(SIZES)是自动实现区域生态系统服务功能动态区划边界识别的软件工具,能够辨识区域生态系统服务功能空间分异特征,指导区域生态系统服务功能分区管理。SIZES采用多源数据融合技术,通过分层输入区域生态系统服务功能的表征指标,利用因子分析法与空间模糊聚类分析法实现区域生态系统服务功能动态区划边界的辨识。在案例区鄱阳湖湖区的应用表明,利用SIZES划定的10个生态系统服务功能分区科学、合理地解释了该区生态系统服务功能的空间分异特征,为当地生态系统服务功能分区管理提供了参考信息。

Abstract: System  for identifying and zoning ecosystem services (SIZES) a software tool for automatically identifying and delimitating the zoning boundaries of ecosystem services divisions, which can identify the spatial heterogeneity of ecosystem services and give guidance to the regional ecosystem management. SIZES integrates multi-source data, and then, identifies the kernel ecosystem services and delimitates the boundaries of ecosystem services by factor analysis and spatial fuzzy clustering analysis after hierarchically inputting relevant indicators. A case study on the application of SIZES in Poyang Lake area showed that the ten ecological zones delimitated by the system explained the spatial heterogeneity of ecosystem services of the study area, being helpful to provide valuable spatial and temporal decisionmaking information for the local ecosystem services management.
