基于GIS的水源涵养功能评价研究——以福建省为例

Study on Evaluating the Water Resource Conservation Function Based on GIS Technique

水源涵养是生态系统的重要服务功能之一。根据国内外对水源涵养功能重要性评价的研究成果以及福建省的自然环境特征,确定主要影响因子的评价指标和重要性等级。在ArcGIS9.0软件的支持下,完成了评价指标数据提取和集成,并按照重要性等级标准进行水源涵养功能重要性评价。

Water conservation is one of the important function of ecosystem serves.With reference to domestic and international work on the function of water conservation and the natural environment characteristics of Fujian Province,the primary influences and important grades of water conservation were determined.ArcGIS9.0 software was utilized to index resulting data and to extrapolate the function of water conservation.
