摘要
利用GIS和非点源污染模型SWAT分析出深圳市的主要水源地水库的汇水区域,根据收集的专题数据,在GIS软件的支持下,从土壤侵蚀敏感性和"源""汇"景观空间分布状况2个方面对水源汇水区的非点源污染现状进行了评价,得出了深圳市6个主要水库水源地的非点源污染的关键因子,并提出了一些汇水区内生态环境的保护措施。
Catchments in main water source reservoir in Shenzhen City were analyzed based on GIS and non-point source pollution SWAT.According to the gathered special data,under the support of GIS software,the actuality of the non-point source pollution in water catchment was evaluated from the soil erosion sensitivity and spatial distribution status of "source" and "sink" landscape.Key factors of non-point source pollution in water sources of six main reservoir in Shenzhen City were obtained.And the protection measures of ecological environment in water catchment were put forward.
