摘要
利用GIS建立石匣小流域非点源污染信息的数据库,分别以SCS方程、USLE方程和污染物迁移为核心,初步建立非点源污染负荷模型。模型的界面设计体现了VB面向对象的程序设计,直接在WINDOWS环境下运行。采用实测资料对SCS法进行修正。USLE方程计算,取得较为理想的结果。
Database of non-point source pollution of Shixia Small Watershed is built up by using GIS. At the cores of USLE equation, SCS runoff curve and nutrients transportation, preliminary non-point source pollution model is established. This model can run under Windows environment and has friendly interface. SCS runoff curve method is calibrated by monitoring data whereas USLE equation has good calculated results compared with practical data.
