摘　　要：文章介绍了一种基于数据库支持的非点源污染模型LSPC(Loading Simulation Program in C++),模型思想源于采集数据分析系统(Mining Data Analysis System),其本质是基于C++语言对HSPF(Hydrologic Simulation Program Fortran)模型的二次开发。该模型集合GIS工具、数据管理模块、后续处理模块、水文水质模拟与一体,可以对透水地面、不透水地面、河流和完全混合型湖泊水库三种不同性质的地表水文水质过程进行模拟,模拟的变量包括径流,沉积物,重金属和常规污染物。该模型拥有强大的数据库支持,方便的用户界面以及一些独特的功能等优点。模型不仅能够对水文水质进行模拟,其模拟结果可以用来指导TMDL和BMP的制定与实施,并且方便与其他模型集成,对复杂水环境问题进行管理。文章最后分析了LSPC模型在中国的应用前景。LSPC （Loading Simulation Program in C＋＋）, a non-point source pollution model system based on a databasesupporting architecture was introduced. LSPC which derived from Mining Data Analysis System is a recoded C＋＋ version of selected HSPE （Hydrologic Simulation Program Fortran）. The system integrated GIS tools, data management capabilities, postprocessor and a dynamic watershed model within a common Windows environment is capable of dynamically simulating flow, sediments, metals, temperature, pH as well as other conventional pollutants for pervious and impervious lands and water bodies of varying order. The system with some merits such as database-supporting friendly user interface and special functions has been successfully applied to TMDL （Total Maximum Daily Load） and BMP （Best Management Program） studies and it can be applied in conjunction with a more rigorous hydrodynamic receiving water model to evaluate estuaries and lakes/reservoirs through estimation of appropriate boundary conditions. Application prospects of LSPC in China were described as well.
