HSPF模型及其在非点源污染研究中的应用

HSPF（Hydrological SimulationProgram-Fortran）模型是将数学方法应用于水文计算和预报形成的流域水文模型，可对陆地表面、亚表面和地下水的水文路线以及污染物的输移进行模拟，广泛应用于不同尺度流域的非点源污染模拟研究，为流域管理措施的制定和实施提供有力的依据．本文总结了HSPF模型的发展过程、模型的结构特点，分析了该模型在国内外应用实例中的可靠性以及存在的问题．最后根据该模型的限制因素，指出了应用中的改进方向．

HSPF Model and the Application in the Study of Non-Point Source Pollution

HSPF（Hydrological Simulation Program--FORTRAN） model is a hydrological model that applies the mathematical methods to the hydrologic calculation and forecasting, it can simulates the hydrologic route and pollutants transportation of land surface, sub- surface and groundwater it was widely used in different scales basin non-point source pollution simulation studies, provided strong basis for establishing and implementing watershed management measures. The paper summarized the development and the structure features of the HSPF model, analyzed the reliability of applying the model in the specific examples. Finally base on the constraints of the model, pointed out the improvement direction in the application.
