摘要

SWAT模型是最具有活力的非点源污染模型之一，能够与GIS结合模拟复杂大流域不同土地利用条件下的非点源污染情况。本研究在建立流域非点源污染研究基础数据库的基础上，根据实测资料的完整性，运用GIS与分布式参数机理模型SWAT2000版本的集成，利用1991-1996年的实测水量、泥沙和营养负荷数据进行参数率定，应用1997-1998年的实测数据进行模型验证，从而确定SWAT模型在黑河流域非点源污染模拟中的适用性和可靠性，可为流域非点源污染负荷的估算提供可靠的模型基础。

Abstract

SWA T model is one of the most active non point source pollution models. Combined with GIS，it can simulate non-point source pollution under the different conditions of land use in complex large river basin. This study is based on the basic database of non-point source pollution and the integrity of the measured data and uses the GIS integration with the SWAT 2000 model.Model parameters are estimated using the measured data of water

sediment

and nutrient load from 1991 to 1996 and are verified using measured data from 1997 to 1998.Applicability and reliability of SWAT model in non point source pollution simulation in Heihe River basin are determined，which provides a reliable model foundation for non-point source pollution simulation in Heihe River basin of Shaanxi Province.
