中小流域综合水质模型系列的建立

ESTABLISHMENT OF THE WATER QUALITY MODEL SERIES FOR SMALL MID SCALE BASIN

根据中小流域的水文特点和实际要求，建立了综合水质模型系列，将河流、水库和非点源污染模型有机结合在一起，并对河流水质模型加以改进，增加了模拟ＣＯＤ和底泥泛起功能，完成了保护水源地的决策性水质模型，模拟和计算了非点源污染随降雨径流进入水体的过程。利用本模型系列可对流域进行优化管理。

Based cn the investigation and hydrological property of a small-mid scale basin, a svnthetical water quality model series were established,which was com-bined with the river water quality model,reseivoir water quality model and nonpoint source pollution model. The river model was modified of COD and seditnent resu-spension,The dicision models of protecting water resources were established.The nonpiont source pollution from agriculture land was simuated and calculated.This model series can be used to optimize management for the river basin.
