利用WASP模型和GIS可视化集成的水质监测与模拟——以渭河为例

近年来,随着经济发展大量工业和生活污水的大量排放,严重的影响了河流水质状况,作为黄河主要支流的渭河流域更是如此.根据渭河下游水环境特性,选取化学需氧量(COD)作为水质模拟因子,采用WASP水质模型对渭河下游水质进行监测和模拟,将GIS集成到WASP水质模拟中同时利用外联式集成利用GIS对渭河下游水质的时空变化特征进行...

The Water Quality Monitoring and Simulation Based on WASP Methed and GIS Visualization in the Lower Reaches of Weihe River

In recent years,along with the economic development of industry and sewage of emissions,which seriously effect the condition of water quality of the river.As the Yellow River main tributaries,especially Weihe river basin.According to the water environment characteristics in the lower reaches of WeiHe River,the paper selects COD as a factor and chooses the WASP method to do the simulation and evaluation,applies the GIS technology in WASP water simulation,and uses GIS to analyze the water quality Temporal and spatial variation.It uses the outreach integrated method to research of Wei River main pollutant concentration,the space-time distribution of COD and water quality changing trend,then according to the results,it analyzes the causes of the pollution in lower reaches of Wei River Simply,and also explores the targeted control suggestions.
