摘要
以南京市溧水区方便水库为研究对象,运用Arc GIS对其汇水区域进行子流域划分,同时结合遥感技术对各子流域污染源强度和空间分布进行模拟,确定方便水库各入库河流主要污染源及汇水区域内污染源强度分布情况,然后利用实际监测值对Arc GIS模拟值进行验证。结果表明:Arc GIS技术可直观反映各入库河流汇水面积大小及各污染源强度的空间分布情况;Arc GIS估算值与实测值计算的污染物入库量的误差范围在10%以内。
The Fangbian Reservoir in the Lishui district of Nanjing City was selected as the study object.The ArcGIS technology was used in the watershed subdivision of catchment area in Fangbian Reservoir,and then combined with the remote sensing technology,this study simulated the pollution intensity and spatial distribution to determine the main pollution source of inflow stream and the intensity distribution of pollution source.After that,the simulating results of ArcGIS has been validated by the actually monitored water quality.The results showed that the catchment area of inflow stream and spatial distribution of pollution source intensity can be directly reflected by the ArcGIS technology.Besides,the difference of pollution emission amount calculated between the ArcGIS simulation and the surveyed data was less than 10%.
