| 摘 要： | 采用分布式水文模型(GBHM2),基于GIS/RS平台,按照渭河流域现状地理、地貌、土地利用类型、植被覆盖条件和2004年社会经济情况,构建了模型需要的空间数据库与属性数据库,模拟了研究区域渭河流域现状条件下,9个子流域日径流量的变化,取得了满意的成果。在此基础上,借助GIS技术,分析了流域工业与生活污染源CODCr在各模拟子流域中的分布情况,结合流域丰、枯水期CODCr这一特征指标的变化,同时考虑了流域点源与面源有机污染负荷的影响,确定了各模拟子流域年CODCr污染负荷消减系数,实现流域水环境功能目标,流域模拟年CODCr污染负荷削减总量为15.7万t。

| Abstract: | According to the need of GBHM2 model,with the assistance of GIS and some other statistical literatures,two categories of database including the spatial and attributive information of the Weihe River basin were obtained. This model was applied to simulate the total water quantity of the Weihe River in different inputs and the spatial and temporal distribution characteristics of the current runoff and precipitation of each sub - water- shed. The study results were sound. Finally,based on the pollution load an... |
