| 摘 要： | 以全国水资源综合规划为契机,对长湖流域非点源污染展开研究.利用GIS技术,对长湖流域非点源污染负荷进行估算与分析.计算结果表明： （1）水田是长湖流域重要的化学需氧量（COD）、总氮（TN）和总磷（TP）非点源污染来源,分别占88.6%、94.6%和82.5%; （2）长湖流域COD、TN、TP的非点源污染负荷均已超过点源污染负荷;（3）长湖流域非点源污染的形成因素包括人口因素、农事活动、畜禽养殖、水产养殖等诸多因素,但农业生产活动是最主要的因素.

| Abstract: | Study of Non-point Pollution has been carried out to analyze and assess the pollution loads of Changhu Drainage-area using Geographic Information System techniques during the national water resource synthesis plan. The study results shows： （1） Paddy field is the key source of COD. TN and TP pollution in ChangHu Drainage- area, there proportion are 88.6%, 94.6% and 82.5% accordingly. （2） Non-point pollution loads of COD. TN and TP of Changhu Drainage-area had exceeded point pollution loads. （3） The causes of in the form of non-point pollution of ChangHu are population, agriculture action, stockbreeding, aquicuhure and etc.., but the farming is the primary factor. |
