| 摘 要： | 采用以新安江蓄满产流理论为核心的太湖流域产流模型计算张家港西南片地区4种土地利用类型的产流量,与美国EPA开发、基于GIS的非点源模型PLOAD结合,探讨PLOAD模型在江苏南部平原地区非点源计算中的应用,重点讨论各种土地利用径流系数和PLOAD模型输入参数的选取。计算了1998～2002年该地区的非点源产污负荷,并分析产污规律和不同土地利用下非点源污染的空间分布规律。结果表明,非点源产污与降雨年际变化趋势基本一致,与降雨量和降雨强度有关;各种非点源产污量大小排序为:COD>总氮>氨氮>总磷;工矿用地和城镇等不透水区域非点源产污量最大,水旱轮作农田次之。

| Abstract: | Taihu watershed runoff model used to calculate runoff of Xinanjiang in Southwestern Zhangjiagang, Jiangsu Province was combined with PLOAD model based on GIS to calculate non-point source load in the area, with emphasis on the application of PLOAD model in plain area and selection of input parameter. Annual loads of non -point source from 1998 to 2002 were calculated, the spatial distribution rules of COD, total N and total P in different land use as well as the inter-annual variable rule were analyzed. Results indicated that non-point source pollution was identical with precipitation and closely related with precipitation and intensity. |
