| 摘 要： | 利用流域地图和地理信息系统(Arcview)软件评估的不同土地利用状况下的基本污染负荷,以太湖流域的子流域——锡山流域为例定量评价了流域的非点源污染. 本文包括根据流域面积和污染物平均浓度模拟流域污染负荷,进而在设施流域最优管理措施的情况下评价非点源污染. 最优管理措施提供最有效的、最实用、最大成本效益的步骤减少流域的非点源污染. 结合流域边界和土地利用资料、营养物的平均浓度、及点源负荷资料,利用WATERSHEDS 3.0 软件的扩展的PLOAD GIS模型评价了非点源污染,并利用表格和图形对模型的模拟结果进行了评估.

| Abstract: | This paper focuses the quantitative evaluation of non point sources of pollution by graphical maps of watershed and estimating area based load of pollutants of various land uses with the use of Arc/View Geographic Information System. The representative study is carried out in the Xinshan sub-watershed of Taihu watershed. It involves the simulation of pollutants load by watershed; watershed area and event mean concentration (EMC) by pollutants. Further the NPSP evaluation is carried out with the provision of Best Management Practice (BMP's) scenario in the watershed. BMP's utilization practice has provided the most efficient, practical and cost effective steps for the reduction of NPSP in the watershed. Using watershed boundary and land use data, nutrient EMC, and point Load, NPSP is evaluated based on PLOAD GIS model extension of Watershed 3.0. Model simulation is evaluated using tabular and graphical analysis. Support for this work is provided in the part by funding from the Natural Science Foundation in China for the project No. 50239030 |
