| 摘 要： | 农业已被确认为地表和地下水最主要的非点源污染源，而土地利用方式又是影响非点源污染的关键性因素。大规模的土地利用与开发、化肥与农药用量的增加、规模养殖业的发展、生活垃圾的增加等，这些非点污染源严重威胁水体质量，进而影响到人们的生活。为了更好地预测和控制、管理非点源污染，必须研究其负荷定量化问题。本文从以上几方面入手，讨论了非点源污染与农业土地利用方式之间的关系，利用组件GIS技术，以网格为评价单元，实现非点源污染负荷的定量计算及可视化分析。文章最后以上海市松江区作为研究区域，对该区的污染情况进行了分析。

| Abstract: | Agriculture has been considered as the main source of non-point source pollution in the surface and ground water, and the land use styles is the key factor affecting the non-point source pollution. The extensive land utilizes increase, development of the scale feeding, increase of the domestic rubbish with development, chemical fertilizer and agriculture chemical consumption, etc. , these some pollution sources threaten water physique amount seriously, then influence people's life. In order to predict and control, manage some sources to pollute better, we must study its load ration question. This paper proceeds with the above several respects, discusses the relationship of non-point source pollution and the land use styles,and realized the ration and visual analysis of the waste loading using the COM GIS techniques and regarding net as appraise the unit. Finally, Songjiang District of Shanghai is analyzed as an example. |
