摘要
本文通过对贵州省面源污染的调查与分析,即对降雨径流对城市地表的冲刷所带来的污染物造成的面源污染;化肥、农药不合理使用所导致的农村面源污染;农村生活污水及固体废弃物的乱排乱堆在较大的降雨径流冲刷下的污染;迅速发展起来的集约化养殖场的污染以及水土流失过程中携带大量吸附态污染物的调查与分析,为我省的面污染源治理提供有效的基础依据,为控制和清除水污染、保护水资源提供治理依据.
The investigation and analysis were made for the site pollution source in Guizhou Province. They are divided into the following sectors： pollution caused by pollutants that brought forth by rainfall washing urban surface; pollution eansed by irrational use of fertilizers and agfieuhure chemicals in rural area; pollution caused by rural domestie sewage and randomly piled solid waste that washed by big rainfall runoff; pollution from rapidly developing concentrative euhivation farm; and pollution of mass adsorptives from water loss and soil erosion. It provides the basic foundation for the treatment of the site pollution source in Guizhou Province, for controlling and eliminating water pollution, and for protecting water resources.
