摘要
污染物在径流形成过程中的迁移和转化是很复杂的 ,为了有效地防止和控制降雨径流污染 ,必须对这个复杂过程进行分析、模拟和预测。详细介绍了近年来国外和国内非点源污染模型的研究进展。可以看出 ,GIS与非点源污染模型的结合及在模型中引入模糊理论、不确定性分析、风险管理是今后的发展趋势 ,而我国在非点源污染方面的研究还比较落后 ,有待进一步的发展。
Transfer and transform of pollutants is very complicated In order to prevent and control runoff pollution, the complicated processes need to be analyzed, simulated and predicted The development of recent overseas and inland non point pollution models is introduced in this paper It can be seen that integrating GIS, fuzzy set theory, uncertainty analysis and risk management into non point source pollution model will be future development direction However, it is stil behindhand with this field in China, and remains to be developed
