Progress in the Research of Water Environmental Nonpoint Source Pollution Models

Water environmental nonpoint source pollution has caused serious eco-environment problems,and the quantitative identification of nonpoint source pollution is an international research focus,of which the most direct and effective means is mathematical simulation,and the establishment of a practically-aimed non-point source pollution mechanism model has become an effective means for nonpoint source pollution management and control.The development,functions and current problems of domestic and international nonpoint source pollution models,along with the construction approaches of nonpoint source pollution mechanism model,are briefly described,and the future studies are prospected in this paper.
