Status and Prospects of Models for Non-Point Source Pollution

Non-point source pollution has become a severe problem in China and other countries.It is an urgent task to launch research on this problem.It is becoming quite common to develop mathematic models of non-point source pollution for watersheds.Firstly,in the present review paper,the development history of the models in China and other countries is summarized as well as their applications.Secondly,the characteristics,structure and applicable fields of several common used models were analyzed in detail.Finally,prospects and future development of non-point source pollution models were discussed.The paper is expected to provide valuable guidance in non-point source pollution models in China.
