But in China, nonpoint source pollution control is still at its early stage, many related programs and policies are absent, researches and practices of controlling NPS pollution are scarce. Projects based on BMPs, which were proved successful in controlling nonpoint source pollution in developed countries, are also increasingly utilized in China＇s nonpoint source pollution control. Designing a successful project includes 9 items such as identifying the water quality problems, stating the water quality problems, defining objectives and goals, obtaining funds, involving the community, cooperating and coordinating among agencies, outlining the critical and sensitive areas and so on.展开更多
