小流域农业面源污染及综合治理进展

Progress of Agricultural Non-point Source Pollution and Comprehensive Control in Small Watershed

江河水体污染在社会发展进程中愈演愈烈,对经济和区域内的生态环境造成了严重的影响,因而受到国家的重点关注。要防治江河水体污染需要明确诱导因素,其中小流域面源污染则为关键来源之一。要对此进行综合治理,要明确小流域农业面源污染的特征,并相应在管控、政策以及工程技术方面着手,同时也要加强后期维护。

The pollution of rivers and waters is intensifying in the course of social development,which has a serious impact on the economy and the ecological benefits of the region,so it has been the focus of national attention.The prevention and control of pollution of rivers and rivers requires clear inducing factors,and non-point source pollution in small watersheds is one of the key sources.To comprehensively manage this,it is necessary to clarify the characteristics of agricultural non-point source pollution in small watersheds,and to proceed accordingly in terms of management and control,policies,and engineering technology,as well as to strengthen post-maintenance.
