Study on the Control Model of Rural Non-point Source Pollution——Taking Ninghe County in Tianjin as an Example

[Objective] The aim was to study the control model of rural non-point source pollution.[Method] Taking Ninghe County(a typical agricultural county in Tianjin) as an example,the current development of local economy and society and characteristics of rural non-point source pollution were studied firstly,then the control model of rural non-point source pollution suitable for Ninghe County was constructed,and its environmental and economic benefits were analyzed finally.[Result] According to the sources of non-point source pollution,the control model of rural non-point source pollution in Ninghe County was divided into three modules from the aspects of planting industry,livestock raising industry and rural living.The main content of non-point source pollution control module of planting industry was composed of rational utilization of chemicals,water-saving irrigation,diversified utilization of straw etc.Non-point source pollution control module of livestock raising industry focused on the site selection of farm or raising zones,choice of raising mode,comprehensive utilization of livestock waste etc.In the non-point source pollution control module of rural living,villages were divided into two types(small town and ecological village) based on various geographical positions.In a word,these three modules were interrelated and targeted for non-point source pollution control in villages under different development situations.[Conclusion] The study could provide references for the rural non-point source pollution control in Hai River basin and other regions of Northern China.

Construction of the Control Mechanism of Rural Non-point Source Pollution in Nantong City

In view of the problems found in the in-depth interviews of the current situation of rural non-point source pollution control mechanism in Nantong City and their reasons,the following six countermeasures and suggestions are put forward,including giving full play to the role of fighting bastion of the Party branch and building a mechanism for Party building to lead the control of non-point source pollution in rural areas,giving prominence to the dominant role of farmers and establishing farmers’endogenous motivation excitation mechanism for rural non-point source pollution control,improving the interest coordination mechanism among multiple governance subjects and building a modern control system for rural non-point source pollution,combining regulations,administrative,economic,technical and other means of rural non-point source pollution control and strengthening the synergistic integration mechanism of multiple means of control,reconstructing the information disclosure mechanism of rural non-point source pollution control and building a comprehensive trust mechanism of multiple control subjects,and improving the mechanism for coordinating the supply of policy tools and ensure that basic mechanisms play their due role.

Investigation on Farmers'Willingness to Participate in Rural Non-point Source Pollution Control in Nantong and Analysis of Its Influencing Factors

Based on the questionnaire survey of 337 farmers in 8 villages in Rugao City,Jiangsu Province,the gender,age and educational level of the main able-bodied people of farm households,the characteristics of farmers’production and living behaviors,farmers’cognition of rural non-point source pollution,and farmers’willingness to pay for rural non-point source pollution control and its influencing factors were studied.The results show that to protect the rural ecological environment,most farmers are willing to participate in rural non-point source pollution control,but the annual cost of rural non-point source pollution control is low,and the number of volunteer days is small.Rural grass-roots party organizations should stimulate farmers’willingness to participate in rural non-point source pollution control,give full play to the role of the branch as a fighting fortress,and build a mechanism for Party building to lead rural non-point source pollution control.

我国农业面源污染治理模式转型及其法治问题研究——以S县为例

农业面源污染的有效治理具有保护我国生态环境、维护国家粮食安全、促进农业全面绿色转型的重要意义。其治理模式还存在市场、政府单中心治理模式的双重失灵、部门间职权分工不明确、公众参与性偏低等诸多问题。为此,以M省B市S县农村地区为例,采取分析S县农业面源污染治理现状及治理模式存在的问题,架构一种新型的符合S县发展的治理模式,即实现从单一主体治理到政府、市场与农户多元共治治理模式的转型。与此同时,农业面源污染治理体系的高效运转离不开法治的保障,以完善农业面源污染防治的法律体系、建立健全相关配套制度为有效路径,从而改善农业面源污染,实现现代农业绿色发展。
