Study Of Management Models And Policies Of Non-point Pollution Control In A County's Range

As the increasing intensity of the non-point source pollution in Taihu Lake Basin, we investigate the characteristics and difficulties in Tiaoxi river basin, which is a crucial inflow of Taihu Lake, in County Anji according to the classic researches of non-point pollution. We used on-site survey, including field survey, consultation and citizens' environmental awareness survey etc., literature review, experts' advice and mathematical statistics to investigate the related management policies and mechanisms for county-ranged agricultural non-point pollution controlling. This research will advance the management efficiency of county-ranged non-point pollution control.According to the theoretical researches in non-point pollution control and its practice in Anji, the research makes the advance of county non-point source pollution control management model which is led by government and supported by the management of market orientation, public and scientific techniques. In this thesis, I analyzed the merits and applicability of these county non-point source pollution control management models. Optimize the four major categories of the safeguard and management measures. In the management decision-making period, the research improves county non-point source pollution monitoring network, and information disclosure system. In the management implementation, the mechanisms of public participation and diversified investment are created to ensure long-term operation of policy. After the implementation of management policy, the system of monitor and verify is quite necessary.Using the methods of linear regression, AHP and game theory, the research respectively analyzes the effectiveness of the agricultural environmental policy, non-point pollution management models, and safeguard measures in county's range. The result is that the ten environmental policies have the strongest effectiveness. The ten policies are comprehensive agricultural development, township environmental monitoring management station, the river cleaning system, "5211" Talents Scheme, with award generation filling to promote governance, grid management model, agriculture and environmental planning, agriculture and agro-environmental monitoring system, construction of livestock district. Public management model and cooperative management model of non-point source pollution in a county's range has more effectiveness. In the mechanism of policy implementation, it is the main key of policy effective implementation that governmental oversight mechanisms for enterprises of different sizes and financial subsides to the rate of incentives.The research establishes an integrated policy framework of county-ranged management of non-point pollution control, and extracts universal conclusion and recommendation. The integrated policy framework is hold for policy development, including the principles of county non-point pollution control management, the combination of management and policy supporting, policy framework for the management of livestock, rural and agriculture. The integrated policy framework provides a strong support to the county non-point pollution control and management.
