The Economic Benefits Of Agricultural Non-P Oint Source Pollution Prevention And Contr Ol Bengbu City

How to control agricultural non-point source pollution effectively, is an important problem in the process of urgent rapid economic development of modem China society.Agricultural non-point source pollution prevention and control measures in our country farmland is divided into non-point source pollution prevention and control measures, the rural sewage non-point source pollution prevention and control measures, livestock breeding non-point source pollution prevention and control measures, and four kinds of comprehensive agricultural non-point source pollution prevention and control measures. Bengbu city as the main measures to prevent and control agricultural non-point source pollution has taken, formula fertilization by soil, large-scale livestock breeding biog as pool project, rural residential sewage treatment engineering, livestock farmers biog as pool engineering and ecological ditch measuring farmland (canal, Tang) and riparian buffer zone construction etc.. The cost of these measures, by the construction cost and operation and maintenance cost is composed of two parts; these measures of income, consists of two parts: direct benefits of agricultural non-point source pollution prevention and control and indirect benefits. Agricultural non-point source pollution prevention and control of indirect benefits, is actually the loss of agricultural non-point source pollution, including the direct economic loss caused by agricultural non-point source pollution and agricultural non-point source pollution to the environment pollution and health damage and disasters caused by indirect losses. Agricultural non-point source pollution caused by the direct economic loss, first of all, including farmland non-point source pollution loss, refers to the unreasonable use of chemical fertilizers, causes loss of chemical fertilizer and agricultural production; Secondly including livestock breeding non-point source pollution loss, that is, not for effective utilization of wastes arising from the livestock farming. Agricultural non-point source pollution prevention and control measures of income minus the cost, is the economic benefit of various kinds of agricultural non-point source pollution prevention and control measures. By comparing the prevention and control measures of high and low economic efficiency, to judge the feasibility and superiority of the prevention and control measures, for the government in the prevention and control of agricultural non-point source pollution and money reasonable dual goal constraints, choose the best and reasonable prevention and control measures to provide the reference and policy Suggestions. By analyzing and comparing all kinds of agricultural non-point source pollution prevention and control measures taken by the Bengbu economic benefits, the author of the following specific conclusions:(1) under the existing technical level, the farmland non-point source pollution prevention and control measures the soil testing and fertilizer technology both ability to cut pollution and the economic benefits of the prevention and control measures, are higher than other control measures, the effective prevention and control measures is fully staffed.(2) biog as engineering not only can prevent and control agricultural non-point source pollution, can also solve the problem of peasant household energy use, help to promote arts and urbanization and new rural construction.(3) the use of selective ecological ditch,(drainage, pond) and the shore buffer prevention and control measures, whether short-term or long-term, can achieve the goal of prevention and control of agricultural non-point source pollution.
