Abstract:Pollution emission coefficient and technical and economic evaluation methods was used, with comprehensive consideration of the environmental benefits and economic gains and the technical and transaction costs of the control of rural non-point source pollution, and an analytical framework and method were developed to analyze the control strategies of regional rural non-point source(NPS) pollution. Results indicated that in Yixing County, total nitrogen and total phosphorus emissions from rural NPS pollution were 2880.94 t and 501.19 t, respectively, causing economic losses of 0.338 billion yuan in 2011. Net present value ratios (NPVR) of four strategies to control various rural NPS pollution, formula fertilization by soil testing, biogas project for large scale livestock and poultry farms, biogas project for scattered livestock and poultry farms and rural sewage treatment project were 55.00, 2.54, 0.52 and -0.15, respectively. Considering technical feasibility, transaction costs and government administrative capacity, the recent priority should be given to the control of pollution from large scale livestock and poultry farms and crop production, while the control of pollution from scattered livestock and poultry farms and rural sewage should be the long-term priorities.
