【摘要】：池塘养殖具有食品供给、空气质量调节、文化服务等多重功能,但在其生产过程中也会产生环境成本。正确认识池塘养殖的正、负生态服务价值,对于避免养殖生产过程中存在的盲目和短视、保持水产养殖业本身的可持续发展、促进水产养殖经济与环境的和谐发展具有重要的现实意义。依据双边界二分式CVM法,通过随机抽样调查法获得当地居民对于环境污染时的受偿意愿(WTA)水平,利用STATA10.0软件定量核算了2010年上海环淀山湖地区的池塘养殖环境成本为1982.26万元/a,约合5105元.a-.1hm-2)。研究表明,居民家庭收入、受教育程度、年龄等社会经济因素对居民的环境污染受偿意愿具有显著性的影响,但其具体的影响力大小和方向还有待进一步的探讨。研究同时表明,双边界二分式CVM法具有较强的稳定性,政府应综合考虑各种因素,制定并执行针对性、公平性的生态补偿政策。
[Abstract]:Pond culture has many functions, such as food supply, air quality regulation, cultural service and so on. It is of great practical significance to avoid blindness and shortsightedness in the process of aquaculture production, to maintain the sustainable development of aquaculture itself and to promote the harmonious development of aquaculture economy and environment. According to the dual-boundary dichotomy CVM method, it is of great practical significance to avoid blindness and shortsightedness in the process of aquaculture production. The level of local residents' willingness to be compensated for environmental pollution was obtained by random sampling survey. In 2010, the environmental cost of pond culture in the area around Dianshan Lake in Shanghai was calculated quantitatively by using STATA10.0 software. The cost of pond culture was nineteen million eight hundred and twenty-two thousand and six hundred yuan / a, about 5105 yuan. A. Social and economic factors such as household income, education level, age and so on have significant influence on residents' willingness to compensate for environmental pollution, but their specific influence and direction need to be further discussed. The dual-boundary dichotomy CVM method has strong stability. The government should consider all kinds of factors and formulate and implement the ecological compensation policy of pertinence and fairness.
