基于不同评估方法的养殖池塘富营养化环境成本研究——以上海青浦地区常规鱼类养殖池塘为例
Approaches to Assessment of Environmental Costs of Eutrophication of Aquaculture Ponds-A Case Study of a Conventional Fish Pond in Qingpu Shanghai
摘要
Abstract
Environmental cost of aquaculture in pond was assessed, using the replacement cost method, material balance method, contingent valuation method ( CVM) and COD price method. Results of the assessment show a decreasing order of replacement cost method (4 400 RMB -a-1 ? Hm-2) , COD price method (4 191. 99 RMB ? A-1 ? Hm-2) , material balance method (3 925.76 RMB ? A-1 ? Hm-2) , and contingent valuation method (2 007. 8 RMB ? A-1 ? Hm-2). It is held that the assessment using the COD price method is probably the closest to the true value of the environmental cost on the premises that the costs of time and money are not counted. The environmental costs estimated using the four methods account for about 6% - 14% of the total economic profit of the operation, which indicates that it is necessary to adopt relevant measures to administer aquacultural pollution of the environment.关键词
