池塘养殖在我国已经有几千年的历史.这种生产模式不仅具有经济功能,还具有文化价值.随着我国经济与文化水平的提高,这种价值将会进一步凸显.对其生态服务价值的评估,可为渔业经济政策的制订提供科学支撑,避免政策扭曲及其所产生的政策失灵,科学地发展水产养殖业及相关休闲服务业,增加养殖经济的附加值,进而提高渔民收入,促进农村经济发展.本文以上海市青浦区淀山湖水源保护区养殖池塘作为研究对象,以实证调查数据为基础,结合该区的相关统计数据,将养殖池塘的文化价值分为游憩价值和存在价值,并在此基础上,以旅游成本法(TCM)和条件价值评估法(CVM)分别对这两种价值进行了估算,测算了总的文化服务价值.结果表明:该区养殖池塘文化服务总价值约为每年2.13亿元,约合231296.69元.hm-2,是该池塘养殖水产品产量市场价值的5.25倍.其中游憩价值约为1.89亿元,存在价值0.24亿元.在推动上海新农村建设的过程中,职能部门需重新认识此类系统的价值.
Pond culture has been in our country for thousands of years, and this mode of production not only has economic functions but also has cultural value, which will be further highlighted with the improvement of our economy and culture level. Assessment can provide scientific support for the formulation of fishery economic policies, avoid policy distortions and the resulting policy failures, scientifically develop aquaculture and related leisure services, increase the added value of the breeding economy, and thus increase fishermen’s incomes and rural areas Economic development.In this paper, the aquaculture ponds in Dianshan Lake Water Source Protection Area in Qingpu District of Shanghai as the research object, based on the empirical investigation data and the related statistical data of the area, the culture value of the aquaculture ponds is divided into the recreational value and the existent value Based on this, we estimate the value of these two kinds of values by using the methods of TCM and CVM, respectively, and estimate the total value of cultural services.The results show that the total value of cultural services in aquaculture ponds in this area is about For each year 2.13 billion yuan, about 231296.69 yuan.hm-2, is 5.25 times the market value of the aquaculture production of aquaculture ponds, of which the recreational value of about 1.8 900 million yuan, with a value of 24 million yuan .In promoting the new rural construction in Shanghai, the functional departments need to re-understand the value of such systems.
