Pond aquaculture has existed in China for thousands of years, which has not only contributed great economic value, but also presented cultural value for human beings. With the development and upgrading of Chinese economy and culture, these values will be highlighted further. To evaluate the cultural service value of pond aquaculture ecosystem would provide a scientific base to the policy-making to avoid or reduce the wrong design-making or avoid the policy-malfunction, and also, to promote the development of aquaculture and related recreational fishing industry, increase the added value of aquaculture and the income of fish-farmers, and promote the economic development of rural area. Based on the survey data from the aquaculture ponds in the water conservation area of Dianshan Lake in Qingpu District of Shanghai and the related statistical data, the cultural service value including recreational value and existence value of the aquaculture pond ecosystem in the area was estimated by means of travel cost method (TCM) and contingent valuation method (CVM). The total cultural service value of this ecosystem was about 213 million Yuan x a(-1) or 231296. 69 Yuan x hm(-2) x a(-1), being 5. 25 times of the market value of aquaculture products, among which, recreational value was about 189 million Yuan x a(-1), and existence value was about 24 million Yuan x a(-1). It was suggested that in the construction of new rural areas of Shanghai, sufficient attention should be paid on the full play of the cultural service value of aquaculture pond ecosystem.
池塘养殖在中国已有数千年历史，它不仅创造了巨大的经济价值，还为人类展现了文化价值。随着中国经济和文化的发展与升级，这些价值将得到进一步凸显。评估池塘养殖生态系统的文化服务价值，可为政策制定提供科学依据，避免或减少错误设计或政策失灵，同时促进水产养殖及相关休闲渔业的发展，增加水产养殖附加值和渔民收入，推动农村地区经济发展。基于对上海青浦区淀山湖水源保护区内养殖池塘的调查数据及相关统计数据，采用旅行成本法（TCM）和条件价值评估法（CVM）对该地区养殖池塘生态系统的文化服务价值（包括休闲价值和存在价值）进行了估算。该生态系统的文化服务总价值约为2.13亿元/a或231296.69元/hm²·a，是水产养殖产品市场价值的5.25倍，其中休闲价值约为1.89亿元/a，存在价值约为2400万元/a。建议在上海新农村建设中，应充分重视发挥池塘养殖生态系统的文化服务价值。
