养殖池塘小气候调节生态服务价值的实证研究

养殖池塘在为人类提供水产品的同时通过水面水汽蒸发及周围植被的蒸腾作用发挥增湿调温小气候调节功能。对其生态服务价值做出准确的评估，可为利益相关者正确衡量水产养殖业对社会发展的贡献、继而制定正确决策提供科学依据，并为该领域的研究提供讨论的基础。为此，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，以该区常规鱼类养殖池塘的跟踪观测数据为基础，结合相关统计数据和估计模型，定量分析了该区域池塘养殖的小气候调节生态服务价值。研究表明该区养殖池塘小气候调节生态服务价值约为1.794亿元/a（183 437.67元/(hm²·a）)。池塘养殖的小气候调节生态服务价值季节性变动明显.

STUDY ON THE ECOSYSTEM SERVICE VALUE OF MICRO CLIMATE REGULATION SERVICE OF POND AQUACULTURE SYSTEM

Aquaculture ponds produce aquatic products for human being，and can regulate the micro climates through evaporation of the ponds and transpiration of the surrounding vegetation.Accurate assessments on the ecosystem services value can help stockholders correctly measure the contribution of the industry to the society，provide a scientific basis for proper decision and further study in the field of evaluation of pond aquaculture ecosystem.Taking Dianshan Lake in Qingpu District，one of the water conservation areas in Shanghai，as the study area，based on the observed data and the relevant statistical data，this paper quantitatively analyzed the ecosystem service value of the micro climate regulation.The result showed that this ecosystem service value in the water conservation area was approximately 179.4 million yuan/a (18343767 yuan/(hm2a)).This value varied significantly with the change of the seasons.
