水生态系统服务功能价值评价——以常熟市陶荡面为例

Value Evaluation of Water Ecosystem Services

[目的]定量评价水生态系统的服务功能价值。[方法]以常熟市陶荡面湖泊为例,建立了由淡水供应、休闲娱乐、水质净化、维持生物多样性4项功能构成的水生态系统评价体系,采用市场价值法、旅游费用法和恢复费用法对陶荡面的生态服务功能进行了评价与估算。[结果]陶荡面淡水供应价值和休闲娱乐价值占优,二者产生正效益,而水质净化和维持生物多样性功能产生负效应,表明陶荡面生态环境呈恶化趋势,亟需通过污染控制与生态修复等技术进行治理与保护。[结论]该研究为水资源的开发利用与保护提供了科学依据。

[Objective] The study aimed at quantitatively assess the values of water ecosystem services.[Method] Combining the market value,travel cost and restoration cost method,the ecological services and their economic values of Taodangmian Lake were assessed from aspects of water supply,recreation and tourism,water purification and biodiversity maintenance.[Result] For the lake Taodangmian,its freshwater supply and tourism played more positive roles in the society than the others,while the functions of water purification and biodiversity maintenance brought negative effects,which shows that the ecological environment of Taodangmian has become increasingly worse and needs to be controlled and protected further.[Conclusion] The research could provide scientific references for the reasonable exploitation and utilization of water resources.
