【摘要】 本研究以太湖为研究对象,基于2007年完成的太湖湖泊生态系统的科学调查数据,综合运用生态学及经济学方法,对太湖生态系统的四大类功能(供给功能、调节功能、支持功能和文化功能)和十一个亚类的服务价值(供水功能,提供水产品,航运功能,水力发电,大气调节,输沙功能,水质调节,调蓄洪水,蓄水功能,土壤保持,旅游功能)进行综合评估。结果表明,2007年太湖湖泊生态系统服务功能总价值为1 500.372 3亿元,其中:供给功能价值973.719 3亿元,调节功能价值140.861 4亿元,支持功能价值30.761 6亿元,文化功能价值363.03亿元。在具体服务子功能类型分类中,比例明显大于其他类型的依次是航运(35.89%)、供水(27.71%)以及旅游(24.07%)。由此表明,太湖湖泊生态系统在航运功能、供水功能及旅游功能等方面发挥着重要作用,它们是太湖的核心服务功能。本研究可为太湖水污染事件的经济损失评估、生态恢复、水资源保护与管理提供数据基础。更多还原

【Abstract】 Taihu Lake was targeted as a case study and data of ecosystems of Taihu Lake in 2007 was collected.An integrated method of economy and ecology was applied to estimate the value of lake-ecosystem service functions.In this study,the ecosystem service functions of Taihu Lake were divided into four main categories(provision,regulation,culture and support) and eleven subcategories(water supply,aquatic products,shipping,hydro-power,climate regulation,soil and sand transportation,water purification,flood control,water resource storage,soil conservancy,and tourism).The results indicated that total value of ecosystem services of Taihu Lake in 2007 was RMB150.04 billion.In all of 11 subcategories,the values of shipping,water supply and tourism were made up of 35.89%,27.71% and 24.07% of the total value,respectively.Therefore,it was obvious that Taihu Lake watershed played a vital role in shipping,water supply and tourism,which were the key ecosystem service functions.This study can provide the basic data for estimation of economic loss caused by the water pollution of Taihu Lake,its ecological restoration,water conservation and management.更多还原
