摘要
小流域生态系统服务功能分为产品提供功能、调节功能、文化功能和支持系统功能。小流域生态系统的产品提供功能包括提供农业产品(包括种植业产品、牧业产品和渔业产品)、提供原材料和提供淡水资源;小流域生态系统的调节功能包括涵养水源、固定CO2、释放O2、净化环境、净化水源和洪水控制;小流域生态系统文化功能包括旅游价值、文化和科研价值;小流域生态系统的支持功能包括土壤保持、营养物质循环和提供生物环境价值。该文系统阐述上述小流域生态系统各项服务功能与价值的估算方法,对于小流域生态系统服务功能与价值评估具有一定的参考价值。
Ecosystem services value of small watershed include product value, regulating services, cultural services, and supporting services. Product services include agriculture products （food, cotton, livestock, fishery）, raw materials, and fresh water; regulating services include water regulation, CO2 fixation, O2 production, air quality maintenance, water purification, and flood prevention; cultural services include recreation, ecotourism, cultural, and science; supporting services include soil conservation, nutrient cycling, and provisioning of habitat. In this paper, the value assessment methods of all kinds of ecosystem services mentioned above were put forward, which have some significance for the assessment of ecosystem services value of small watershed.
