| 摘 要： | 河流生态系统服务功能是指河流生态系统与河流生态过程所形成及所维持的人类赖以生存的自然环境条件与效用,包括河流生态系统产品与河流生态系统服务两个方面。文中分析了河流生态系统的15项服务功能,其中包括供水、水产品生产、内陆航运、水力发电、休闲娱乐和文化美学等6项河流生态系统产品与调蓄洪水、河流输送、蓄积水分、土壤持留、净化环境、固定CO2、养分循环、提供生境和维持生物多样性等9项河流生态系统服务;同时又分析了修建水坝对这此服务功能的影响。研究表明,使河流生态系统服务功能得到正常发挥,是水坝建设决策中应考虑的必要因素。

| Abstract: | River ecosystem service function implies the natural environmental conditions and their effectiveness formed and sustained by the ecological processes of river ecosystem,and includes the two aspects of products and services.In this paper, 15 kinds of river ecosystem service function,including 6 kinds of products(water supply,fish resources,inland navigation,hydro-power,recreation,and culture and aesthetics) and 9 kinds of services(flooding control,soil and sand transporting,water resources storage,soil conservancy,environmental purification,CO_2 fixation,nutrient cycling,wildlife habitat supply,and biodiversity), were introduced,and the effects of dam-construction on them were analyzed.It was suggested that keeping well-balanced river ecosystem service function would be one of the essential factors in dam-construction decision. |
