摘    要:以干旱区典型沙漠水库——红崖山水库为例,估算干旱区水库生态系统服务的经济价值。结果表明:2007年红崖山水库生态系统服务功能的静态和动态生态价值分别为4.525 2亿元/a和3.529 7亿元/a,其生态系统服务功能的价值主要有:水源涵养1.453 9亿元/a、废物处理1.296 9亿元/a和食物生产1.253 0亿元/a,分别占水库生态系统服务功能静态生态价值的32.13%、28.65%和27.69%,而其他的生态系统服务功能如生物多样性保护、娱乐文化、气候调解等仅占11.53%。

关 键 词:生态系统  价值评估  水库生态系统  红崖山水库  中国干旱区

Abstract:A case study was conducted in the Hongyashan Reservoir, a typical desert reservoir in an arid area of China, to evaluate the economic value of the ecosystem services. The results show that the static value and dynamic value of the ecosystem services of the Hongyashan Reservoir were 452.52 million yuan and 352.97 million yuan, respectively, in 2007. The economic values were derived from water conservation (145.39 million yuan per year), sediment and waste assimilation (129.69 million yuan per year), food production services (125.30 million yuan per year), and other services (including biodiversity conservation, entertainment and culture, and climate regulation), accounting for 32.13%, 28.65%, 27.69%, and 11.53%, respectively, of the static value of the ecosystem services of the reservoir.
Keywords:ecosystem service  value evaluation  reservoir ecosystem  Hongyashan Reservoir  arid area of China
