摘要: 草地生态系统为人类提供了畜产品和生命支持两个方面的多种服务功能,但人们常关注产品提供功能而忽视生命支持功能。研究采用联合国千年生态系统评估框架,构建了海河流域草地生态系统服务功能的评估指标体系,并以2005年为基准年,运用市场价值法、影子价格法等多种方法对海河流域草地生态系统进行经济价值评估。结果表明,海河流域草地面积为6.67×1010 m2,提供产品、固碳、保持土壤、净化环境等8项服务功能的总价值为2 216.28×108元,单位面积价值为3.32元/(m2·a)。其中,提供产品的价值量最大,占总价值的31.3%,其次是固碳和营养物质保持功能的价值,分别占总价值的26.8%、22.2%。海河流域草地生态系统除了具有重要的产品提供功能外,固碳、营养物质保持等生命支持功能的巨大经济价值也不容忽视,平衡兼顾草地生态系统的产品提供功能和生命支持功能有助于促进海河流域经济社会发展与生态保护的协调。

Abstract: Grassland ecosystems not only provide productions such as livestock products and plant resources, but also support people’s lives. People always focus on the production function, while neglecting the life-supporting function. In this research, we use the classification method of Millennium Ecosystem Assessment, that is to divide the ecosystem services into four groups of provisioning, regulating, cultural, and supporting services, and take 2005 as the base year for all types of assessment. Based on the analyses of the grassland ecosystem services of the Haihe River Basin, this study establishes the assessment indexes system and develops economic value assessment using different methods, such as market valuation method, shadow engineering and so on. The result shows that the total economic values of 8 services of grassland ecosystem is 221.628 billion yuan. Among them, provisioning service has the largest value, followed by carbon fixation and nutrients conservation, accounting for 31.3%,26.8% and 22.2% of the total value respectively. This evaluation is conducive to the development, utilization and protection of the grassland resources and can play a guidance role in the management of the grassland ecosystem in the study area. It points out that carbon fixation and oxygen release, nutrients conservation and other life-supporting functions should not be neglected while protecting the local provisioning service to support the economic development, so as to achieve the coordination between the socio-economic development and ecological protection in the Haihe River Basin.

Key words: grassland ecosystems, ecosystem services, economic value, Haihe River Basin
