【摘要】：选择浙江省南部山区泰顺县作为研究区域,对全县各类生态系统服务价值进行了定量评估,并在此基础上进行了生态系统服务重要性及其区域分异规律的综合评价。结果表明:2012年全县生态系统服务总价值为334.1×108元,是当年该县GDP的6.40倍,其中以水源涵养、气候调节、土壤保持服务价值为主,三者分别占总价值的62.35%、21.8%、7.16%,生态系统有着巨大的间接服务价值。生态系统服务重要性分析结果显示,极重要、很重要、重要区、一般重要区域分别占全县总面积的31.43%、34.57%、20.35%、13.64%,评估结果可为生态系统的科学管理、生态保护关键区的确定以及生态保护和建设政策的制订提供理论依据。
[Abstract]:This paper selected Taishun County in the southern mountainous area of Zhejiang Province as the research area and evaluated the service value of all kinds of ecosystem in the whole county quantitatively. On the basis of this, the importance of ecosystem service and the rule of regional differentiation were comprehensively evaluated. The results showed that the total value of ecosystem services in 2012 was 334.1 脳 10 ~ 8 yuan, which was 6.40 times of that county's GDP in that year, in which water conservation, climate regulation and soil conservation were the main services. The three accounted for 62.35 and 21.87.16 of the total value, respectively. The ecosystem has great indirect service value. The results of the analysis of the importance of ecosystem services show that the most important, important areas and general important areas account for 31.4334.57 and 20.3513.64aspects of the total area of the county, respectively. The results of the assessment can be used as scientific management of the ecosystem. The determination of the key areas of ecological protection and the formulation of ecological protection and construction policies provide theoretical basis.
