秋浦河流域生态补偿标准实证研究

流域生态补偿标准是流域生态补偿研究的核心内容,国内外对此观点不一。以秋浦河为例,以2007年为基准,采用国家林业局发布的"森林生态系统服务功能评估规范(LY/T1721-2008)",评估了其上游生态服务价值为5.47亿元。并基于"外部性理论"提出了流域生态补偿标准应本着因地而宜原则,视生态服务的空间差异而定。补偿的上限为外部经济性行为的全部,即生态服务价值的全部5.47亿元,补偿的下限为生态系统服务功能中主导效应因子的价值,即直接使下游受益的水源涵养及土壤保育价值2.16亿元。

Ecological Compensation Standard for Qiupu River Basin

Ecological compensation standard constitutes the core of payment for watershed ecosystem,on which tremendous amount of researches have been done with debating perspectives.Based on the "Assessment Standard for Forest Ecosystem Services(LY/T1721-2008)" published by the Department of Forestry,a case study was conducted on the forest ecosystem of Qiupu River in the base year of 2007.The results show that total value of the forest ecosystem services was about 5.47×108 yuan.Based on the externality principle,ecological compensation standards should be established according to spatial variations of ecosystem services.The upper limit of ecological compensation should not be higher than the total value of forest ecosystem services,while the lower limit should be set as the value of the leading function(e.g,water resources conservation and soil conservation),which was 2.16 ×108 yuan for the study site.
