基于生态绿当量模式的生态资产核算研究——以抚仙湖流域为例

Research on Accounting for Ecological Assets in Fuxian Lake Basin Based on Green Equivalent

生态资产是以货币的形式来度量生态系统为人类社会提供物资和生态服务的价值,核算一个区域的生态资产实际上就是评估一个区域的可持续发展能力。生态绿当量依据"服务功能相当、服务价值相当"的理论,以森林生态系统生态资产为参考标准,能简单、高效、可计量地核算出区域的生态资产价值。通过生态绿当量模式,核算了云南省抚仙湖流域1992—2014年间的生态资产价值。结果表明:1抚仙湖流域1992年、1996年、2001年、2006年、2010年、2014年生态资产价值分别为161.44亿元、162.02亿元、160.56亿元、160.49亿元、160.52亿元、160.45亿元,总体呈逐年下降趋势;2抚仙湖提供的生态价值占总资产价值的90%,湖泊在维持生态稳定方面起着非常重要的作用。

Ecological assets was the amount of money represented ecosystems which provided the material basis and services for human social ac- tivities value, but actually calculating a regional ecological assets was to evaluate supported by the natural environment in the region of the human eco- nomic and social sustainable capacity. Based on the ecological assets of forest ecosystem and the theory of equivalent service value of function, ecologi- cal green equivalent could efficiently calculate the value of region ecological assets. In this paper, based on the ecological green equivalent mode to ac- counte the ecological assets value of Fuxian Lake Basin during the period of 1992 - 2014 year amount. The results showed that： （10 Fuxian Lake Basinin 1992, 1996,2001,2006,2010,2014 year, the total assets respectively were ： 161.44billion yuan, 162.02 billion yuan, 160.56 billion yuan, 160.49 billion yuan, 160.52 billion yuan, 160.45 billion yuan, and the ecological assets value decreased year by year. （2） Fuxian Lake provided ecological val- ue of 90 % in the total assets value, in maintaining environmental stability, the lake played an important role.
