基于能值理论的环洞庭湖区农业生态系统绿色GDP核算研究

运用能值理论通过对湖南环洞庭湖区2009年农业生态系统投入、产出的定量分析,计算了该区域农业生态系统所消耗的不可更新环境资源、不可更新工业辅助能的能值-货币价值,进而核算了该区域农业生态系统的绿色GDP。结果表明:经过调整后2009年该区域农业生态系统的绿色GDP应为177.61亿元(传统GDP为491.60亿元),绿色GDP占传统GDP的比重仅为36.13%,说明该生态系统的经济增长模式仍是一个建立在资源消耗和环境污染基础上的粗放型经济增长模式,"两型"建设任重而道远。

The Green GDP Accounting of Hunan Dongting Lake Area: Based on the Emergy Theory

After quantitative analysis of agroecosystem''s inputs and outputs of 2009 Hunan Dongting Lakearea by using the emergy theory, the emergy-monetary value of non-renewable environmental resources and non-renewable industrial supplementary energy have been calculated. The result shows that the emergy green GDP of the system in 2009 is RMB 177.61 billion yuan which is only 36.13 percent of the traditional GDP(491.60 billion Yuan). This indicates that the economic growth mode of the area is still a kind of extensive economic growth mode which comes from the expansion of ordinary inputs of labor, reproducible capita and natural resources, and the environment-friendly society has a long way to go.
