摘要: 能值分析法用于衡量人和环境对经济发展的贡献,是一种衡量区域可持续发展的重要指标。本文运用能值分析这种定量化分析技术,对吉林省延边朝鲜族自治州的生态经济系统中主要资源的能值指标进行了系统分析,并将之与其他国家或地区进行比较。结果表明,延边地区的电力利用占总能值使用量的78.47%,分别为美国和日本的39%和33.19%;能值可持续发展指数为19.45,表明该地区处于不发达状态。与此同时延边自治州的环境负荷率仅为0.627,丰富的资源与较小的环境压力有利于发展当地经济。在此分析基础之上,对延边的可持续发展提出了有效的政策建议。

Abstract: Emergy evaluation measures the human and environment's contribution to a region's economy.It is an important index of sustainable development.As a technology of quantitative analysis,the energy analysis of Yanbian's main resourses in Jilin Province was performed and compared to other regions and counties in order to study its sustainability and energy usage.The electricity use of Yanbian was just 7.847% of its total energy use,and was 39% and 33.19% that of American and Japan, respectively.The index of emergy sustainable development was 19.45,which indicated that its economy was in the period of under development.Meanwhile,the environmental loading was only 0.627, indicating abundant resources with high economic development potential.Suggestions for the sustainable development of Yanbian ecological-economic system were put forward.
