Emergy evaluation and sustainable development of ecological-economic system-case study of Yanbian in Jilin Province

Abstract

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.

Key words: Human disturbance, Soil property, Soil microbe, Secondary forest area, Loess Plateau
