鄱阳湖地区农业生态系统能值分析

Emergy Analysis of Agro-ecosystem in Poyang Lake Area

运用能值分析理论与方法,对鄱阳湖生态经济区农业生态系统的能值投入产出情况、可持续发展状况进行了定量分析。结果表明,相对于全国平均水平,该地区的环境负载率较低,净能值产出率较高,可持续发展能力较强。根据能值分析的结果,提出了立足现有丰富的自然资源,加大科技投入,发展循环农业,促进农业可持续发展的对策。

By using emergy analysis theory and methods,we conduct quantitative analysis on the input and output of energy,and sustainable development of agro-ecological system in Poyang Lake Area.The results show that compared with the national average,the environmental loading ratio is relatively low in this area;the net energy yield rate is high;the sustainable development ability is strong.Finally according to the results of energy analysis,corresponding countermeasures are put forward as follows： develop agriculture based on the existing rich natural resources;increase technological inputs;develop circular agriculture;promote sustainable agricultural development.
