摘要
能值理论是综合分析生态经济系统的各种能量流的转换机理,并定量研究生态效益与经济效益及其相互关系的重要理论。本文以柴达木盆地(青海海西州)的农牧生态经济系统为例,通过一系列的能值指标的建立和能值的投入产出分析,定量分析海西州农牧业生态系统的特点,并发现该地区农牧业生产中存在的问题,从而为本地区和相似区域农牧业的可持续发展提供科学依据。
energy theory offered by Odum H. T was applied widely to track energy flow and evaluate ecological and economic benefits in eco -economic system. Based on the energy theory, this research quantitatively analysised the characteristics of farm - stock - raising ecosystem in the Qaidam Basin （ Haixi Prefecture in Qinhai） by establishing main indices. According to the energy input - output analysis, the problems existed in the Qaidam Basin were found, and scientific guidance for the sustainable strategy of the basin and similar regions were provided.
