内蒙古奈曼旗畜牧业系统能值变化分析

Energy Analysis of Stockbreading System in Naiman Banner

运用能值理论对内蒙古奈曼旗的畜牧业系统进行了分析,在分析能值投入结构的基础上,分析并对比了1980、2000年一系列能值指标的变化。通过能值分析得出:1980年奈曼旗畜牧业系统对环境资源有较强的依赖性,随着畜牧业的发展,用以维持畜牧业系统运转所需的能值输入减少;虽然各类资源的利用效率有所提高,但仍处于低水平;充分利于种植业的产品,延长畜产品的生产链条是未来畜牧业发展的有效途径。

Stockbreading system of Naiman Banner was analyzed using the energy theory. On the basis of analyzing the energy input structure, a series of energy indices of 1980 and 2000 were assessed and compared. Research results showed： in 1980, stockbreading system deeply depended on the environmental resources. With the development of stockbreading, energy input which maintained the performance of stockbreading system decreased. Though the use efficiency of all resources improved more or less, but still stayed in a low level. It was an effective way to promote stockbreading development by making full use of cropping industry products and extending industry chain.
