基于能值分析的株洲农业生态经济系统综合研究

Integrative study of Zhuzhou agro-ecosystem based on emergy analysis

运用能值分析方法,对株洲市2001-2008年农业生态系统的能值投入产出、运行效率、ELR、ESI进行定量分析,构建能值指标体系.结果表明:株洲农业生态系统主要依赖于人力,尚处于从传统农业阶段向现代农业阶段转变的过渡时期;研究区农业生态经济负载率低,资源环境压力在逐渐加大,资源空间利用未达到优化配置.为促进株洲农业的可持续发展,应根据农业的需要合理调整农业产业结构,使农业生态经济系统可持续发展.

Based on energy analysis, the paper studied the value of the input-output status operation efficiency, and used quantitative analytical method to study ELR and ESI in Zhuzhou from 2001 to 2008. The results showed that the agro-ecolomic system in Zhuzhou still stayed in the period from traditional to modern agriculture, which mainly depended on man power. Zhuzhou had a low ELR, with increasing pressure-state- response, and the resources were not fully developed. To promote the sustainable development of agriculture in Zhuzhou, the structure of agriculture to achieve sustainable development of the agro-eeonomic system should be gradually adjusted.
