摘    要:为了对山西省农业生态系统进行更加有效的调控与管理,本文应用能值分析方法,对1980-2008年山西省农业生态系统的演替轨迹进行了研究。结果表明:(1)山西省农业生态系统生产效率有了十分显著的提高。(2)山西省农业生态系统在获得经济输入能值上处于劣势。(3)山西省农业生态系统环境负载率将会长期居高不下。(4)山西省农业生态系统的发展越来越依赖于工业辅助能值的投入。进一步提高系统生产效率的途径在于提高农业现代化装备和技术,同时加大农业剩余劳动力的转移力度。

Abstract:In order to adjust and manage Shanxi ago-ecological system more effectively, based on emergy methods, the developing regular and trend were explored in Shanxi Agro-ecological system from 1980 to 2008. Following is the conclusion: (1) Production efficiency has been improved largely. (2) The system lies in inferior position in getting economic emergy. (3) Environment loading ratio will still be high in the future. (4) Developing of Shanxi agro-ecologieal system depend on input of industry emergy more and more. The way to improve production efficiency of the system should be adjusting emergy input structure and improving agro-modernization equipment and technology, and transferring unnecessary labour from agriculture to 6ther industry.
Keywords:Shanxi Province  agro-ecological system  emergy analysis
