摘　　要：从能值的角度出发,以宁夏移民区代表区域红寺堡移民开发区2007年统计数据与调查数据为基础,对该区种植业生态系统的能值投入与产出进行首次分析。建立了由环境承载率、净能值产出率、能值投入率和可持续发展指数等构成的评价指标体系,并与同类地区和一些发达地区进行了对比分析,结果表明:该区种植业生态系统能值投入以不可更新的工业辅助能为主,尤其以化肥为主,能值投入率、净能值产出率相对较低,环境承载率较高,对环境的压力很大;可持续性发展指数很低,属于消费型经济系统。基于红寺堡移民开发区种植业系统能值分析的特点,提出了促进系统可持续发展的对策建议。The initial analysis about the energy inputs and emergy outputs of plantation ecosystem from the perspective of energy in immigrator area of Hongsibu,the representative area of Ningxia immigrator area was carried out based on the statistical and survey data of 2007 in this area.The evaluation index system consisting of environmental load ratio,the net emergy yield ratio,emergy investment ratio,and sustainable development index was established.Compared with the similar area and some developmental areas,the analysis showed that the investment of energy in this area was mainly from the non-renewable industrial auxiliary energy,especial fertilizer.The comparatively lower ratio of energy investment and the net energy yield,and higher load ratio of environmental caused great pressure on the environment.The low index of sustainable development in this plantation belongs to consumer-oriented economic system.Based on the above characteristic of energy analysis of this area,the paper puts forward the strategies and suggestions for promoting the sustainable development of system.
