| 摘 要： | 基于能值分析的区域性可持续发展评价指数为基础,计算了1983~2003年泰来生态经济系统的可持续发展指数。结果表明:泰来净能值产出率较高,环境和资源系统的负载率有所增加,受净能值产出率和环境负载率变化趋势的影响,泰来生态经济系统的可持续性呈现总体下降的趋势。

| Abstract: | Taking regional sustainable development appraisal index on the basis of energy analysis as a foundation,this article has calculated the sustainable development index of eco-economy system in Tailai from 1983 to 2003.The result indicates that: net energy yield radio is higher,load factor of environment and the resources system,to some extent,has increased,and sustainability of eco-economy system presents downward trend influnced by net energy yield radio and the load rate of environment. |

| Keywords: | energy analysis eco-economy system sustainable development |
