本文运用能值分析方法定量分析了内蒙古生态经济系统1990-2005年间的发展态势,结果表明:内蒙古经济系统的可持续发展指数由1990年的873.43下降到2005年的11.88,同期人均能值使用量在快速增长,分别由1.13×1016sej上升到2.54×1016sej,环境负载率也由0.58上升到4.21,能值自给率都高达98%以上。这说明内蒙古的经济还处在欠发达阶段,并且经济的快速发展是建立在对本地资源的过度依赖和高强度利用基础之上的,因此可以说内蒙古经济在一定程度上是不可持续的。有鉴于此,应从以下方面提高内蒙古的可持续发展能力:(1)大力开发可再生资源,促进人与自然和谐发展;(2)优化对外贸易结构,提高能值受益率;(3)抓好煤炭城市经济结构调整与合理布局;(4)加强高科技和教育投入,提高系统可持续发展潜力。
In this paper, we use the method of emergy analysis to quantitatively analyze the development trend of eco-economic system in Inner Mongolia from 1990 to 2005. The results show that the index of sustainable development of Inner Mongolia’s economic system dropped from 873.43 in 1990 to 11.88 in 2005, In the rapid growth, from 1.13 × 1016sej to 2.54 × 1016sej, the environmental load rate also rose from 0.58 to 4.21, and the self-sufficiency ratio of energy value was as high as 98%. This shows that the economy of Inner Mongolia is still underdeveloped, and the rapid economic development is based on over-reliance on local resources and high-intensity utilization. Therefore, it can be said that Inner Mongolia’s economy is not sustainable to some extent. In view of this, Inner Mongolia’s capacity for sustainable development should be enhanced in the following aspects: (1) vigorously develop renewable resources and promote the harmonious development between man and nature; (2) optimize the structure of foreign trade and raise the rate of return on energy; and (3) do a good job Economic restructuring and rational distribution of coal cities; (4) Enhancing investment in hi-tech and education so as to increase the potential for sustainable development of the system.
