山西省生态经济可持续发展时空差异研究

Study on Spatial and Temporal Differences of Sustainable Development of Ecological Economy in Shanxi Province

实现生态经济可持续发展是资源型城市社会经济发展的必经之路.本文运用能值理论,评价2011年―2016年山西省生态经济可持续发展程度,并对其进行时空差异分析.研究结果表明:(1)山西省不可更新资源能值占总能值的70%以上,环境负载率大于10,生态环境压力大,并且各市间能值指标差异性较大;(2)山西省生态效率指数低,空间差异性由60.01%上升为83.61%,呈非均衡分布发展,吕梁、阳泉和忻州是山西省生态效率的"洼地";(3)山西省可持续发展指数介于2~5之间,表明生态经济系统存在着巨大的可持续发展潜力,主要包括太原、大同、临汾和晋城;(4)山西省生态经济系统可持续发展的空间趋势由"中心向四周递减"演变为"四周高、中间低".

Achieving sustainable development of ecological economy is the essential way for the socio-economic development of resource-based cities.This paper uses energy value theory to evaluate the degree of sustainable development of ecological economy in Shanxi Province from 2011 to 2016,and analyzes the spatial and temporal differences.The results show that:(1)Energy value of non-renewable resources in Shanxi Province accounts for more than 70%of the total energy value,the environmental load rate is greater than 10,the ecological environment pressure is large,and the energy value indicators of different cities are different;(2)The ecological efficiency index is low,and the spatial difference increases from 60.01%to 83.61%,showing a non-equilibrium distribution.Lvliang,Yangquan and Xinzhou are the"squatting places"of Shanxi’s ecological efficiency;(3)The sustainable development index is between 2 and 5,indicating that the ecological economic system has great sustainable development potential,including Taiyuan,Datong,Linfen and Jincheng;(4)The spatial trend of the sustainable development of the ecological economic system has evolved from"the center to the periphery"to"four-high and low in the middle".
