基于能值分析的宁夏各市生态经济系统研究

摘要

利用能值分析法对宁夏各市的生态经济系统进行对比研究.结果表明,宁夏各市的生态经济发展的空间差异明显;在经济上极大地依赖本地资源,环境负载率较高,对环境造成严重污染.宁夏各市应在优化产业结构,提高资源利用效率的同时,加大招商引资和对外开放的力度,合理开发旅游资源,以增加外部能值输入的比率,从而不断提高自身的可持续发展能力.%Emergy analysis was used to analyze the ecological economic system of cities in Ningxia.The results showed that the spatial differences in the development of ecological economy in Ningxia were obvious.The economy was highly dependent on local resources and the environmental load rate was high,which causes serious pollution to the environment.The cities of Ningxia should optimize the industrial structure,improve the efficiency of resource utilization at the same time,increase investment and opening up efforts,the rational development of tourism resources to increase the external energy input ratio,and continuously improve the cities' sustainable development capacity.
