摘要
为了定量分析宁夏生态经济系统的发展水平及其可持续发展状况，运用能值理论对2010--2015年宁夏生态经济状况进行分析。结果显示：2010--2015年间宁夏生态经济系统总能值使用量由148．75×10 2 sei增加至208．67×10 21 sej，在总能值使用量中93％以上为不可更新资源能值，说明宁夏生态经济的快速发展取决于对本地不可更新资源的开发和利用；宁夏生态经济系统的能值自给率高达97％以上，而其外部输入能值却严重不足，对本地不可更新资源的开发和利用虽使经济得到发展，但长此以往必将导致不可持续的发展；宁夏生态经济系统的环境负荷率较高，经济发展对生态环境的压力较大。
In order to quantitatively analyze the development level of Ningxia eco-economic system and its sustainable development level, the eco-economic situation of Ningxia from 2010 to 2015 was analyzed by emergy analysis. The results show that the total energy consumption of Ningxia eco-economic system is increased from 148.75× 10 21 sej to 208.67 × 10 21 sej from 2010 to 2015, and the total energy value can not be renewed in the total energy use value of about 93%. It shows that the development of Ningxia ecological economy is mainly based on development and the use of local non-renewable resources to achieve; Ningxia eco-economic system of emergy self-sufficiency rate of up to 97% or more, and its external emergy serious shortage of local non-renewable resources development and utilization of the economy, although the development of the past leading to unsustainable; Ningxia eco-economic system of environmental load rate is higher, the economic development of the greater pressure on the ecological environment.
