摘要:

区域生态系统对人类生产生活有直接或间接的影响,从产业视角探究其发展状况对实现可持续发展有重要意义。本文运用能值方法对西南山区典型县域——兴文县2005—2011年间社会、经济、环境状况做了详细分析。结果表明:兴文县发展重心由农业转向工业和旅游业;社会子系统发展较快,对此,工业和旅游业有最突出贡献;经济发展较快,但仍处于较低水平,经济模式粗放;产业的社会、经济和环境功能相互独立。总体而言,兴文县社会和经济发展状况较好,但日益增大的环境压力挑战着当地的可持续发展。

Abstract: Sustainability of regional ecosystem influences human production and life directly and indirectly. In order to promote regional sustainable development, it is necessary to explore the development trends of different industries in a region. This paper aimed to investigate the development trends of society, economy and environment of Xingwen County, a mountainous region in southwestern China from 2005 to 2011 by applying emergy analysis. The results showed that the social subsystem developed rapidly, and the pillar industries of Xingwen County transformed from agriculture to industry and tourism. Meanwhile, the rapid development of the industry and the tourism also incurred an increasing pressure on the local environment. The functions of economy, environment and society of the three industries were relatively independent of one another. In a word, the society and economy of this county developed relatively well; however, the rising environmental pressure challenged its sustainable development.
