基于DEAHP模型的区域生态经济系统可持续发展评价

为了解区域生态经济系统的可持续发展能力,结合区域生态经济系统的内涵及内部结构特征构建了对应的DEAHP模型及评价指标体系.进一步,对2007—2012年间我国省际及三大区域生态经济系统的可持续发展水平进行评价.研究结果显示,近年来我国生态经济系统的整体有序度水平呈单调递增趋势,但整体有序状态仍处于相对低下水平.从区域来看,东部与西部的差异相对较大,而相邻区域之间的差异相对较小.从省域来看,相邻省份之间的差异相对较小,省际生态经济系统的有序发展与地区经济发展程度存在明显的正相关关系.研究表明,DEAHP模型的构建从理论上为评价区域生态经济系统的可持续发展能力提供了一种研究范式,为我国区域生态经济系统的可持续发展提供了一定的理论和实践指导.

Sustainable Development of Regional Ecological Economic System Based on the DEAHP Model

To understand the sustainable development ability of a regional eco-economic system, this paper constructed a DEAHP model and an evaluation index system by combining the connotations and characteristics of the internal structure of a regional eco-economic system. Furthermore, we evaluated the sustainable development level of both provincial and regional eco-economic systems from 2007 to 2012 in China. The results showed that the degree of the overall order in China increased monotonically and was relatively low. In addition, the results show that, for the three regional eco-economic systems in China, the eastern region differs remarkably from the western region but two neighbouring regions are relatively closer. The results are very much the same at the provincial level. Also, at the provincial level, the sustainable development ability of a provincial eco-economic system is positively correlative with the development of local economy. This paper presents a feasible research framework, which uses a DEAHP model to evaluate a regional eco-economic system and provides theoretical and practical guidance for the sustainable development of regional eco-economic system in China.
