摘要

生态经济评价是城市可持续发展领域的重要组成部分,通过定义生态经济发展指数(EDI)及其计算方法,构建省域尺度生态经济发展水平定量分析的指标体系,指标包括23项,内容涉及农林业经济产值、林业生态建设、水土保持治理、城市废弃物处理等。应用主成分分析法对贵州省2011—2015年的生态经济状况进行定量评价。结果表明,贵州省2011—2015年生态经济发展指数分别为0.093、0.323、0.427、0.660、0.860,生态经济发展可持续性增强。文中根据生态经济发展评价结果,进一步在生态环境改善、经济潜力发展、社会资源利用等方面进行了区域排序,研究认为,贵州省应从发展山地特色农业、加强水土保持治理、落实林业生态红线方面促进生态经济健康发展。
        Ecological economy evaluation is an important part in the field of urban sustainable development. The index system for quantitative analysis of eco-economic development at provincial scale was constructed by defining the ecological economy development index and its calculation method, which included 23 items, covering agricultural and forestry economic output, forestry ecological construction, water and soil conservation, and urban waste management.The quantitative evaluation for the ecological economy of Guizhou Province in 2011-2015 by the principal component analysis showed that the ecological economy development index from 2011 to 2015 in Guizhou were 0.093, 0.323, 0.427, 0.660 and 0.860, and the sustainability of eco-economic development was enhanced. Based on the evaluation results of eco-economic development, this paper further ranked the regions in terms of ecological environment improvement, economic potential development, and social resource utilization, etc., and concluded that the healthy development of ecological economy should be promoted in Guizhou by developing characteristic agriculture in mountainous areas,strengthening soil and water conservation management,and implementing the ecological red line of forestry.
