中文摘要：

经济、社会和生态系统的协调有序发展是地区可持续发展的重要基础,文中以甘肃省崇信县为例,构建经济-社会-生态复合系统的指标评价体系,然后采用耦合度、发展度、耦合协调系数和灰色关联度分析经济、社会和生态系统的协调发展关系。研究发现：生态子系统得分最高,社会子系统和经济子系统较低,全县始终为经济滞后型的发展类型;耦合度明显高于发展度和耦合协调系数,反映了崇信县的经济、社会和生态三个子系统的协同发展水平较好,而综合发展水平欠佳的局面。经济系统中经济规模是社会水平和生态水平的主要驱动因素,社会系统中居民生活水平和公共服务事业对经济水平和生态水平具有支撑作用,而生态系统中工业污染和治理是制约经济水平和社会水平的主要因素。总体而言,由于社会进步、经济结构的调整及生态环境的治理,崇信县经济-社会-生态复合系统的发展更为平衡、协调,研究结果对于欠发达地区探索经济-社会-生态系统的协调发展模式具有一定的借鉴意义。

英文摘要：

The coordinated development of economy,society and ecology is the important foundation for sustainable development. Taking Chongxin county as an example,we constructed an index system of economy-society-ecology system,and analyzed the coordinated development relationship among economic,social and ecological environment system using the coordinated degree,development degree,coordinated-development degree and grey related degree. Results showed that the score of ecological system was the highest,and the scores of the social and economic system were comparatively low,and the developmental type of Chongxin county belonged to economy lagged all the time. The coordinated degree was higher than development degree and the coordinated-development degree in 2010 ~ 2015,which revealed the high degree of coordinated development of the social,ecological and ecological environment system and the low degree of comprehensive development. The grey relationship showed that economy scale in economic system was the driving factor for society and ecology development,and the residential living standard and public service career in social system played a supporting role in economy and ecology,and the industrial pollution emission and control was the main constraint of economy and society. In short,because of social progress,adjustment of economic structure and the governance of ecological environment,the developmental level of economy-society-ecology system was far more balanced and coordinated. The results had a certain referring significance for the economy-society-ecology coordinated development of undeveloped areas.
