大理市生态经济系统协调度研究.pdfVIP

摘要 以大理市生态经济系统为研究对象，根据区域生态经济系统的特征把 它分成生态环境、经济社会两个子系统， 过构建评价指标体系，基 于协调度模型，建立了关于区域生态经济系统协调度评价的指标范畴 。研究表明：2009~2010年经济社会与生态环境发展关系处于低度失 调，而2010年后开始转入弱度协调。面前大理市仍然存在经济相对落 后、生态恶化、生态经济协调发展水平和层次较低等问题，为此需要 进一步开展生态经济系统改良，提高生态经济发展水平，以实现生态 建设经济发展人民富裕的预期目标。 [关键词] ：生态经济系统；协调度；功效函数；权重 Abstract To the Dali ecological economic system as the research object, according to the characteristics of regional ecological economic system it is divided into two sub- systems: ecological environment, social economy, by building the evaluation index system, based on coordination degree model, to establish the coordination degree of regional ecological economic system evaluation index. Research shows that: the development of social economy and ecological environment from 2009 to 2010 in relationship in low imbalance, and began to turn to weak after 2010 degrees of coordination. In front of the Dali remain relatively backward economy, ecological deterioration, ecological coordinated economic development level and the level is relatively low, so need to be further conducted ecological economic system reform, improve the ecological economic development level, to achieve the anticipated target of the peoples rich ecological construction economic development.
