中文摘要：

基于统计数据，我们分析了并且评估为从 1983 ～ 2014 跨越的时期在 Yanchi 县联合和 eco 经济的系统的协作的度。eco 经济的系统能被划分成社会经济、生态的分系统，他们的关系能揭示在二个分系统之间的相互作用州并且帮助本地政府建立一个协调发展模式。一个索引系统被构造在联合和协作的度的评估前估计二个分系统的开发。主要部件回归分析被采用到份量上在联合和 eco 经济的系统的协作的度上估计自然、经济、社会的因素的影响。结果证明从 1983 ～ 2014，两个分系统的发展趋势与有更多的变化的生态的分系统正在增加。在学习区域联合和 eco 经济的系统的协作的度从 1983 ～ 2014 逐渐地增加了，但是从混乱的边缘经历了五个不同开发阶段到有利协作。本地社会、经济的条件的发展是影响联合和协作的度的最重要的因素。第二个很重要的因素是从本地政府的金融支持。另外，环境保护政策也起了不能否认的作用。由于影响因素的差异，政府应该采取全面措施支持 eco 经济的系统的持续发展。

英文摘要：

Based on the statistical data, we analyzed and evaluated the degree of coupling and coordination of the eco-economic system in Yanchi County for the period spanning from 1983 to 2014. The eco-economic system can be divided into socioeconomic and ecological sub-systems and their relationship can reveal the interaction state between the two sub-systems and help the local government to establish a coordinated development mode. An index system was constructed to assess the development of the two sub-systems before the evaluation of the degree of coupling and coordination. The principal component regression analysis was adopted to quantitatively assess the influences of natural, economic and social factors on the degree of coupling and coordination of the eco-economic system. Results showed that, from 1983 to 2014, the development trends of both sub-systems were increasing with the ecological sub-system having more fluctuations. The degree of coupling and coordination of the eco-economic system in the study area increased gradually from 1983 to 2014, but experienced five different development stages from the verge of disorder to favorable coordination. The development of the local social and economic conditions was the most important factor influencing the degree of coupling and coordination. The second most important factor was the financial support from the local government. In addition, the environment protection policies also played undeniable roles. Due to the diversity of the influence factors, the government should take comprehensive measures to promote the sustainable development of the eco-economic system.
