中文摘要：
通过构建EES系统协调发展指标,采用变异系数协调发展模型,以1997-2011年榆林市12个县（区）为研究的时空范围,对其协调发展程度进行测算与评价.研究结果表明：从时间维度上榆林市EES系统协调发展整体态势好转,协调类型的转变速度加快,处于逐步调和阶段,并且与经济发展呈现正相关关系;从空间格局分析,EES系统协调发展县际差异显著,形成中心地带和南北两端三个等级板块,呈现由分散到集中、由核心到边缘的空间格局.基于评价结果,提出调整产业结构,转变经济发展方式等对策.
英文摘要：
This thesis establishes a coordinated development index system of ecotogy, economy and society and coordinated development coefficient of variation model. By studying the coordinated development degree in 12 counties and districts in Yulin from 1997 to 2011, research results are ： （ 1 ） In terms of time, the overall situa- tion of coordinated development of ecology, economy and society is improving, and the transition of coordinaCOO the types is speeding up. It is still in the stage of harm rdinated development degree of ecology, economy an analysis of space, the author finds it unbalanced in onic phase. It d society and coordinated has shown economic development a positive correlation between development phase. （2） From degree in Yulin. The coordinated development of regional EES system is significantly difference, forming the three grade plate of heartland and the north and south ends; it presents the structure from decentralization to centralization and the core -edge. Based on the evaluation results, it puts forward corresponding countermeasures.
