摘 要:晋陕蒙接壤地区能源资源优势明显,开发规模大,特殊的气候与地质地貌条件使其成为中国水土流失最严重的区域。在资源开发过程中如何兼及社会和生态共同发展,成为制约该区域科学发展的瓶颈。选取该地区典型区域榆林市经济、社会、生态方面22个指标,用熵权法确定各指标权重,依据层次分析原理构建区域系统协调评价模型,测算协调发展指数,发现该市的协调度指数呈先降后升的"U"型变动规律,表现为广义的环境库滋涅茨规律,而发展度和协调发展度指数先缓慢后加速上升,影响协调性的关键因素是生态系统发展滞后,促进研究区域协调发展的主要对策是加强生态基础设施建设。The contiguous area of Shanxi, Shaanxi and Inner Mongolia of China is very rich in energy resources which are in development of high strength. At the same time the unique topography and climate conditions make it the most serious soil erosion region in China with much environmental and ecological sensitivity. How to make soci- ety and ecology systems develop together with rapid economy development and avoid the usual path of so-called 'first development with pollution then control' is a problem which restricts the scientific development in this region. So, this paper chooses 22 indicators of economy, society and ecology systems to set up an index system (better choose relative indexes or the per capita indexes and account by changeless price to get more accurate analysis re- sults), and then collects data information from statistical yearbook of Yulin City, Shaanxi Rrovince in 2010(which contains the newest data until 2010, published by Yulin Bureau of Statistics in Shaanxi Province, 2011 ), after that determines their cost weights by entropy weight method to calculate comprehensive development scores of each sys- tern. Then based on the principle of the model of coordinated development above model in China, with which accounts the hierarchical analysis, this paper the previous research findings of originally builds up a new mathematical urban and rural coordinated development coordinated development degree and then analyzes the changing trend fea- tures combining with the regional conditions. At last, the result of this research shows that each one of economy, soci- ety and ecology systems had an unbalanced development progress, while the percentage of important indicators in economy system was 50.0%, in society system was 22.2%, in ecology system was 60.0%, and that 1995 was a very important time point in the development process of this area, after 1995 the development degree (index k1 ) of com- posite systems came into a rapid growth stage while before 1995 it increased slowly. But the regional
