【摘要】：资源环境是制约区域发展的重要影响因素,区域资源环境的利用是否有效是衡量地区综合发展水平的关键指标之一。因此对区域资源环境效率格局及其成因机理进行时空动态模拟,不仅有助于人们了解区域投入产出的过程与效益,同时又能为相关部门制定区域发展规划以及缓解区域人地矛盾提供参考依据。利用SBM-DEA模型分析2005~2014年间中部地区资源环境效率时空分异特征,并探讨了造成其格局演化的成因机理,得到如下结论:(1)从资源环境效率结果来看,2005~2014年中部地区资源环境效率总体呈现稳步上升态势;(2)省会城市、长江和京广等国家发展轴线的重要节点城市资源环境效率较高,远离长江、京广等重要轴线的城市资源环境效率较低的空间分布格局逐步形成;(3)从资源环境效率与投入产出的耦合关系来看,中部地区75%左右的城市处于Ⅰ类型,较少城市处于Ⅱ类型,极少数城市处于Ⅲ~ⅩⅢ类型。近10 a来中部地区普遍处于低投入、低产出、低污染的发展阶段,资源环境效率较高及以上城市数量先减少后增加,中等效率的城市数量先增加后趋于稳定,效率较低及以下的城市数量呈逐步减少的趋势;(4)促进资源环境效率的主导因素为地区经济发展水平,制约资源环境效率的主导因素为能源消耗。
[Abstract]:Resources and environment are important factors restricting regional development, and whether the utilization of regional resources and environment is effective is one of the key indicators to measure the level of regional comprehensive development. Therefore, the temporal and spatial dynamic simulation of the efficiency pattern of regional resources and environment and its formation mechanism is not only helpful for people to understand the process and benefits of regional input and output. At the same time, it can provide a reference for the relevant departments to formulate regional development planning and alleviate the contradiction between people and land in the region. The SBM-DEA model is used to analyze the temporal and spatial differentiation characteristics of resource and environmental efficiency in the central region from 2005 to 2014, and the genetic mechanism of its pattern evolution is discussed. The conclusions are as follows: (1) from the results of resource and environmental efficiency, From 2005 to 2014, the overall efficiency of resources and environment in the central region showed a steady upward trend. (2) the urban resources and environment efficiency of the important nodes of the development axis of the provincial capital cities, the Yangtze River and Beijing-Guangzhou countries are higher, and the spatial distribution pattern of the low efficiency of urban resources and environment far away from the important axis of the Yangtze River and Beijing-Guangzhou is gradually formed; (3) from the point of view of the coupling relationship between resource and environment efficiency and input-output, about 75% of the cities in the central region are in type I, less cities are in type II, and very few cities are in type III ~ X III. In the past 10 years, the central region is generally in the stage of low input, low output and low pollution. The number of cities with high and above resource and environmental efficiency decreases at first and then increases, and the number of cities with medium efficiency increases at first and then tends to be stable. The number of cities with low efficiency and below shows a trend of decreasing gradually. (4) the leading factor to promote the efficiency of resources and environment is the level of regional economic development, and the main factor restricting the efficiency of resources and environment is energy consumption.
