山东省城市土地集约利用时空差异

Analysis of Temporal and Spatial Difference on Regional Urban Land Intensive Utilization:A Case Study of Shandong

结合山东省区域发展实际,从土地利用强度、土地利用投入和土地利用效益等方面出发构建区域城市土地集约利用综合评价体系,以山东省地级城市的土地利用数据为基础,采用主成分分析法、聚类分析法对省内区域城市土地集约利用水平进行综合评价,分析其时间和区域变化情况,为宏观指导城市土地资源集约利用、转变土地利用方式提供参考。研究结果表明:(1)2000-2005年山东省城市土地利用集约度不断提高,而2006年比2005年山东省城市土地集约利用度稍有下降;(2)山东省城市土地集约利用水平从沿海城市向内地递减,尤其以山东省西南部边缘城市集约度水平最低;(3)经济发展水平是影响土地集约利用重要的外部因素,济南和青岛等经济发达地区集约利用水平相对较高。

This paper tried to explore the comprehensive evaluation system of regional urban land intensive utilization from land use intensity, land use investment, land use benefit,etc. Based on the actual conditions, using principal component analysis and clustering analysis, this paper made comprehensive evaluation on the intensive land-use level of Shandong Province, analyzed the changing situation in space and time, provided reference for macro guidance in urban land intensive use and changing land use pattern. The results showed： （1） The level of urban land intensive use of Shandong Province constantly improved from 2000 to 2005, while decreased a little in 2006; （2） the level of urban land intensive use declines from coastal cities to inland cities, with the southwest cities having the lowest level; and （3） economic development level is the most important external factor affecting the level of urban land intensive use. The level of urban land intensive use is higher in developed areas, like Jinan and Qingdao, than other areas.
