山东省城市土地经济密度时空差异分析

Analysis on Time and Space Differences of Shandong Urban Land Economic Density

基于山东省17个城市的土地经济密度数据,利用变差系数、相对发展率分析等方法,初步探讨了2005—2014年山东省城市土地经济密度的动态演化格局及区域差异特征。研究结果表明:山东省各城市土地经济密度均呈现上升趋势;土地经济密度原本较高的城市,其土地经济密度相对发展速度也较快,各城市相对发展速度呈现不同;济南和青岛的增长极效应显著,带动周边城市经济效益提升;城市土地经济密度的主要影响因素包括自然因素、经济因素和政策因素,具体包括城市区位、城市交通状况、城市产业结构和城市土地投入等方面。

Using the coefficient of variation analysis, the relative development rate and other methods, this article discussed the dynamic evolution of the urban land economic density pattern and characteristics of regional difference from 2005 to 2014 preliminarily based on the land of 17 cities in Shandong province economic density data. The results showed that:(a) From city to city in Shandong province the land economic density tended to rise.( b) The city with higher economic density previously, its land in relative economic development speed was faster, and the cities presented different development speed relatively.( c) The growth pole of Jinan and Qingdao effected significantly, drove around the city's economic benefit.( d) The main factors influencing urban land economic density included natural factor, economic factor and policy factor. The specific location, included city urban traffic, urban industrial structure and urban land investment, etc.
