| 摘 要： | 以中国336个地级以上城市为研究对象,利用核密度估计和探索性空间数据分析方法,对2001~2014年中国地级以上城市土地经济密度差异的时空格局演化及影响因素进行分析和探讨。结果表明：① 中国地级以上城市土地经济密度的总体水平不断提高,平均值从2001年的4.769亿元/km2增加至2014年的15.375亿元/km2,但地区差距逐渐扩大;② 中国地级以上城市土地经济密度表现出显著的全局空间正相关性,相邻地市相互影响,呈现出“高–高”或“低–低”的空间集聚态势,且从LISA集聚图来看,城市土地经济密度通过空间聚类可以划分为“高水平均质型地域”、“塌陷型地域”、“极化型地域”和“低水平均质型地域”4种类型,不同地域类型的空间分布范围和稳定性等都存在差异;③ 中国地级以上城市土地经济密度冷、热点区域的空间分布具有相对稳定性,总体上表现出“东热西冷”的分布格局,热点区主要分布在东部的京津冀地区、长江三角洲地区和珠江三角洲地区等,广大中、西部地区则大多处于低值簇,属于城市土地经济密度的冷点区或次冷点区;④ 自然条件状况决定城市土地的供给能力和开发潜力,是导致中国地级以上城市土地经济密度差异的基础性因素,区域经济发展水平、经济发展政策、土地利用管理政策也会对城市土地经济密度差异造成一定程度的影响。 |

| Abstract: | Taking 336 cities across China as research subject, this study employs Kernel Density Estimation (KDE) and Exploratory Spatial Data Analysis (ESDA) to analyze and discuss the spatial-temporal evolution and influencing factors of urban land economic density disparity in prefecture-level cities of China from 2001 to 2014. The results show that: ① Urban land economic density in prefecture-level cities of China increases, the average value increased from RMB 47.69 million per km2 in 2001 to RMB 1.5375 billion per km2 in 2014, with increasing regional disparity. ② Urban land economic density in prefecture-level cities of China displays significant global positive spatial autocorrelation, and neighboring cities interrelate, showing the spatial agglomeration of "high- high" or "low-low". From the LISA map, the spatial cluster of urban land economic density can be divided into high level and equally regional type, type of collapse, type of polarization and lower level and equally regional type, while the stability of the spatial distribution of various clubs are differ. ③ Cold spots and hot spots of the urban land economic density in prefecture-level cities of China distribute stably, showing the pattern of "hot east and cold west" on the whole, hot spots mainly lie in Beijing-Tianjin-Hebei region, the Yangtze River delta and the Pearl River delta; While most middle and west regions locate in the low value cluster, belonging to the cold spots or second cold spots of urban land economic density. ④ Natural conditions determines the supply ability and development potential of urban land, which is the basic factor for the disparity of urban land economic density in prefecture-level cities of China. Additionally, the level of regional economic development, the policies of regional economic development and land use management also have a certain influence on the disparity of urban land economic density. |
