摘  要:定量重建近百年来中国城市用地规模数据集是历史LUCC的重要内容,基于新挖掘的晚清和民国时期利用现代测绘技术完成的军事地形图资料,格网化重建和测度了中国传统农区17个省区1910s城市用地规模和城市体系特征。研究结果表明,研究范围内县级以上城市用地规模总和为1812. 149km~2,平均值为1.215km~2,变异系数为2. 338。城市用地规模最大的直隶为236. 054km~2,最小的广西为43. 003km~2。全部1022个格网中共计745个有城市用地,其中最大值为65. 236km~2、最小值为0. 068km~2。城市规模分布呈现北部高、南部低,东部高、西部低的特点,无城市分布的格网主要集中在川西和云南西部。总体的城市体系分形维数q=0. 729,R~2=0. 882,具有较好的分形结构特征。热点分析显示,共有6个城市聚集区超过了90%置信度水平,其中三个一级聚集区为京津地区、直隶南部和鲁豫交界区、苏浙皖地区;三个二级集聚区为关中平原、成都平原和珠江三角洲地区。聚类分析结果显示,全部省区的城市体系可以分为三类:广西、山东、湖北、福建、湖南、江西、云南、安徽、浙江、山西为第一类,河南、四川、陕西、广东、贵州为第二类,直隶和江苏为第三类。Quantitative reconstruction of urban land-use datasets in recent 100 years is an important part of the historical LUCC. Based on the newly discovered military topographic maps completed during the late Qing and the Republic of China,by using modern survey and mapping techniques,grid reconstruction and measurement of1910 s urban land use and urban system characteristics in 17 provinces of China ’s traditional agricultural regions were conducted. The results of the study indicate that the total urban land in the study area was 1812. 149 km~2,with an average value of 1. 215 km~2 and a coefficient of variation of 2. 338. The largest urban land was 236. 054 km~2 for Zhili,and the smallest was 43. 003 km~2 for Guangxi. Among all 1022 grids,745 were urban lands,of which the maximum was 65. 236 km~2 and the minimum was 0. 068 km~2. The distribution of cities showed the characteristics of high in the north,low in the south,high in the east and low in the west. The grids without cities were mainly concentrated in western Sichuan and western Yunnan. The overall urban system fractal dimension q = 0. 729,R~2= 0.882,had a good fractal structure characteristics. The hotspot analysis showed that 6 urban agglomerations exceeded the 90% of confidence test. Among them,three primary agglomeration areas were the Beijing-Tianjin area,the southern area of Zhili and the Shandong-Henan area,and the Jiangsu,Zhejiang,and Anhui areas. The three secondary agglomeration areas were the Guanzhong Plain,the Chengdu Plain,and the Pearl River Delta. The cluster analysis results shoed that the urban systems of all provinces and regions could be divided into three categories:Guangxi,Shandong,Hubei,Fujian,Hunan,Jiangxi,Yunnan,Anhui,Zhejiang,and Shanxi belonged the first category,Henan,Sichuan,Shaanxi,Guangdong,and Guizhou belonged the second category,Zhili and Jiangsu were the third category.
