摘 要:根据清代文献中有关城垣周长里数及政区设置的记载资料,探求估算清代城镇用地面积的可行性、估算方法、资料处理与转换方法以及偏差校正方法等,初步取得了一套反映清代嘉庆年间(1820年) 本部18行省城镇用地面积的估算数据。在此基础上,分析该区城镇用地规模的区域差异,并与1999年调查统计资料进行对比。Based on the numerable and standardized data collected from historical documents, we reckoned the areas of urban land use for 18 provinces in the Qing Dynasty, analyzed the changing situation, regional differentiation, and contrasted them with those of the contemporary age. The results are shown in the following: (1) The method, by which the areas of urban land use in the Qing Dynasty are reckoned in light with at the administrative division levels, the number of towns and city wall perimeters, was provided with rationality to a certain degree. (2) The results showed that the area of urban land use was 1,987.44 km2 in 18 provinces of the Qing Dynasty, merely 0.05% of the total land area in the region. Among which the scopes of Zhili and Jiangsu provinces were the greatest, being 316.34 km2 and 185.77 km2, respectively 0.097% and 0.188% of the jurisdiction area, and Guangxi and Guizhou provinces were the smallest, 27.92 km2 and 32.78 km2, respectively (only 0.012% and 0.033% of the jurisdiction area). (3) There were obvious spatial differences in urban land use in the region. For the scale of urban land use, the northern provinces were greater than the southern provinces, the eastern provinces were greater than the western provinces, and southwest provinces were the smallest in all the provinces. The provinces of Zhili, Shaanxi, Sichuan, Jiangsu and Zhejiang were obviously greater than the other provinces.
