Abstract:

The quantitative reconstruction of historical urban land use and urbanization level data sets can make contribution to good simulation of the environmental effects of land use and cover change. In this study, urban land use and city patterns above or within the county level in Jiangxi Province during the Republican era are reconstructed with the aid of the ArcGIS platform on the basis of the military map during the Japanese invasion of China. A comprehensive data set, which contains the city wall perimeter, urban land area, non-construction land in the city wall, and construction land outside the city wall, is obtained. The data set with a 10% error based on the comparison with detailed data from other studies can be applied to land use models of various historical periods. The county-scale level of land urbanization is analyzed. The "farmland-inside-city" phenomenon occurred in 20 cities, which accounted for 25% of the total number of cities in Jiangxi. The "urban-outside-city" phenomenon is found in 28 cities, which accounted for 35% of the total number of cities in the province. The result shows that the overall area of urban construction was 87.99 km2, which accounted for 0.053% of Jiangxi's total area. The overall urbanization rate of Jiangxi during the Republican era was 0.047%. Of all the cities and counties in the province, Nanchang had the highest urbanization rate (0.19%), whereas Suichuan reached only 0.007%. The urbanization level was positively correlated with the population (r = 0.457, P < 0.001). The data sets of urban land use and urbanization in Jiangxi can provide land use data for relevant global environmental change models.

Key words: Republic of China period, Jiangxi Province, urban land use, urbanization level, land use and cover change
