江西省土地利用空间格局重建研究——基于1820年和1980年数据的对比分析

The Study on the Reconstruction of Historical Land Use Spatial Distribution of Jiangxi Province——Based on the Comparative Study of 1820's and 1980's Data

在查阅历史文献基础上,采取治所邻近度分析、适宜性评价等方法重建江西省1820年1 km×1 km空间格网下的主要地类空间分布,并将重建后的1820年土地利用数据和1980年土地利用现状数据进行比较分析.研究结果表明:重建结果通过了显著性检验,这表明重建结果较为合理;1820年江西省耕地、城镇用地、农村居民点用地、水域及其他土地面积分别为29 228、105、1 648、3 730、134 227 km^2,其中耕地主要分布在吉安、建昌以北的鄱阳湖平原区,城镇用地及农村居民点用地分布则较为零散,主要分布于河流两岸及河流交汇处;从1820—1980年,江西省土地利用空间格局未发生大的改变,但受人口增长的影响,全省城镇用地、农村居民点和耕地的面积分别增加了364、462、16 276 km^2.

Based on historical documents,a variety of metliods has been used to reconstructed the land use spatial patem of Jiangxi Province in 1820 witli a spatial grid of 1 km x 1 km,such as administrative legacy proximity analysis,suitable evaluation,etc.Furtliermore,a comparative analysis has been made between the reconstruction results and the modem land use data of Jiangxi Province in 1980.Results show that t!ie regression results pas the significance test,which indicates that the reconstruction result is reasonable.is reasonable.The area of cropland urban land,rural residential land,water body and otiier land of Jiangxi Province in 1820 are 29 228,105,1 648,3 730,134 227 km2 respectively.Cropland is mainly distributed in the Poyang Lake plain,north of Ji’an,Jianchang prefecture.Compared with cropland,the urban land and rural residential land are more fragmented and mainly distribute in the river bank and the confluence of river.river.From 1820 to 1980,the land use spatial distribution of Jiangxi Province has not changed drastie.But influenced by the immigration inceased in Jiangxi Province make a great contribution to quantity growth of the urban land,rural residential land and cropland,the growth number of the urban land,rural residential land and cropland are 364,462,16 276km2 respectively.
