摘要:

针对当前历史土地利用空间重建研究多基于单一地类且空间分辨率较低的特征,提出较高分辨率全地类土地利用空间重建方法。以1820年为时间断面,以现代江苏省域为研究区,以历史文献记载、历史地理学研究成果、现代统计数据、自然环境数据等为支撑,将土地利用类型划分为耕地、聚落用地(含城镇用地、农村居民点用地)、水域和其他用地(含林草地及未利用地),考虑区域自然资源和社会经济特征,提出理论假设,对府级耕地、城镇用地、农村居民点用地数量进行修正;沿用以现代土地利用格局为基础反演历史土地利用格局的基本思路,从人地关系角度出发,采用治所邻近度分析、综合评价等方法重建了1820年100 m×100 m空间格网下的江苏省土地利用格局,同时,通过不同地理分区统计及降尺度对比间接验证等分析了重建结果。结果表明:① 1820年江苏省耕地、城镇用地、农村居民点用地、水域用地及其他用地面积分别占区域总面积的48.49%、4.46%、0.16%、15.03%和31.86%;② 1820年研究区内土地垦殖率较高,但建设用地比率较低,受人口分布、地形及河网密度等影响,不同地理分区土地利用差异较为显著;③ 农村居民点用地及耕地的降尺度分析结果均呈显著线性正相关,在一定程度上表明研究结果具有合理性。

Abstract:

Reconstructing the spatial data of historical LUCC could fill the gap between modern remote sensing interpretation results and long-term LUCC change analysis, and promote the study of spatiotemporal dynamics of land use and its impacts on climate and ecology. The current studies has obtained certain achievements and revealed the spatial pattern of historical LUCC to some extent. However, the results were normally in the form of single land use type and low spatial resolution. Thus, this study targeted to propose an integrated method of land use reconstruction with relatively high spatial resolution. We set 1820 as the time section and took the administrative boundary of contemporary Jiangsu Province as the study area. Supported by historical documentary records, historical geography research results, modern statistical data and natural environmental data, we divided the land use types into cropland, settlement (including urban land and rural residential land), water body and other lands (including forest, grassland and unused land). Considering the characteristics of regional natural resources and socioeconomic conditions, theoretical hypotheses were proposed to obtain the areas of cropland, urban land and rural residential land at prefectural level. Based on the modern land use pattern, from the perspective of man-land relationship, the land use map of Jiangsu Province in 1820 with a spatial grid of 100 m×100 m was established by administrative seat proximity analysis, integrated suitability indices analysis and so on. Then, statistics of different geographical divisions and comparative analysis of data in sub-regions were used respectively to analyze and validate the results indirectly. The results showed that: (1) In 1820, the area of cropland, urban land, rural residential land, water body and other lands of Jiangsu Province accounted for 48.49%, 4.46%, 0.16%, 15.03% and 31.86% of the total study area respectively. (2) The land use pattern in Jiangsu Province has general features of higher cultivation rate and lower construction rate. Meanwhile, affected by the discrepant population distribution, topography and drainage density, land use in different geographical divisions varied significantly. (3) The proportion of the area of residential land and cropland at county level occupying the correspondent city level in 1820 and 1985 showed a significant positive linear correlation. Therefore, the results of this study had certain reasonability and could provide methodological references for related historical LUCC reconstruction.
