吉林西部开垦初期的LUCC类型空间分布重建——基于GEOMOD模型

Reconstruct the Spatial Distribution of Land Use / Land Cover in the Early Reclaimed Time of the Western Jilin Province—Based on the GEOMOD model

百年尺度上的土地利用/覆被变化研究是全球土地系统变化和土地利用变化研究的主要内容,开垦初期的LUCC研究也必不可少,但是其数据来源较少,获取困难。该研究依据土壤类型、坡度、20世纪30年代的人口数量以及距居民点距离对耕地分布的驱动影响,在GEOMOD模型中输入20世纪30年代的耕地数量、20世纪50年代的耕地与非耕地空间分布图,从而模拟出20世纪30年代的耕地与非耕地空间分布图,同时也生成了一个耕地分布的适宜性图。该方法重建了当时的耕地空间分布,其重建结果比较理想,具有一定的参考意义。

Centennial-scale land use and land cover change research is the main content of the global land system change and land use change research, the land use and land cover change research in the early reclaimed time is essential, but the data sources is fewer, and access to diffi- cult. Based on the impact of soil type, slope, population in the 1930s＇ and the distance from the settlements on arable land, we enter the amount of cultivated land in the 1930s＇ , arable land and non-arable land space maps in the 1950s＇ into GEOMOD model, and simulate a 1930g arable land and non-cultivated land space maps, but also generates an arable land distribution suitability map. The model reconstructs arable land spatial distribution, the reconstruction results are ideal, so this model has a certain reference significance for other studies.
