- Abstract:
-
Based on the spatial and temporal distribution information of rural settlements which was extracted from Landsat TM/OLI and ETM+ remote sensing image in 1987, 2001 and 2016 by using visual interpretation, and using GIS spatial statistical analysis and landscape index and other research methods, we analyzed the spatial pattern and spatial difference of rural settlements of the Shiyang River Basin in 1987, 2001 and 2016. The results indicate that the scale of rural settlements in the research area shows an expanding trend and the characteristics of scale expansion are significant; the scale difference of rural settlements is obvious, showing the larger the pattern scale of distribution is, the smaller the proportion of patches is, and high-density distribution of small patches and low-density large-scale distribution of different characteristics; the spatial distribution pattern of rural settlements has not changed obviously during 1987-2016, which is the spatial characteristics of low altitude, small slope and near water resources, but the trend of local agglomeration is further strengthened, and the rivers and the cities’ surroundings are the more obvious areas of agglomeration of the rural settlements; the patch complexity of rural settlements is weakened and the fragmentation degree is reduced, and the shape tends to be regular; however, the spatial difference of patch morphology is obvious; the differentiation trend of the patches is intensified due to the expand of patches.
