- Abstract:
- The spatial pattern of rural residents and its dynamic changes are conducive to the consolidation and optimization of residential areas, and to promote the intensive use of rural land use. Tongyu County in the west of Jilin Province was selected as the study area in this paper, GIS technology and spatial analysis model were used for quantitative analysis of the temporal and spatial variation and the evolution of spatial patterns of Tongyu County in 1955, 1990 and 2013 rural residents, and factors affecting the characteristics of rural residential land layout were analyzed in-depth by selecting the landscape pattern index. The results showed that residential areas gathered in the order: 1955 > 1990 > 2013. At the spatial scale of 45 km, three periods of residential areas gathered to the maximum extent, which indicates that the aggregation degree of the residential area increased at first and then decreased with the increase of spatial scale. Landscape elements such as slope, road and waters have a significant impact on the layout of rural residential land in Tongyu County. With the increase of slope and the distance from the road and the water bodies, the number of patches of the rural residential areas has varying degrees of reduction. The change of population was consistent with the change of residential area in 1955—2013. Population expansion is an important reason for the expansion of the residential area. This study can provide decision-making basis for the spatial layout of rural residential land, and provide the application reference for the new rural construction, increase or decrease hook, and the comprehensive improvement of rural land.
