Abstract:
The methods of ArcGIS spatial analysis, nearest neighbor analysis, kernel density estimation and regression analysis are used to study the spatial and temporal distribution characteristics of rural settlements and its influencing factors of Huangling County in Weibei Upland, and reconstruction ideas were put forward for different residential areas, based on the remote sensing images in 2000, 2010, 2015 and DEM data.The main results showed that the number and area of rural settlement patches increase firstly and then decrease, with obvious characteristics of stage change of Huangling County. The rural settlements have obvious spatial agglomeration characteristics, and the agglomeration scope is constantly expanding. The layout of rural settlements has a strong dependence on topography, rivers and roads. At the same time, factors such as population and economic development, industrialization and urbanization, and policy control have increasing influence on the layout of rural settlements. The spatial reconstruction of rural settlements should be based on the objective conditions and functions of all kinds of residential areas. Scattered residential areas in ecologically fragile areas should pay attention to ecological migration. Reserved residential areas should improve the level of intensive land use. Central residential areas should strengthen their hub effect of connection and serve the urban and rural areas.
