Analysis and Evaluation of Multi-Scale Spatial Characteristics of Rural Residential Areas
This paper puts forward a method to analyze the spatial distribution characteristics of rural residential areas from three scales of＂whole region,block and plot＂,and three dimensions of ＂scale feature,agglomeration degree and spatial form＂.The experiment takes Changxing county as the research area,extracts multi-scale rural residential boundaries by using U-net neural network model,and analyzes and evaluates the distribution characteristics of residential areas by using four area indicators,kernel density estimation,hot spot analysis and shape index analysis.The results show that:(1)On the scale of the whole area,the study area is a land-inten-sive area,and the homestead land is close to the local minimum standard.(2)At the block scale,the area attribute of rural residen-tial areas in the study area shows obvious＂cold hot spot＂ characteristics.(3)At the plot scale,the residential areas in the study area are mainly strip-shaped,scattered and block-shaped,and the overall map area is large and the spatial pattern is relatively regular.
