标题：URBAN AND RURAL SETTLEMENTS PATTERN CLASSIFICATION AND DISTRIBUTION ENVIRONMENT IN HUNAN PROVINCE BASED ON COUNTY SCALE ECOLOGICAL CIVILIZATION, CHINA
摘要：Based on the land data and satellite images of Hunan Province, the spatial distribution environment characteristics of urban and rural settlements pattern elements in Hunan Province are quantitatively analyzed by using the methods of spatial data analysis, nuclear density statistics, transect correlation, grid coupling measure and so on. The regional types are further divided according to the overall construction guidelines of ecological civilization. The results showed that Hunan Province is divided into 7 geomorphological areas. There is a negative correlation between elevation and water area. There is a one-to-one effective connection relationship between county and expressway, township and provincial highway. Hunan settlements show the spatial distribution pattern of the largest continuous accumulation patch in the middle hills, the second in the northern lake area and the southern high hill area, and the small and scattered patches in the surrounding mountainous basin. Cultivated lands and settlements show the pattern characteristics of coupling distribution. It is formed into three basic domain types: dotted, banded and concentrated block. Finally, the pattern of urban and rural settlements in Hunan Province is divided into 8 types: water network block, landscape block, multinuclear belt, continuous radial, binuclear zone, one nucleus and multi-point, multi-point dispersion and continuous strip type. This study is beneficial to the sustainable and healthy development of ecological environment and civilization construction in the county.
