- Abstract:
-
In order to reveal the spatio-temporal evolution characteristics and influencing factors of rural settlements in karst areas, based on the landscape pattern index method, the change of landscape pattern of rural settlements in Pingguo City and Baise Pingguo City, Guangxi Province during 1989—2017 was analyzed, and the dominant factors affecting the evolution of rural settlements were explored by using geographically weighted regression model from natural and location factors respectively. The results thow that:(1)the scale of rural settlements in Pingguo increased significantly from 1989 to 2017, and the area and quantity of rural settlements increased by stages;(2)karst villages were different from non-Karst villages in terms of size, distribution and morphology; karst villages were more fragmented, more complex and had higher scale and aggregation degree;(3)elevation and slope hadthe most significant influence on rural settlements in the study area. The scale of rural settlements in karst villages increased obviously, and the degree of aggregation was enhanced. The spatial and temporal evolution pattern was greatly affected by natural geographical factors. For the non-karst villages, river, road and other factors had the greater impact on the spatiotemporal evolution of rural settlements.
