- Abstract:
-
In order to reveal the spatiotemporal evolution characteristics and influencing factors on rural settlements in hilly region of southern Henan Province in the process of urbanization, spatial autocorrelation analysis and local linear geographically weighted regression were used to analyze aggregation characteristics of the rural settlements and their driving factors. The results show that rural settlements of Guangshan were aggregated in north and central of the county, and its affecting factors show strongly non-stationary across spatiotemporal scales; in different regions, the strength and intensity of the effects were different; in year of 1985, the distribution of rural settlements was affected by geographical and geomorphic factors, and traffic factors which included altitude, distance to nearest river, distance to nearest county, distance to nearest national road and distance to nearest provincial road; by year of 2015, the strengthen of geographical and geomorphic factors effect on rural settlements distribution reduced; meanwhile, beside previous factors(i. e. altitude, distance to nearest national road and distance to nearest provincial road), other new factors i. e. rate of urbanization and density of rural households had shown significantly effects on density of the settlements. Suitable altitude, convenience roads, high rate of urbanization and density of rural population can increase the density of rural settlements.
