华北平原典型区县农村聚落的时空演变及影响因素分析
Rural Settlements Spatio-temporal Evolution of Typical Districts and Counties in the North China Plain and the Influence Factors Analysis:A Case Study of Shanghe County,Jinan
摘要
Abstract
In order to explore the spatio-temporal evolution characteristics and influence factors of rural settlements in the North China Plain,tak-ing Shanghe County of Jinan City as the research area,based on multi-temporal Landsat images,we extracted the time series spectral features and texture features,used random forest algorithm,spatial analysis,kernel density analysis,spatial autocorrelation analysis and other methods to classify the rural settlements in Shanghe County,and discussed the spatio-temporal evolution of rural settlements in Shanghe County in recent 20 years and its influence factors.The results show that the classification process in this paper has high classification accuracy,with an average over-all accuracy of 90.06％and an average Kappa coefficient of 0.876 4.In the past 20 years,the spatial density of settlements presented a distribu-tion pattern of"dense in the northwest,northeast and southeast,sparse in the southwest,and increasing high-density areas".The degree of spa-tial agglomeration is negatively correlated with the density.Rural settlements always maintain the pattern of agglomeration distribution,but the agglomeration degree is weakening.The number and scale of rural settlements show the characteristics of decreasing to both sides,with rivers and roads as the center.Extracting rural settlements and spatio-temporal evolution analysis are of great significance for optimizing the spatial pat-tern of rural settlements in Shanghe County and promoting the overall development of urban and rural areas.关键词
