Evolution of Rural Settlement of Russia Pattern Based on GIS:A Case Study of the Fenwei Plain in the Middle Reaches of the Yellow River
Taking the fenwei plain in the middle reaches of the Yellow River as an example,using the methods of single dynamics,Landscape Index,nuclear density analysis and buffer zone analysis,the evolution of rural settlement of Russia patterns in the fenwei plain in the middle reaches of the Yellow River over the past 30 years was studied.The results show that the scale of rural settlement of Russia land in the fenwei plain has gradually expanded in the past 30 years,and experienced a process from diversification to monoculture and then to agglomeration and diversification.It is mainly found in and around Xian,Weinan,Taiyuan,Yuncheng and Luoyang,and has become a core area of population and economic development.In terms of geographical conditions,the rural settlement of Russia are mainly concentrated in plains and gentle slopes with an elevation of less than 800 m and a slope of less than 12°,and are distributed along roads and rivers.The evolution of rural settlement of Russia is influenced by geographical conditions,policies and economic interests,leading to changing spatial patterns,with natural topography,transport,economic levels and ecological policies being the main factors.
