Study On Spatial Form Of Valley Plain Rural Settlement In Loess Gully Area Of Northern Shaanxi

The Loess gully Area in northern Shaanxi is the most representative natural geographical unit in the Loess Plateau.The ravines in the region crisscross and the terrain is complex,taking the landform as the main carrier of rural settlement.Due to its unique geographical environment,it is difficult for the rural settlements in the gully area to follow the same rules as other regional rural settlements to seek development.Different types of rural settlements will have obvious regional characteristics and regional differences in the spatial distribution form,presenting different spatial form characteristics.In recent years,with the continuous development of urbanization,rural has also entered a new period of development and transformation,rural settlement in loess gully area also carried out the development according to local conditions,and gradually realized the sustainable development of rural settlement.This paper takes the plain rural settlement of the loess valley in northern Shaanxi,as the object of the study.Firstly,the paper analyzes on the basis of the relevant theoretical analysis on the characteristics of the rural settlement,laying the foundation for the study of the main river.Secondly,the On the basis of the rural settlement research on the main stream of the Yanhe River,Based on the research purposes,The upper,middle,upper,middle and lower sections of the main River,The factors affecting the rural settlement space and the spatial distribution characteristics in different main stream sections are discussed;Further,According to the analysis of the present situation,The rural settlements with the largest number of main stream sections and with typical characteristics are divided into four types according to the plane form and settlement internal spatial structure: point diaspora,band settlement,cluster intensive and fan agglomeration,Combined with the specific rural settlement,the detailed analysis of its spatial form,The spatial form of the Yanhe River is derived;Finally,the,The spatial optimization and development of rural settlement in this area,The overall optimization idea for the shortcomings of rural settlement space,As well as the relevant suggestions and strategies for the development of different types of rural settlement space.To a certain extent,this research has perfected the existing research content of the specific types of rural settlements in the loess gully area of northern Shaanxi,and also provided ideas for the optimization and development of this type of rural settlement space.It is hoped that through the analysis of the loess gully area in northern Shaanxi,which has unique geographical environmental characteristics,it can provide guidance for the development of the same or similar rural settlement space,so as to realize the optimization and sustainable development of the settlement space units.
