AN ANALYSIS OF RURAL SETTLEMENT PATTERNS AND THEIR EFFECT MECHANISMS BASED ON ROAD TRAFFIC ACCESSIBILITY IN POVERTY ALLEVIATION AREA
The distribution of rural settlements is an important manifestation of man-land relationship in spe-cific regions.Exploring the distribution of rural settlement space in the mountains is an important basic work that reveals the regional characteristics of the rural human-land relationship system in the mountains.This paper is based on Shaanxi Province in the south section of Qinba Mountains as a typical case area.It uses ras-ter cost weighted distance,geographical spatial analysis,accessibility and geographical detectors to system-atically analyze the characteristics and influencing factors of rural settlement space in the mountains of Yangxian County.The results show that:the accessibility of Yangxian County has obvious spatial difference,which shows the zonal distribution characteristics extending along the traffic roads.Mountainous rural settle-ments distribution has significant low elevation and clustering orientation.Yangxian rural settlements are mostly distributed in low-level southern and low-level areas in the south,showing the agglomeration distri-bution trend.The absolute number and relative proportion of the countryside have gradually increased with the improvement of the level.In the regional system of mountainous areas,natural conditions such as eleva-tion,slope,precipitation,and temperature,as well as education and medical treatment are the key factors af-fecting the distribution of rural settlement space in the research area.
