Abstract:: This paper, studying on the spatial distribution of different rural settlements, can provide significant reference for immigrant relocation project, integration of rural settlement distribution and intensive utilization of land. Based on the second land survey data and SRTM-DEM, and by using average nearest neighbor index (ANNI), kernel density estimation (KDE), exploratory data analysis (EDA) and ‘hotspot’ analysis, the characteristics of the spatial distribution of rural settlements and its influential factors in terms of natural environment and social economic conditions were studied. The results show that the distribution of rural settlements has an ‘arched and layered’ structure and marks difference of the spatial distribution and scale in Ningqiang County, big plaques are mainly in river terrace and low mountain areas, high density, small plaques and low intensive land use were influenced by the dominant factor—terrain. Rural settlements can be classified into three types by the principles of suiting one’s measures to local conditions: positive development, internal potential tapping and strange land relocation. The study results can provide reference for the construction and development of the small cities and towns.
