Based on the spatial analysis technique, statistic analysis of GIS and landscape ecology theory, the author studied the distribution characteristics and influencing factors of rural settlements in village regions as a case of Qianjin Village of Shizhu County with the major data sources of the second national land survey (including contour line, river, road and rural settlements) at the scale of 1:2000. The results showed that rural settlements land areas were scattered sites in disorder at present, and main influencing factors included the degree of slope, inconvenient water, road accesses, and the distance from cultivated land.
