Abstract: Taking rural residential in Yujiang County as study object， the spatial distribution characteristics and influencing factors were explored by VCM curve， kernel density estimation method， spatial autocorrelation analysis， Voronoi diagram， topographic index and so on. It was shown that the distribution of rural residential in Yujiang County belonged to cluster type. The high value of rural residential concentrated in the central plains area. The main factors influencing the rural residential distribution pattern consisted of topographic index， slope aspect， geological disasters， water loss and soil erosion， road， drainage， town. The rural residential concentrated to the topographic index advantage area， slope aspect advantage area， road developed area， drainage superior area and urban area. The geologicalhazardprone area， topographic index and slope aspect disadvantage area exhibited little appeal to rural residential. For the advantage region with a lot of rural residential， it could be used as the key developmental area， and reasonable planning and guidance should be provided for the construction of such area. While， for the disadvantage region with little rural residential， such as Huaqiao Town， Huangzhuang Village， Tangchaoyuan forest farm and so on， preventive measures and relocation work should be done.
