Analysis on spatial distribution of rural settlement and population pressure in Huanren County

Based on RS, GIS and statistical analysis, this paper discusses the relationship of rural settlement spatial distribution and topography, landform, soil erosion, economic development, as well as achieves the classification of population pressure in Huanren County in Eastean Mountain Areas. The results show that the distribution pattern of rural settlement is affected obviously by elevation, slope, soil erosion and economic level, and population pressure is great and uneven.
