Abstract:: Based on the distribution index and information entropy, we discussed the distribution characteristics of rural residential land of Wushan County on 6 Landform factors on different gradients of elevation, slope, aspect, terrain, slope of slope and variation coefficient in elevation. The influence of landform factors on the distribution and development of rural settlements was quantitatively studied by variable fractal theory. The Results showed that advantageous terrain habitats for rural settlements were characterized by the elevations of 250~1 000 m, slopes with gradients of 0°~25°, aspects of SE, S, SW and NW, terrain undulation of 0~30 m, slopes with change of 0°~9°, variance coefficient in elevation of 0~0.02. The orderly degree and distribution pattern of rural settlements showed a high correlation degree, and the order degree was higher in dominant terrain. The relationship between rural settlements and elevation, terrain undulation, slope change and variance coefficient in elevation fitted the second-order accumulated variable dimension fractal distribution, while the slope and aspect fitted the first-order and third-order, respectively. Thus the influence degree of these landform factors on rural settlements followed the order: slope > elevation > slope of slope > terrain undulation > variance coefficient in elevation > aspect.
