重庆市喀斯特槽谷地区农村居民点分布与地貌形态要素关系研究
Research on the distribution of rural settlements in relation to landform factors in karst trough valley of Chongqing Municipality
摘要
Abstract
Taking rural settlements of Tuanjie Village, Yunchi Town, Shizhu Tujia Autonomous County as the study case, distribution characteristics of rural settlements are analyzed in view of landform factors such as elevation, slope, aspect, terrain undulation, surface roughness, SOA(slope of aspect) and SOS(slope of slope) . The study adopts the method of spatial analysis and geostatistics of GIS and applies frequency distribution index of landform - area and information entropy. The major results indicate the advantageous terrain habitats of rural settlements locate in areas with elevation 956. 2-1 000 m, slope 5-15 degree, aspect SW, W, NW and E, terrain undulation 0-1 m, surface roughness 1. 0-1.1, SOA and SOS 0-5 degree. The maximum of information entropy of rural settlements in the bottom of karst trough valley is 1. 15, but the minimum is 0. 02, which indicates that the orderliness of rural settlements distribution in the low terrain is higher.关键词
