陕南秦巴山区地质灾害发育及空间分布规律
Development and Spatial Distribution of Geological Disasters in Qinling-Daba Mountains of South Shaanxi
摘要
Abstract
To further study the development and spatial distribution regularities of geological hazards in Qin-ling-Daba Mountains of south Shaanxi, probability statistics analysis on quantity, scale, material composition, etc of the geological disasters in the region is done.Results show that the major types of the hazards are accumulated layer landslides while rock collapses secondary.Landslides are mainly small shallow and isometric ones while col-lapses small and isometric ones.Spatial dot densities of the geological hazards have “four high two low” distribu-tion, while collapses“three high four low”and debris flows“three high two low”.The special distribution of haz-ards, faults, rivers and roads have fractal characteristics.There are power-law correlations between areas and vol-umes ( lengths, widths) of the landslides ( collapses) , and the areas and volumes are of logarithmic normal distri-butions.The results provide technical support for the selection of relocation sites for immigrants in this region.关键词
