【摘要】 黄土洞穴是晋西黄土高原地区发育的一种特殊微地貌景观和地质灾害。在野外调查基础上,详细总结了晋西黄土洞穴的分布情况及发育特征,研究表明:晋西黄土洞穴发育密度沿万荣-隰县-离石-兴县一线由南向北呈递增趋势,而发育深度受地层构造、岩性及其厚度、地形等多因素的综合控制;黄土构造节理的产状与黄土洞穴的产状基本一致,对洞穴形成影响显著;黄土洞穴内部构造特征多样化,反映了黄土洞穴不同时期的演化特征。更多还原

【Abstract】 Loess cave is a kind of special micro-geomorphology and geological hazard in the Loess Plateau of west of Shanxi province.Based on the field survey,this paper summarizes the distribution of loess caves and the characteristic features.Researches show the characteristic density of loess caves increase by degrees with Wanrong-Xixian-Lishi-Xingxian conuty in west of Shanxi province.The combined function of various factors controls the characteristic depth,including layer,loess quality,depth,topography and so on.The tectonic joints of loess have great influence on loess caves formation,its attitude and loess caves attitude being consistent.The interior tectonic feature that is diversification reflects the different evolution characters.更多还原
