摘要
内蒙古自治区地处我国北部边疆,区内地貌类型多样,地质环境条件较为复杂,自然因素和人为活动诱发了大量的崩塌、滑坡、泥石流等地质灾害,严重危及了人类生存的环境,在一定程度上制约了自治区的经济建设与发展。在收集已有资料的基础上,经过分析总结,归纳出自治区地质灾害的种类、分布范围及危害程度。同时依据地质灾害专项调查成果,在综合考虑地形地貌、岩土体类型等地质环境背景条件的基础上,采用比拟法,对全区的地质灾害进行了灾害易发区划分,并针对内蒙古地质灾害状况与分布,提出了防治的基本指导思想和原则。最后,依据地质灾害易发程度分区,按照“以人为本”的原则,结合国土资源的重要性,划分出重点防治区,提出了相应的防治对策。
Inner Mongolia Autonomous Region is located in the north of China, where kinds of physiognomy are diversified and geologic environment is comparatively complicated. Geo-hazards such as collapse, landslide and debris flow etc. caused by natural factors and human activities have seriously threatened the human living environment and restricted the economic development of Autonomous Region. This paper presented the sorts, distribution and harmfulness of the hazards in Inner Mongolia drawn from the data collection and analysis. At the same time, the zonation of geo-hazards was divided by analogy, according to the investigation of regional geo-hazards and topography, physiognomy, rock-soil type. The basic guiding ideology and principle of geo-hazards prevention were put forward by considering the distribution of geo-hazards. Finally, based on the principle of ＂man is important＂ and the importance of territory resources, the control measurements were proposed for the major geo-hazards prevention zones.
