| 肃北蒙古族自治县是河西走廊地质灾害最为发育的县区之一。本文以肃北县地质灾害详细调查项目为依托,通过实地测量、调查评价和综合研究等手段,在概述县域自然地理条件及地质背景的基础上,阐述了县域内已有的地质灾害特征和类型,即该县地质灾害以泥石流为主、崩塌次之。从地形地貌特征、气象水文、地层岩性、地质构造等方面入手分析了地质灾害的发育特征,并探讨了地质灾害的形成条件及发育规律,为研究河西走廊地质灾害的发育特征、形成条件、发育规律提供重要参考,为县域地质灾害防灾减灾提供科学依据。 |
| 英文摘要: |
| The Subei Mongol Autonomous County is one of the most developed geological hazards in Hexi Corridor. On the basis of detailed investigation of geological hazards in Subei Mongol Autonomous County, Jiuquan, through field survey, investigation, evaluation and comprehensive research, and on the basis of a brief description of the physical and geographical conditions and geological background of the county, this paper expounds the characteristics and types of geological disasters existing in the county, that is, the main geological disasters in the county are debris flow, followed by collapse. This paper analyzes the development characteristics of geological hazards from the aspects of topography and geomorphology, meteorology and hydrology, strata and lithology, and geological structure, and probes into the formation conditions and development laws of geological hazards, it provides an important reference for studying the development characteristics, forming conditions and developing rules of geological disasters in Hexi Corridor, and provides scientific basis for preventing and reducing geological disasters in County. |
