【摘要】 康定县地处四川盆地西缘山地及青藏高原过渡地带。县域内地势险峻,地形切割强烈,地层与地质构造复杂,新构造运动强烈,地震活动频繁。加之降水充沛,致使山地灾害十分发育,其中滑坡灾害占山地灾害的38.32%。通过搜集资料及现场调查,概述了该县县域内滑坡灾害的分布;从行政区划、自然地理及灾害规模等3方面统计分析了滑坡灾害的发育现状;从地形地貌、地层岩性、地质构造、降雨、地震活动、人类工程活动等方面总结了滑坡灾害的形成条件,并提出防治对策与措施,力求有效地预防与减少滑坡灾害的发生。更多还原

【Abstract】 Kangding County is located in the transition area between the west hilly edge of Sichuan Basin and the Tibetan Plateau.In this field,steep topography,fierce landform incision,complex strata and geological structure,intense neotectonic activity,frequent earthquakes and heavy rainfall caused many geological hazards.Landslides account for 38.32% of the geological hazards.Based on investigation data in the county,the authors analyze the landslide distribution characteristics of in the county.The development status of the landslides is statistically analyzed using administrative area,natural geography and disaster scale etc.Also according to the terrain and physiognomy, strata and lithology,geological structure,rainfall,earthquake and mankind activities,the formation conditions are presented.Based on statistical data,the principle of landslide disasters control and corresponding countermeasures are put forward in order to reduce the loss of the landslide disasters.更多还原
