层次分析法在滇西怒江河谷潞江盆地段崩塌与滑坡地质灾害危险性评价中的应用

The application of analytic hierarchy process to the danger evaluation of collapse and slide in Lujiang basin segment of Nujiang valley, western Yunnan Province

  • 摘要: 以外动力地质灾害相对多发的滇西怒江河谷潞江盆地段为研究对象,基于该区的1∶5万地质灾害调查结果,在全面掌握该区崩塌与滑坡分布状况的基础上,利用层次分析法对该区地质灾害危险性程度进行综合分析和评价,获得了该区的崩塌和滑坡危险性评价图。可将该区崩塌和滑坡的危险性划分为稳定、基本稳定、不稳定3个等级的区域,稳定区主要是高黎贡山自然保护区,部分基本稳定和不稳定区域主要分布于人类活动相对频繁的地区。
    Abstract: In this paper, based on a comprehensive investigation of the distribution condition of the collapse and slide in this area and utilizing the results of 1∶50000 geohazards survey of this area, the authors studied the Lujiang basin area in Nujiang valley, western Yunnan Province, where the exterior dynamic force relatively frequently causes geohazards. A comprehensive analysis and evaluation of the danger degree of geohazards were carried out with the analytical hierarchy process (AHP). The authors have drawn the risk assessment map for this area, and divided the hazards of collapse and slide in this area into three levels, i.e., stable, basically stable and unstable. The stable area is distributed in Gaoligong Mountain natural reserve, and the basically stable and unstable areas are mainly distributed in the region where human activities are relatively frequent.
