| 摘 要： | 利用多时相,多平台卫星遥感数据,对四川省泸定县磨西台地的地质灾害开展了遥感监测.研究了地质灾害的发展演化趋势,判定了地质灾害的稳定性,为磨西台地的地质灾害防治提供了科学依据.遥感监测显示,自2006年1月2日至2009年12月21日的近4 a,磨西台地内无新发生泥石流和崩塌灾害,原已发生的泥石流和崩塌也未见明显复发,泥石流处于停歇期,崩塌处于稳定状态.大部分滑坡处于稳定状态,只有1处新发生的滑坡还在发展之中,处于不稳定状态,存在进一步发展的可能,需进一步加强监测.磨西台地岸坡的冲蚀滑塌和浅层流滑则一直在持续发展,对磨西台地岸坡的稳定构成威胁,并造成磨西台地面积的缩小,需要及时治理.

| Abstract: | The remote sensing monitoring of geological hazards on the Moxi Platform in Luding County,Sichuan Province,China,was carried out using remote sensing data from the multi-temporal and multiplatform satellite.Evolution trends and stability of geological hazards were obtained,and a scientific basis for prevention of geological hazards was provided.Results from the remote sensing monitoring reveal that during the period of nearly four years from January 2,2006to December 21,2009,new debris flows and avalanches did not occur at the platform,which means that there were no recurrence of debris flows and avalanches,debris flow were intermittent,and avalanches and most of landslides were in a steady state.There was only one new landslide still in developing and precarious state,which is subject to further development and needs to be monitored.Slides and collapses induced by river erosion and shallow debris flow on margins of the Moxi Platform are always developed continuously,which will threaten the stability of bank and reduce the area of the platform and hence needs handling at early date. |
