汶川震区山洪泥石流灾害危险性评估
Hazard Assessment of Mountain Torrent Debris Flow in Wenchuan Seismic Area
摘要
Abstract
The main factors inducing mountain torrent were classified into two types:stable factors which have rela-tive stable role in the mountain torrent development,and complex factors which vary greatly before and after the earthquake.The distribution patterns of different factors were mapped and the impact degree of each factor on disas-ter pattern was quantified by using stepwise regression and AHP.Finally,the diagram of risk distribution of moun-tain torrent debris flow in the seismic area was obtained by using overlay analysis function of ArcGIS.The assess-ment system of this study is demonstrated to be well applicable compared with previous similar research results.It could be intuitional reference for the prevention of mountain torrent debris flows in seismic area.关键词
