| 英文摘要 | Field observation, remote sensing combined with GIS technique were adopted to analysis thespatial distribution characteristics of secondary geological disasters induced by Wenchuan earthquake.The study results show that: (1) The earthquake-damaged slash mostly distributed in the two sides ofmain fault zones, earthquake-affected areas and disaster density decreased with the increase of distance from the main fault. (2) The earthquake-damaged slash mostly distributed in seismic intensity of IX and above. The region with greater seismic intensity had larger disaster density. Collapse and landslidedistributed in high seismic intensity zone. (3) Hard rocks were easily caused secondary geologicaldisasters by seismic waves. (4) The earthquake damaged slash mostly distributed within 0.5 km away fromthe river and decreased with the increase of distance from river. Collapse and landslide often appear at valley and the steep slope which more than 40 degree. The biggest hazard density appeared at altitude between 2000 m and 2500 m. |
