摘要
"5·12"汶川特大地震造成的灾区地表松动,使处于雨季的灾区面临山洪灾害的严峻挑战。通过对比历史上灾区和近邻地区已发生山洪灾害的历史状况,分析灾区山洪灾害的重点防范月份,绘制灾区山洪灾害高、次高、中、低易发区的分布位置,提出了不同风险区防范山洪灾害的应对措施,供汶川特大地震灾后山洪灾害预警参考。
The loose of current land surface after Wenchuan Ms 8.0-magnitude earthquake on May 12th, 2008 may cause the high risk of mountain torrents disaster in rainy season. Based on historical events and information of vicinity, this paper presents the possible months incurring the mountain torrents disaster and four possible zones where the mountain torrents hazard is high, less high, middle, and low. Four countermeasures are put forward respectively to each of the hazard zones to keep away from mountain torrents disasters.
