摘要
昭通“7.12”暴雨过程诱发了区域性滑坡泥石流的强烈活动,造成严重的灾害。本文通过对灾害现场考察,剖析了暴雨成因、时空分布,并阐明了“7.12”暴雨滑坡泥石流区域分布和成灾特征,并以彝良县为例,探讨了暴雨与滑坡泥石流形成关系。根据昭通地区暴雨滑坡泥石流发生规律和发展趋势,提出了减灾对策。
'7·12' torrent rsin in Zhaotong areas induced the regional landslide and debris flow activity, and cause serious hazards. According to on-the-spot investigation on disaster,authors discussed the distribution and hazardous characteristics of landslides and debris flows triggered by '7·12' torrent rain, and analysed the rainfall reason and distribution. Citing Yiliang an example in point, authors approached the relationship between torrent rain and formation of landslides and debris flows. Based on the occurrence laws and developing trend of rainstorm-induced landslides and debris flow of Zhaotong region. In the last of this paper, The countermeasures against landslide and debris flow disaster was put forward.
