新疆南部山区泥石流灾害发育程度高,灾害暴发频发,以南疆阿图什市为例,对成灾特性进行重点分析,阐明稀性泥石流灾害赋存的地质环境条件与基本特征,对致灾三大要素——地形地貌特征、泥石流物源与水源条件进行分析研究,结果表明,该市泥石流类型主要为由暴雨诱发的破面侵蚀沟谷型稀性泥石流,爆发频率及规模为中型。厘清成灾特性,为后续的防治工程设计奠定研究基础。 The mountainous areas in southern Xinjiang have a high degree of development of debris flow hazards and frequent outburst of disasters. Taking the Atushi City in southern Xinjiang as an example, the disastrous characteristics are mainly analyzed to clarify the geological and environmental conditions and basic characteristics of the rare earth debris flow disasters, The results show that the main types of debris flow in the city are the thin-section debris flow caused by rainstorm, and the frequency and scale of outbreak are medium. Clarify the disaster characteristics, and lay the foundation for the subsequent prevention and treatment engineering design.
