研究祁连山南麓冻土区热融地质灾害分布规律及主控因素。利用2019～2021年青海省冻土热融地质灾害调查成果，对已调查的热融滑塌、融冻泥流和热融沉陷三种地质灾害数据，分析其空间分布特征，采用信息量模型和地理探测器对三类灾害进行分析驱动力分析。祁连山南麓共发育热融灾害点165处，主要分布在祁连县、天峻县，灾害规模主要以中小型为主。各灾害在海拔3 600 m以上且坡度小于12°及12°～25°的阳坡较为发育。单因子对热融地质灾害的影响程度中，降雨因子的影响力最强，坡向因子的影响力最弱。不同因子之间交互作用的解释力均呈增强效应，其中，双因子增强关系为60.7%,非线性增强关系为39.3%,无相互独立作用的因子。

Based on the result of thermal thawing geological hazards in frozen soil in Qinghai Province from 2019 to 2021, spatial distribution characteristics of the surveyed data on thermal thawing collapse, thawing mud flow, and thermal thawing settlement were analyzed. Information quantity models and geographic detectors were used to analyze the driving forces of the three types of disasters. The result show that: there are a total of 165 heat and melt disaster points developed at the southern foot of the Qilian Mountains, mainly distributed in Qilian County and Tianjun County, with small and medium-sized scales being the main ones. Mainly distributed in the Tole Mountain and Tole South Mountain, and the Datong River source area is also relatively developed; The southern foothills of the Qilian Mountains are more prone to thermal melting geological hazards on sunny slopes than on shady slopes. It mainly develops on gentle slopes in the east, south, and west directions, with low-lying slopes less than 12 ° and 12 °～25 °. The distribution of various disasters in elevation has similar characteristics, mainly distributed in areas above 3600 meters above sea level. Among the effects of single factors on thermal melting geological disasters, the influence of rainfall factor is the strongest, and the influence of slope factor is the weakest. The explanatory power of the interaction between different factors shows an enhancement effect, with a dual factor enhancement relationship of 60.7% and a non-linear enhancement relationship of 39.3%. There are no independent factors that act on each other.
