In Songpinggou watershed,characterized by its well-developed faults and frequent geological disasters,stud-ies were conducted to investigate the impacts of the Songpinggou fault on these hazards.Field surveys and geophysical exploration methods were utilized to delineate the development of the fault along the main valley of Songpinggou,and detailed investigations of the geological hazards in the area were carried out.As a result,a better understanding of the fault's influence on geological disasters was achieved,which provide a reference for the prevention and control of such hazards in the region.The research results are as follows.The overall trend of the rupture zone of the Songpinggou fault extends northwestward along the main valley of Songpinggou,starting from the arcuate structure zone in Mao County and its western side,and is divided into three segments arranged in a staggered manner.Geological disasters are dis-tributed in a belt-like pattern along both sides of the fault,with a higher frequency and larger scale of disasters occur-ring closer to the fault,and a concentration of geological hazards at the endpoints of the fault.The development of geo-logical disasters is seen to be oblique to the trend of the fault,indicating a long-term influence from the fault's activity;the scale of geological disaster development gradually decreases from the southeast end to the northwest end of the fault,further suggesting a gradual weakening of the fault's activity.
