Abstract: The controlled irrigation area of an irigation area in the south of Wusu city in Xinjiang is 5200hm2 .Due tothe aging of the canal system,the leakage is serious,and the water resource utilization eficiency is only 54.5% which leads to regional salinizationand engineering water shortage.The study area is adjacent to the qingshuihezi fault (F1,historical7.7magnitudeearthquake)andTuoSitai fault zone (F11,latePleistoceneactivefault)withinthe strong earthquake tectonic zoneof the North Tianshan Mountains，with significant risk of tectonic activity. Through field investigation,earthquake monitoring and data analysis,the assessment shows that the peak ground motion acceleration in the project area is 0.15-0.20g (VI- VII intensity),and the spatial coupling between active faults and alluvial plain landform exacerbates engineering hazards.Key implementation measures are put forward: Taking avoidance measures and seismic design for high-intensity earthquake areas,arranging monitoring networks at fault zones,and establishing a comprehensive earthquake emergency response mechanism. The study results provide the support forthe linkage analysis methodof "fault activity channel system earthquake resistance"forirrigation projects in strong earthquake areas,and have demonstration significance for disaster prevention of similar water conservancy projects in Xinjiang.
