阿坝州面临严峻的地质灾害形势。全州现有3468处地质灾害隐患点，20余万名群众处于威胁之中，占该州总人口的四分之一1。2026年9月16日，茂县叠溪镇石大关村发生了80万立方米的大规模滑坡1，但因提前一个月组织受威胁群众转移，这次灾害未造成人员伤亡。事发前的8月20日至24日期间，茂县已组织161名受威胁群众完成避险转移1。
为应对持续的地质灾害威胁，当地政府探索了避险转移补助机制。松潘县从2022年起实行避险转移补助政策，初期按每人每天30元的标准发放补助1；到2024年起改为直接在安置点向群众发放现金1。同样的防灾预警能力也在实战中得到验证。2026年7月16日晚9时30分左右，梭罗沟村发生泥石流，村支书杨小青及时组织下游村民和游客撤离1。
气象部门的预报显示，防灾工作的紧迫性可能进一步上升。国家气候中心预计2027年夏季中国气候受厄尔尼诺影响将比2026年更为显著，中东部降水总体偏多1。
Aba Prefecture in Sichuan Province faces an acute geological disaster crisis, with 3,468 hazard points threatening more than 200,000 residents—equivalent to one-quarter of the region's total population 1. The state has developed an approach centered on early warning systems and organized evacuations to mitigate risks from landslides and debris flows that regularly endanger communities in this tectonically active area 1.
A major incident occurred on September 16, 2026, when Shidaguan Village in Diexi Town, Maoxian County, experienced a large-scale landslide measuring 800,000 cubic meters 1. Crucially, no casualties resulted from this event because authorities had already relocated 161 threatened residents between August 20 and 24—one month prior to the disaster 1. Similarly, on July 16, 2026, around 9:30 p.m., a debris flow struck Suoluo Gully Village, where party secretary Yang Xiaoqing promptly organized the evacuation of downstream villagers and tourists 1.
To support residents living in hazard zones, Songpan County launched an evacuation assistance program in 2022, providing 30 yuan per person per day to those displaced 1. The system evolved in 2024 to direct cash distribution at designated resettlement points, streamlining aid delivery 1. The National Climate Center projects that summer 2027 climate conditions will be influenced more significantly by El Niño effects than 2026, with increased precipitation expected across central and eastern regions 1.
