安徽省防御“利奇马”台风工作启示

Enlightenments of Typhoon Lekima No.201909 in Anhui Province

2019年8月10日,201909号台风“利奇马”重创皖南山区天目山脉西侧,安徽宁国市水阳江上游中津河、东津河发生超历史记录洪水,水文部门及时预警,政府有序组织人员转移,避免宁国市城区重大人员伤亡。东津河上游因特大暴雨引发山体滑坡、泥石流灾害,发生人员伤亡。经过调查考证,暴雨区短历时降雨量超过实测历史极值,重现期超过50a、甚至局部超过100a,也是灾害发生的主要原因,中津河、东津河上游人类活动影响导致次生灾害加剧,宁国市城区东津河治理依然存在明显短板。

Located in the south of Anhui Province,the western region of the Tianmu mountain was significantly affected by the Typhoon Lekima No.201909 occurring on August 10,2019. The Zhongjin River and the Dongjin River in the upper reaches of the Shuiyang River in Ningguo City,Anhui Province have recorded historical floods. The hydrological department promptly warned,and the government organized the orderly evacuation of personnel to avoid major casualties in the urban area of Ningguo City. The upper reaches of the Zhongjin River and the Dongjin River,experienced landslides and mudslides,causing casualties. Through investigation and research,the short duration rainfall in the rainstorm area exceeds the measured historical extreme value,and the return period exceeded 50 years,or even more than 100 years in certain locations,which is also the main cause of the disaster. The impact of human activities in the upper reaches of Zhongjin River and Dongjin River leads to the aggravation of secondary disasters,and the governance of Dongjin River in the urban area of Ningguo City still has obvious shortcomings.
