今年汛期，我国很多地区遭受了严重的洪涝灾害。长江、松花江、嫩江、闽江以及珠江流域的西江等江河都出现了罕见的大洪水。造成今年洪涝灾害的主要原因是气候异常，同时，江河中下游防洪标准偏低，上中游生态环境遭到破坏，水库工程控制洪水能力较低等，也是很重要的原因。为 In this year’s flood season, many areas in China have suffered severe floods. The Yangtze River, the Songhua River, the Nen River, the Lancang River, and the Xijiang River in the Pearl River Basin have seen rare floods. The main cause of this year’s flood disaster is climate anomalies. At the same time, the flood control standards in the middle and lower reaches of the rivers are relatively low. The ecological environment in the upper and middle reaches has been destroyed, and the ability of reservoir projects to control floods is also an important reason. for
