2016年,长江中下游的洪水引起了全社会的广泛关注,围绕洪水成因、三峡工程在其中的作用等公众关心的问题,在这里给出一些答案。2016年长江发生了什么样的洪水?长江大洪水通常分为两类:区域性大洪水和流域性大洪水。2016年的洪水属于前者。洪水主要不是来自于三峡水库上游,而是由中下游地区的暴雨形成,所以2016年长江洪水为中下游区域性大洪水。 In 2016, the floods in the middle and lower reaches of the Yangtze River caught the attention of the whole society. Some answers were raised here on the issues of public concern such as the cause of the flood and the role of the Three Gorges Project. What kind of flood occurred in the Yangtze River in 2016? The floods in the Yangtze River are generally divided into two types: regional floods and watershed floods. The 2016 flood belongs to the former. Floods were mainly from the upper reaches of the Three Gorges Reservoir but from heavy rainfall in the middle and lower reaches of the Yangtze River. Therefore, the flood in the Yangtze River in 2016 was a regional flood in the middle and lower reaches.
