摘要: 为研究洪灾发生的规律,减少洪灾损失,根据历史记录,分析了长江与黄河洪水和干旱出现的原因,根据长江流域近1 000年来的气候干湿变化规律,探讨洪水和干旱周期;对1840年以来长江与黄河洪灾等级和频率进行对比;对洪水和洪灾发生的特点及减灾措施进行综合分析。研究表明,两流域同时发生大洪水的机率较小,而同时干旱的机率较大;长江流域洪水频率大于干旱频率,且中下游发生洪灾的机率大于上游;长江流域水灾频率比黄河大。

Abstract: In order to study flood-damage rules,it is necessary to recognize the history of flood. According to the historical records, the occurrence rules of dry and flood for both Yangtze River and Yellow River were analyzed. Based on the dry and humid changes of climates in recent 1000 years in the Yangtze Basin, the periodic dry-flood variations were discussed and the flood frequencies and disasters from 1840 to present were analyzed, flood characteristics and relieving measure were proposed. The study shows that the probability of simultaneow occurence of flood in the two basins are low but the probability of dry are high; the flood frequency is higher than dry frequency in Yangtze River basin; the flood frequency in Yangtze River is higher than in Yellow River; flood frequency in middle and lower reaches of Yangtze River is higher than that in its upper reach.
