摘要
Based on the historical data of the excessivc rains ovcr the middle-lower reaches of Changjiang River in two hundred and fifty years (1651--1900) and the data of 'Very Large' volcanic eruptions (VEI≥5) in the period of 1650--1900, which are selected from the table of volcanic eruption year complied by Sim- kin et al. (198l). This paper analyses the interannual variation of various kinds of continuous rains in the historical period, as well as the relation between plum-continuous rains and waterlogging along Chang- jiang-Huaihe reaches, and between 'Very Large' volcanic cruption and continuous rains over the middle- lower reaches of Changjiang Rivex.
