Abstract：Based on the study of sedimentary environment and chronology for Holocene sediments from Jiangling profile, Jiang-han plain, this paper studies these events on palaeo-flood which took place in Jianghan plain since Holocene, using some marks of magnetic fabric parameters of flood sediment The main results are as follows: (1) There are 55 large events of flood sediment since Holocene in Jianghan plain (excluding record data in history). (2) According to evolution, these events are divided into the stage of low frequency (9 875-3 000 a BP), which is more stable and has an approximate period of mainly one thousand year and 500-625 a, and the stage of high frequency (3 000 aBP～now), which is more frequent than the former, showing an increasing tendency and has a period of frequent occurrence of mainly 300-200 a.
