Abstract：The historical datum and nowadays' records have manifested clearly that the frequency and situation of drought corresponded basically to the catastrophic flood in the middle reaches of Yangtze River,where is the area that the flood took place frequently,also the area that the drought took place frequently. The drought and the catastrophic flood turned up by turns with the cycle of 2 a,and often turned up in the same year.The drought not only distributed widely but also lasted long,and it's loss can't be neglected.The drought and the catastrophic flood in the middle reaches of Yangtze River had the obvious increasing tendency.There are many reasons responsible for this but the main are: ecological environment being bad,the space of store floodwater being reduced and making much of preventing the flood but making little preventing the drought in the water conservancy for long-standing and so on.There are four suggestions: the one is to change the tradition concept of making much of preventing the flood but making little preventing the drought,to turn "preventing the flood and fighting a drought" into "preventing the flood and preventing the drought";the two is to establish the net system of rivers,sluice-ways,lakes and pools referring to the net system of the early 1960's;the three is to expand the ability of lakes saving water;the four is to establish draining and saving water system with the deep ditch and sluice-way of farmlands.
