In this paper, the spatial-temporal features of waterlogging for rape in Anhui Province was analyzed from 1961 to 2010 based on the industrial standard(QX/T 107-2009). The result showed that the waterlogging index gets the maximum value in blossom-bolting stage, when about 70%~80% waterlogging occurred. The index had a rising trend in bolting stage while decreased in filling stage; In the space, the value of waterlogging indexes increased regularity from north to south. The waterlogging occurred mainly in the south of Huai River Valley. The appearance of rape waterlogging is on a 5~6 years cycle in Jianghuai region.In Yanjiang region, the appearance of waterlogging is on a 2 years cycle,among them, mild waterlogging on a 3~4 years cycle, moderate waterlogging on a 5~6 years cycle, severe waterlogging on a 15~16 years cycle. In Anhui South region the appearance of waterlogging is on a 1~2years cycle, among them, mild and moderate waterlogging on a 3 years cycle, severe waterlogging on a 5 years cycle.
