摘要
运用ＳＡＳ软件的非线性回归，并结合马尔可夫链方法建立了因洪涝灾害造成的我国农田受灾及成灾面积的２个预测模型，结果表明本文所作的预测效果较好，为我国的灾害预测提供了一种方便实用的方法．
By NLIN procedure of SAS software and the method of Markov chain, we propose two predictive models for disaster area and destroyed area caused by flood and waterlogging in our country. It is shown that the prediction is fairly good. Which affords a useful method for the disaster prediction in our country.
