The paper is deal with the relation between rat species,density and loss of yield,The result shows that the species of rat are Apodemus agrarius,Cricetulus barabensis,Rattus norregicus and Mus musculus,and in which Apodemus agrarius is a dominant with 94.3%.The relation between density (x) and rate of loss (y) is significant different,The formula is y=0.936 6+0.946 1x.The ELT of the rat is determined with 2.3% of rat catching Rate.
