摘　　要：通过洞庭湖稻区水稻田的害鼠群落和害鼠对水稻损失量的调查，用多元回归方法建立了水稻损失量和害鼠密度的关系模型：Ｙ＝０．０６７４Ｘ１＋０．０３０７Ｘ２－０．１６２７，并计算当地水稻经济允许损失水平Ｌ＝０．１３１７％，据此可确定稻田害鼠复合防治指标，并算出单种害鼠的防治指标（夹夜捕获率）：东方田鼠为４．３７％，黑线姬鼠为９．５９％This paper reporls the study on the multiple control criteria of pest rodent in Dongting Lake rice areas. The result shows both the density of pest rodent( Apodemus agrarius and Microtus fortis) and loss of rice yield are positively relative. The regression equation is Y=0 0674X 1+0 0307X 2-0 1627(X 1—the density of Apodemus agrarius,X 2—the density of Microtus fortis). The economic permissible loss of rice yield is 0.1317%. The control should be begun when the density of A. agrarius was 9.59% and M. fortis was 4.37%.
