窦店村家鼠密度在不同环境间差别非常显著，楼房区为９．８４％，平房区为１７．０５％，特殊行业为６０．５３％。褐家鼠在３种环境的分布极不平衡，楼房区为０，平房区为２．４６％，特殊行业为５２．６３％：小家鼠在３种环境的分布较平均。相对而言，居民区的主要害鼠是小家鼠，特殊行业主要是褐家鼠。调查结果还显示，居民区不同类别房间的鼠密度因食源丰富度、防鼠性等不同而差别非常显著。养猫虽对家鼠有一定影响，但远远不能消除鼠害。卫生的好坏对家鼠密度的影响较大，其中对褐家鼠的影响更显著。农村住房由平房向楼房的发展及卫生条件的改善，会导致家鼠密度下降及家鼠种类组成中大型鼠构成比下降，而特殊行业的鼠害及大型鼠的构成比则上升。
Doudian village house rat density in different environments, the difference is very significant, building area 9.84%, cottage area 17.05%, special industry 60.53%. Rattus norvegicus distribution in the three kinds of environment is extremely unbalanced, building area is 0, cottage area is 2.46%, special industry is 52.63%: Mus musculus in three kinds of environment distribution more evenly. Relatively speaking, the main pests in residential areas are Mus musculus, and the special trades are mainly Rattus norvegicus. The survey results also show that the density of rats in different categories of residential areas is very different due to the richness of food, rodent resistance and other differences. Although domestic cats have a certain impact on house mouse, but far from elimination of rodent pests. The health of the rat density greater impact, which has a more significant impact on Rattus norvegicus. The development of rural housing from bungalows to buildings and the improvement of sanitation conditions will lead to a decrease in the density of domesticated rats and a decrease in the composition ratio of large rats in domestic animal species, while the proportion of rodents and large rats in special industries will increase.
