On the basis of glires investigation during 1986,1987,1988 and 1993,more than 4 000 speciemens of the glires collected from loess plateau of northern Shaanxi province were identified and the fauna have been analysed.The results show that there are 21 species of glires which belong to 4 families and 2 orders,13 species of them belong to palaearctric realm and is 61.4% of total species,4 species were species of orientat,and 4 species belong to widely spread species which are 19.3% of total species separately.For population control of the glires and keep low population density longer,comprehensive measures of ecological tillage on the farmland,ecological management on the meadow,chemical poison baits control and capture instruments have been adopted.The effects of chemical control is put forward in this paper.
