摘要
通过４０００余号标本鉴定及文献记载，陕北黄土高原的啮齿动物有２目４科２１种，其中属于古北界的种类有１３种，占该区啮齿动物种数的６１．４％，属于东洋界的种类有４种，占该区鼠种的１９．３％，世界广布种有４种，占１９．３％。陕北黄土高原的啮齿动物区系主要是以北方古北界种类，特别是华北——黄土高原的区系成分为主体，包括少数东洋界区系成分和广布种，具有明显古北界区系特色的啮齿动物类群。对黄土高原的农业、林业、畜牧业和水土保持事业危害最大的种类，主要有鼢鼠、达乌尔鼠兔、达乌尔黄鼠、大仓鼠等。采取化学药剂防治、农业生态耕作措施、草地生态措施等生态运作调控策略，把鼠害造成的损失长期保持在经济允许的损失范围之内。
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.
