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。
According to more than 4,000 specimen identification and literature records, there are 21 species, 2 orders, 4 families and 2 rodents in the Loess Plateau of Shaanxi Province, of which 13 species belonged to the Paleo-Benthic community, accounting for 61.4% of the rodents in this area, belonging to There are four species of the Oriental community, accounting for 19.3% of the rat species in the area, there are four kinds of widespread species in the world, accounting for 19.3%. The rodent fauna of the Loess Plateau in northern Shaanxi is mainly dominated by the fauna of the Northern Palaearctic communities, especially the North China-Loess Plateau, including a few Oriental Ocean fauna and broad-distributed species with distinct paleo- Characteristic rodent herd. The most harmful species in agriculture, forestry, animal husbandry and soil and water conservation in the Loess Plateau are zokor, Daurian wallaby, Daurian ground squirrel, big hamster and so on. Take chemical control strategies, agro-ecological farming practices and grassland ecological measures and other ecological control strategies to keep the damage caused by rodent pests within the allowable economic losses.
