祁连山区分布有啮齿动物2目8科36种。在海拔2300~2800m的中山地带,中华鼢鼠是当前区内最严重的鼠害,中华鼢鼠又称瞎狯、瞎鼠、半地龙等。广泛分布于祁连山区不同海拔、不同坡向的林地内,严重危害云杉、落叶松、杨树、沙棘等树种的人工幼林及天然灌木林。一般鼠口密度每公顷15~22.5只,幼树被害株率达10%~40%,平均达18%。近年来,由于环境恶化,中华鼢鼠的天敌猫头鹰、黄鼠狼等日益减少,若不及时防治,3—5年即可将幼林全部毁灭,林业专业技术人员对此苦不堪言。

In the 2300 ~ 2800m above sea level in the Zhongshan area, the Chinese zokor is the most serious rodent in the area, Chinese zokor, also known as blind zap, blind mouse, half to the dragon. Widely distributed in the Qilian Mountains at different altitudes and different slopes of the woodland, serious damage to spruce, larch, poplar, seabuckthorn and other tree species of artificial young and natural shrubs. General rat population density 15 ~ 22.5 hectares per hectare, saplings killed plants rate of 10% to 40%, an average of 18%. In recent years, due to the deteriorating environment, the natural enemies owl and weasel of Chinese zokor rats have been declining. If you do not control them in time, you will be able to destroy all the young forests in 3-5 years and your forestry professional and technical personnel will be mired in this.
