STUDY OF THE RODENT' S CHOICE OF VEGETATION AND HARM DONE TO IT

啮齿动物是与人类关系最为密切的一个动物类群。作为有害动物,人类利用一切手段消灭它们;作为动物界的物种,它又不能被完全消灭。调查研究贺兰山东麓半荒漠地区人工植被代替自照植被后对啮齿类的影响,在科学研究和生产实践中都有一定的意义。

The rodent is a kind of animal group which has the most closed relationship with mankind. As they are harmful animals, man takes every way to wipe them out. But as they are also one species of the animal kingdom, they cannot be completely wiped out.Therefore, to invistigate and study the effects of the vegetation on the rodents, when the artificial vegatation replaced the natural one in the desert and semi-desert area of East Helan Mountain, has a great significance in the sci entific research and production activity.
