| 摘 要： | １９９１年６～９月在内蒙古大安岭吉文林区共设置２７块野外样地，对该地区的啮齿类区系进行了调查，１９９２年１０月到１９９３年５月选择野外样地４块对鼠类危害进行了调查，结果发现当地啮齿动物共有２目６科１２种，鼠类的密度与林龄有密切关系，林龄较长的林地鼠类密度较低。当地干旱阳坡樟子松１５ａ以下林木受害鼠危害最为严重，其被害率高达３０％，幼林地和新植林地受害鼠危害也较严重，被害率达２０％。

| Abstract: | The 27 plots were selected and rodent fauna was investigated on the Jiwer forest region in Daxingan Mountains from June to September in 1991. From Oct, in 1992 to May, in 1993 the rodent harm was investigated on the 4 plots selected, the results showed there were 2 order, 6 family, 12 speecies. The rodent density was related to tree age. There were lower rodent density on the forest land of with longer tree age, Below 15 years of Pinus sylvestris var. mongolica below 15 years was mostly harmed on the dry south of hill in the region and harmed tree rate was 30%, the rodent harm was more serious in the yong forest and new planting tree and the harmed tree rate was 20%. |
