【摘要】 <正> 群落生境及棲息地的研究为近来动物生态学上很重要的一个方向,很多农林措施及疾病疫源的探寻都脱离不了这方面的研宪。森林采伐以后,植被变化产生了新的群落生境,因而动物的区系及数量的关系也就变化了。(1952)曾指出森林采伐后脊椎动物区系变化的趋势,而Tevis(1956)更着重地研究了采伐迹地更多还原

【Abstract】 Basing on a study of 17 samples, each of which is at least 2 hactares in area, the authors have divdded the old cut-over lands of North-eastern China into 5 types, namely, 1) sparse forest, 2) oak (Quercus mongolica) forest, 3) hazel-nut (Corylus heterophylla) bush-woods, 4} barren fields and 5) meadow. In the sparse forest, the rodent fauna is quite the same as that of the virgin forest, the dominant species being wood mouse (Apode-mus spetiosus), red-backed voles (Clethrionomys rutilus and C. rufocanus), with the striped field mouse (Apodemits agrarius) beginning to invade such areas. In the oak forest type of the cut-over land, the voles diminish in number. In hazel-nut bush-woods and barren fields, voles have basically dis-apeared, but the striped field mice are increasing in number. In the barren fields, they occupy 70.4% of the rodents’ total population. In the meadow, in addition to the above 4 species, there is a considerable number of reed voles (Microtus maximowiczii), which may be considered as its characteristic species. The role of the rodents in forest regeneration has also been estimated.更多还原
