摘 要:通过研究发现不同林分类型中,节肢动物在个体数量上,山杨桦木混交林和樟子松林明显高于华北落叶松林;在组成结构上,三种林分类型中不仅具有共有类群,还分别具有特有类群;发现节肢动物具有垂直分层现象,并具明显的表聚性,三种林分类型在不同土壤层次之间均表现出递减的变化,但樟子松林中的变化明显小于其他两种林分;在0~10 cm的土壤中,温度和湿度是影响土壤节肢动物的主要因素,其中华北落叶松林中土壤节肢动物的变化与温度和湿度均呈现极显著的正相关关系,其它两种林分中湿度的影响较大,在10~15 cm的土壤中,各林分的影响因素差异较大。Individuals of arthropods in Mixed forest of aspin and birch and Scotch pine forest were significant higher than that in North china larch forest; both common groups and special groups were found in arthropod of 3 forest types by the study of arthropod structure; the arthropod community was shown a situation of vertical lay- ered and significant surface accumulation, the arthropods were decreased as the deep of soil layer in 3 forest types and such a trend was gender in Scotch pine forest than that in other 2 forest types ; temperature and humid- ity were the most important factors in the soil 0 ~ 10cm underground, both temperature and humidity were shown significant relations to soil arthropod in North china larch forest while the humidity shown a more important im- paction, and the impact factor was very different in the soil 10 - 15cm underground of different forest stands.
