摘要： 天童常绿阔叶林演替过程中，凋落物质量的变化是影响土壤动物群落的主要因子.凋落物层土壤动物群落总密度与凋落物C/N之间存在显著负相关（r=-0.681, P<0.001），与总磷含量存在显著正相关(r=0.762, P<0.001), 但类群总数与各养分含量之间均无明显相关性；0~15cm土层中土壤动物群落总密度与土壤有机质（r=0.457, P<0.05）、总氮（r=0.463, P<0.05）和总磷（r=0.564, P<0.01）间均存在显著正相关，类群总数与总氮（r=0.528, P<0.01）和总磷(r=0.632, P<0.001)显著正相关.主要土壤动物类群密度与各养分含量之间的相关性不同：凋落物中螨和跳虫与凋落物总氮、总磷含量呈极显著正相关， 而土层中的跳虫却与土壤各养分含量间表现出不明显的负相关，螨与土壤总氮、总磷含量呈显著正相关；膜翅类与凋落物和土壤总磷含量均呈显著正相关；凋落物层综合类、土层线虫、线蚓和鞘翅类分别与凋落物和土壤各养分含量间呈显著正相关.

Abstract: The change in litter quality is the main factor influencing the soil animal community in the succession of the Evergreen BroadLeaved Forest in Tiantong. The total density of soil animal community in the litter layer is in a remarkably negative correlation with C/N value of litter (r=-0.681, P<0.001), but in a markedly positive correlation with total phosphorus （TP）content(r=0.762, P<0.001). However, the total number of soil animal group in litter has no marked correlation with all nuritent contents. In the soil in depth of 0~15cm, the total density of soil animal community is remarkably positively correlated with organic matter content（r=0.457, P<0.05）, total nitrogen (TN) content（r=0.463,P<0.05）and total phosphorus (TP) content（r=0.564, P<0.01）. And the total group number is noticeably positively correlated with TP and TN. Furthermore, there are different correlations between density of main soil animal groups and nutrient contents. In the litter, the density of Acarina and Collembola are extremly markedly positively correlated with TN content and TP content of litter. In the soil, that of Acarina does. However, that of Collembola appears negetive correlation with all soil nutrient contents. Hymenoptera in the litter and soil are markedly positively correlated with TP content. The density of Symphyla in the litter and that of Nematoda, Enchytraeidae and Coleoptera in soil have respectively profoundly positive correlations with all litter nutrient contents and soil nutrient contents.
