2004年6月—2006年4月,选择浙、闽、赣交界山地的4个森林片段作为研究地点,并以浙西的古田山国家级自然保护区作为连续森林对照,采用尼龙网袋法,研究了不同常绿阔叶林群落优势种木荷凋落叶的分解速率及土壤节肢动物群落的结构和动态.结果表明:5个研究地共获土壤节肢动物1050个,分属8纲23目,其中鳞翅目、膜翅目、弹尾目和双翅目占个体总数的10%以上,为该地区的优势类群.片段化对群落物种组成的影响主要体现在稀有类群的差异上.不同分解阶段各种土壤节肢动物类群优势度因其功能的不同而各异.经过2年的分解,各研究地木荷凋落叶损失量为60%～70%,研究地凋落物中土壤节肢动物的各项多样性指标均有一定的变化,且与连续森林的变化规律不一致.
From June 2004 to April 2006, 4 forest fragments of Zhejiang, Fujian and Jiangxi were chosen as the study sites. Taking Gutian Mountain National Nature Reserve in western Zhejiang as the continuous forest control, The decomposition rates of dominant species of litter and the structure and dynamics of soil arthropod communities in different evergreen broad-leaved forest communities were studied.The results showed that 1050 soil arthropods were found in 5 study sites, belonging to 8 orders and 23 orders, Among them, Lepidoptera, Hymenoptera, Phalacrocorax and Diptera accounted for more than 10% of the total number of individuals, which was the dominant group in this area.The impact of fragmentation on species composition of community was mainly reflected in the differences of rare groups.Different decomposition stages The dominance degree of various soil arthropod groups varies with their functions.After 2 years of decomposition, the losses of the wood-lotus leaf litter in each study range from 60% to 70%. The soil arthropods in litter Diversity indicators have some changes, and inconsistent with the law of continuous forest changes.
