摘要:

对冰雪灾害后粤北地区的森林大型土壤动物功能群和生态特性进行初步调查,将研究区的大型土壤动物划分为腐食性、植食性和捕食性动物3个功能类群,其中腐食性动物的生物量占比例最大,而植食性动物的数量占优势,捕食性动物两者所占比例较小。土壤动物生物量最大的类群以寡毛纲蚯蚓为主,各样地土壤动物在土层中的垂直分布表现出明显表聚性特点,3个样地大型土壤动物群落DG指数由高到低依次为: 中亚热带针阔混交林>中亚热带常绿阔叶林>常绿与落叶阔叶混交林; 多样性指数(H)排序为中亚热带常绿阔叶林>常绿与落叶阔叶混交林>中亚热带针阔混交林; 均匀度指数(E)为常绿与落叶混交林>中亚热带常绿阔叶林>中亚热带针阔混交林; Simpson优势度指数(C)由高到低依次为常绿与落叶混交林>中亚热带针阔混交林>中亚热带常绿阔叶林。不同采样深度对大型土壤动物生态指数和功能类群的影响均为显著(P<0.01)。凋落物现存量与大型土壤动物群落生物量显著相关(P<0.05)。

Abstract:

An investigation of soil animal guilds and their ecological characteristics in North Guangdong was conducted after ice-snow damage in 2008.The results showed that soil animals were divided into three guilds based on their feeding function, i.e. saprozoite, phytophage and predacity, of which the saprozoite was predominant guild in biomass compared with other two guilds. The phytophage had more numbers of individuals than the others. Olgiochaeta were the dominant group. The soil fauna showed a distinct characteristic of surface accumulation in their vertical distribution. The variety of index(DG) from high to low was as follows: conifer-broad-leaf mixed forest in middle sub-tropical,evergreen broad-leaf forest and evergreen-deciduous mixed forest. The Shannon-Wiener index(H) from high to low was distributed as follows: evergreen broad-leaf forest,evergreen-deciduous mixed forest and conifer-broad-leaf mixed forest. And the Pielou evenness index(E) was evergreen-deciduous mixed forest,evergreen broad-leaf forest and conifer-broad-leaf mixed forest. However the Simpson dominance index(C) was evergreen-deciduous mixed forest,conifer-broad-leaf mixed forest and evergreen broad-leaf forest. The soil depth significantly influence the big soil animal ecological index and functional guilds (P<0.01). Litter amount in stock was significantly corrected with biomass of soil animal community(P<0.05).
