东北森林土壤动物同功能种团及其生态分布

对位于小兴安岭的东北林业大学凉水自然保护区和位于张广才岭的东北林业大学帽儿山实验林场的土壤动物进行了研究。结果表明，该地区土壤动物可划分为腐食性、植食性，捕食性动物三个同功能种团，土壤动物各同功能种团在组成、个体数量、生物量等方面均具有相对稳定性，群落土壤动物同功能种团的数量分布状况能在很大程度上反映群落环境的相似与差异程度；群落中各土壤动物同功能种团的个体数量间无明显的相关性，但腐食性动物与捕食性动物两个同功能种团的生物量之间具有的相关性。图1表2参13

Soil animal guilds and their ecological distribution in the northeast of China

In researches of the soil animal of Liangshui and Mount Maoer, we divided the soil animal into three guilds concluding saprozoic, phytophage, predacity animals. The results show that each guild of soil animal possesses relative stability in composition, number of individuals, biomass and so on. The distribution pattern of quantity of soil animal guilds in communities is able to widely reflect the environmental similarity and difference degree among communities. There is not obvious relativity in number of individuals between three guilds, but there is obvious relativity in biomass between saprozoic and predacity animal. Fig 1, Tab 2, Ref 13
