| 摘 要： | 对大兴安岭北部不同恢复年份火烧迹地大型土壤动物进行了研究.结果表明,不同恢复年份火烧迹地大型土壤动物可以划分为腐食性、植食性和捕食性3个生态功能类群.不论是个体数量还是生物量,均以腐食性动物所占比例最大,植食性和捕食性动物所占比例很小.除恢复1a的迹地中捕食性动物数量比例较大,其它样地均表现出腐食性动物所占比例较大,且...

| Abstract: | A survey was conducted to study the change of soil macro-animals in the burned forest areas in northern Daxing’an Mountains of China at different restoration stages.The soil macro-animals could be divided into three guilds: saprophagy,phytophage and predacity.The aprophagous animal was predominant guild compared with the other two guilds in both individual number and biomass.Except for the sample plots one year after burning which had the highest percentage of predatory animals,the proportion of saprophagous animals was the largest in other sample plots.And the proportion increased when the environmental conditions were better.A significant positive correlation was only observed between the number of saprophagous animals and the number of predatory animals,while significant positive correlations were found between biomass of all the guilds. |
