摘要
土壤动物的生存、活动与栖息地环境密切相关。一方面栖息地生态因子决定着土壤动物的生存与活动;另一方面,土壤动物对土壤有机质的改变、土壤微生物的生存、植物的生长等诸生态因子的变化起着一定的促进作用。因此随着草原生态系统研究的日趋深入。
Investi gations on soil fauna are made in the natural reserve of Xilinguole grassland.Indifferent habitats of the grassland ecosystem,the species and quantity of soil fauna arenot only varied with the type and properties of soil,but also influenced comprehensivelyby other ecological factors.Therefore,the species and quantitative distribution of soll faunacan reflect the characteristics of different habitats to a certain extent.They are suggestedto be taken as the indicator for the fertility level of different soil types in the grasslandecosystem.
