| 摘 要： | 研究了天台山8种植被类型土壤微生物DNA总量分布的特性及其与土壤微生物数量、土壤生化活性和土壤其它环境因素之间的关系。土壤的发育程度等对土壤微生物DNA总量分布影响较大。此外,土壤微生物数量、微生物生物量C和土壤呼吸速率对土壤微生物DNA总量分布的直接作用和它门之间的相互作用产生的间接影响较显著。在所测的8种土壤理化因素中,土壤微生物DNA总量分布对土壤pH、有机质、全氮、全磷、全钾影响较大。

| Abstract: | The distribution properties of total soil microbial DNA resources and the relationships between the total microbial total DNA distribution and the microbial number,biochemical activityies and other environmental factors in different vegetation soils of Tiantai mountain were studied.The developing degree of soil and the fertilizing managements take great effect upon the distribution of the total microbial total DNA resources in soils.In addition,the soil microbial number,microbial biomass C and soil respiration rate play obviously direct role in the distribution of the total DNA resources,the interactions of which also play obviously indirect role.The distribution of the total microbial total DNA play important role in soil pH,organic matter,total nitrogen,total phosphorus,total postassium content. |
