Abstract

利用BIOLOG 微孔板法研究了秦岭山脉的锐齿栎( Quercus aliena var. acutidentata) 、油松( Pinus tabuliformis) 、华山松( Pinus
armandii) 、松栎混交、云杉( Picea asperata) 6 个林地5 种典型林分土壤微生物群落代谢特征。发现: ( 1) 5 种典型林分中,华山松
的平均颜色变化率( AWCD) 最高,然后是锐齿栎1>云杉>油松>锐齿栎2>松栎混交。位于不同林场的锐齿栎林地土壤AWCD
值差异较大; ( 2) 土壤微生物功能多样性指数与平均颜色变化率表现一致,6
种林分之间差异显著,且不同的林分土壤微生物对
6 种碳源利用差异较大。( 3) 主成分分析显示各土壤微生物功能多样性具有显著差异,其综合因子得分为华山松>锐齿栎1>油
松>云杉>锐齿栎2>松栎混交。( 4) 冗余分析表明土壤pH、有机质、全氮、碱解氮、速效磷和速效钾的综合作用对土壤微生物群
落功能多样性有显著影响,其中速效磷和pH 与土壤微生物功能多样性最密切。

Other Abstract

In this study, the BIOLOG microporosity plate technology was employed to investigate the metabolic
characteristics of microbial community in six woodlands with five typical types of forest soils,which included forest soils
planted with tooth Oak ( Quercus aliena var. acutidentata ) ,chinese pine ( Pinus tabuliformis ) ,armand pine ( Pinus
armandii) ,pine and oak mixed,spruce ( Picea asperata) . The major findings include: ( 1) The average well color
development ( AWCD) of armand pine is the highest among the five kinds of typical forests,followed by tooth Oak1> spruce
> chinese pine > tooth Oak2>pine and oak mixed,The AWCD value of tooth Oak woodlands located in different forest farms
showed large differences among each other; ( 2) The index of soil microbial function diversity is consistent with the AWCD.
The differences among six forest lands showed significant difference,.
Significant difference was also observed for the
utilization of six carbon source by soil microorganism in different forest components. ( 3) The principal component analysis
showed that the soil microbial functional diversity among different soils were significant different. The sequence of
comprehensive factor scores were armand pine > tooth Oak1> Chinese pine > chinese spruce > tooth Oak2> pine and oak
mixed. ( 4) Redundancy analysis shows that the comprehensive effect of soil pH,organic matter,total nitrogen,alkali
hydrolyzable nitrogen,the available phosphorus and available potassium can significantly affect soil microbial communityfunctional diversity,especially the available P and pH which were closely related to soil microbial functional diversity.
