| 摘 要： | 选取中国科学院红壤生态实验站的8种植被,用BIOLOG法检测了土壤细菌群落的碳源利用,并分析了16种土壤性质,利用主成分分析与回归分析方法研究了土壤性质对细菌群落碳源利用的影响.结果表明,7项土壤性质解释了细菌碳源利用总变异的54.9%,其中,土壤溶解性有机质碳氮比解释了14.3%,砂粘比、微生物碳氮比和溶解性有机碳解释了22.6%.水解氮和微生物氮解释了12.3%,速效钾解释了5.7%,表明红壤不同植被下细菌群落碳源利用受土壤性质的影响很大.

| Abstract: | Soil samples under eight vegetation types were collected from the Red Earth Ecosystem Experimental Station to investigate the effect of soil properties on bacterial carbon source utilization using BIOLOG GN plate. The relationships between sixteen soil properties and bacterial carbon source utilization were established by using principle component analysis and regression analysis. The results showed that 54.9% of the variation in bacterial carbon source utilization was explained by seven soil properties, am... |
