研究了云南高山热带山地森林土壤微生物群落的树种效应。位于马来西亚婆罗洲的京那巴鲁。我们调查了微生物组成（脂质分布）和土壤理化参数（pH值，水分。在两种针叶树（Dacrycarpus imbricatus和Dacrydium gracilis）和三种阔叶树（Lithocarpus clementianus、Palaquium rioence和Tristaniopsis clementis）下的顶部5cm土壤中，总C、N和酚类化合物浓度）。我们发现，微生物组成的主要差异是针叶与阔叶之间。土壤微生物生物标志物脂类丰度与土壤pH值、全C和全N相关。结果表明，树种通过影响土壤pH值、全C和全N，对土壤微生物群落有显著影响。(c)2008爱思唯尔有限公司版权所有。
We investigated tree species effects on the soil microbial community in the tropical montane forest on Mt. Kinabalu, in Malaysian Borneo. We investigated microbial composition (lipid profile) and soil physicochemical parameters (pH, moisture. total C, N and phenolics concentration) in top 5-cm soils underneath two conifers (Dacrycarpus imbricatus and Dacrydium gracilis) and three broad-leaves (Lithocarpus clementianus, Palaquium rioence and Tristaniopsis clementis). We found that the primary difference in microbial composition was between conifer versus broad-leaves. The abundance of specific microbial biomarker lipids correlated with soil pH, total C and N. We conclude that tree species have significant impacts on the soil microbial community through their effects on soil pH, total C and N. (c) 2008 Elsevier Ltd. All rights reserved.
