以辽东山地蒙古栎山杨林、槭树蒙古栎林、落叶松人工林、山杨林和白桦山杨林5种水源林为研究对象,分析物种组成、多样性、丰富度等因素对土壤有机碳、微生物量碳和土壤可溶性有机碳含量特征的影响。结果显示:土壤有机碳和可溶性有机碳含量均表现为落叶松人工林最高,山杨林最低,微生物量碳含量表现为落叶松人工林最低;从土层上看,0~10 cm土壤有机碳、可溶性有机碳和微生物量碳含量均显著高于>10~30 cm土层的含量;土壤微生物量碳含量与多样性和丰富度呈正相关,并且乔木多样性和丰富度对土壤微生物量碳含量的影响大于灌木和草本;土壤有机碳和可溶性有机碳含量与灌木多样性和丰富度均呈显著负相关,并...

In five types forest, Quercus mongolicaand–Populus davidiana, Acer ukurunduense–Quercus mongolicaand, Larix kaempferi, Populus davidiana and Betula platyphylla–Populus davidiana forests, in headwater catchment of eastern mountainous of Liaoning province, we studied the effects of species composition, diversity and richness factors on the contents of soil organic carbon, microbial biomass carbon and soil soluble organic carbon. Our results showed that, the contents of soil organic carbon, dissolved organic carbon were the highest in Larix kae...
