中国幅源辽阔,南北跨度大,在自然气候环境的影响和人为因素的干扰下,不同地区土壤养分和土壤微生物种类、数量存在显著的空间差异,进而造成了土壤质量的空间差异。为了解中国东部天然林土壤养分和微生物多样性空间分布规律,本研究依据水热梯度变化特征采集了16个自然保护区52个典型森林土壤样方,测定了土壤养分和微生物指标,包括pH值、有机碳、有机质、总碳、总氮、总磷、总钾、速效磷、速效钾、碱解氮、土壤微生物宏基因组丰度和香农多样性指数。研究发现,中国东部森林土壤养分含量较高,空间差异大,宏基因组香农多样性指数变异系数为0.03,属弱变异,速效磷变异系数为1.17,属强变异。土壤养分(除...

China covers a territorial scope at large scale with a long distance from north to south. There exist obvious spatial differences between soil nutrition, and the species and amount of soil microorganisms under the impacts of climatic and anthropogenic factors, which then cause to the spatial differences of soil quality. In order to explore the spatial distribution of soil nutrient and microbial diversity of the virgin forests in the eastern China, the soil samples were collected from 16 natural reserves including 52 typical forests, basing on the characteristics of the changes of water thermal...
