摘要/Abstract

摘要： 以草坪为研究对象,研究草坪土壤中丛枝菌根真菌种群的孢子组成、孢子密度、物种丰富度、多样性及其季相变化规律。结果表明,丛枝菌根真菌孢子密度、物种丰富度和多样性指数在一年内随季节变化表现出一定的季相变化规律,三者均在冬季达到最高,在时间节律上与植物群落季相变化不同步;同时分析了气候因素(平均温度、降雨量和日照时间等)对丛枝菌根真菌的影响。结果表明,气候因素对孢子密度、物种丰富度和多样性指数均有显著影响。

Abstract: The study results showed that the spore density,species richness,and diversity index of arbuscular mycorrhizal fungi in a grassland soil had a seasonal variation and reached the maximum in winter,which were not synchronous with the rhythm of plant community.Some climatic factors such as mean temperature,rainfall and sunshine time significantly affected the spore density,species richness and diversity of arbuscular mycorrhizal fungi.

Key words: Cutting system, Population biomass, Leymus chinensis, Koeleria cristata, Artemisia commutata
