摘　　要：以青藏高原不同海拔湖泊湖水为研究材料,以低海拔湖泊湖水作为对照,通过微生物的分离、培养、统计、分析等方法,对青藏高原不同海拔的青海湖(3 260 m)和纳木错湖(4 718 m)湖水中可培养微生物数量的季节性变化进行了研究,探讨海拔梯度造成的气候环境因素对微生物数量变化的影响。结果表明,青海湖和纳木错湖湖水中可培养微生物多样性呈明显的季节性变化,并于8月份达到最大值,可培养微生物多样性与光照、温度等环境因子显著相关。The water samples,collected from different altitude lakes,Qinghai Lake（3 260 m）and Namco Lake（4 718 m）in Qinghai-Tibet Plateau,were investigated to study the seasonal change of the diversity of culturable microorganisms by microorganisms isolation and culture methods,while the low altitude lake as a control in the study.It is aimed at exploring the impact of environmental factors to the diversity of microbes,due to an altitudinal gradient.The results showed that the diversity of culturable microbes presented seasonal changes in Qinghai Lake and Namco Lake,which reached the maximum in August.There was significant correlation between the diversity of culturable microbes and environmental factors,such as light and temperature.
