海浪河流域河夹村段细菌群落数量时空分布

本文于2009至2010年对海浪河河夹村段水体及底泥中细菌组成与时1空分布进行研究与分析,结果表明,该流域分离出的细菌隶属于5个细菌菌属,其中微球菌属（Micrococcus）是优势菌属,其次是假单胞菌属（Pseudomonas）和动胶菌属（Zoogloeaitzigsohn）。在时间分布上,水样细菌群落数量最高值出现在2009年5月份,最小值出现在2010年1月份,泥样细菌群落数量最高值出现在2009年5月份,最小值出现在2009年7月份。在空间分布上,水样和泥样细菌群落数量总数在8、9、10号样点高于其它样点一个数量级,但各样点细菌菌属没有明显的差异。

The Spatial and Temporal Distribution of Bacterial Community from Hejia Uillage River Stretch in Hailang River

The present paper analyzed the spatial and temporal distribution of bacterial community from Hejia village river stretch in Hailang river.The results was concluded that the bacteria isolated from above belonged to five bacterial genera,among which Micrococcus was the preponderant genus and followed by Pseudomonas and zoogloea.For the time distribution,the number of bacterial communities from water samples got the highest value in May 2009 and the minimum in January 2010,whereas the number of bacterial communities from soil samples got the highest value in May 2009 and the minimum in July 2009.For the spatial distribution,the total number of bacterial communities from both water and soil samples in 8,9 and 10 points was higher than the others,but the bacterial genera in various points was not significantly different.
