Abstract:

采用荧光显微技术,报道了春季(2006年4月)海洋病毒丰度在黄海的空间分布,分析了病毒丰度与细菌丰度、叶绿素a浓度、温度和盐度的相关关系。研究结果表明,黄海表层水中病毒丰度的变化范围为1.08×107~9.90×107个/mL,平均值是5.62×107个/mL±2.28×107个/mL,细菌丰度的变化范围为0.01×107~0.16×107个/mL,平均值是0.07×107个/mL±0.03×107个/mL,病毒丰度大于细菌丰度两个数量级。叶绿素a浓度表层的变化范围为0.09~4.94μg/L,平均值是0.75μg/L±0.84μg/L,最高值出现在长江口附近。通过相关性分析,在黄海春季,细菌可能控制着病毒的空间分布,并且病毒的空间分布受盐度影响较小,受温度影响较大。
