| 摘 要： | 采用高通量454焦磷酸测序方法对宁波沿海2个重点排污口、8个一般排污口的20个站位水样进行分析,得到2011年的3月、5月、8月和10月份各排污口蓝藻和含叶绿体单细胞生物的分布情况。研究结果表明:宁波沿海陆源排污口中含叶绿体单细胞生物数量最多,占91.857%,包括眼虫门(Euglenozoa)、绿藻门(Chlorophyta)、隐藻门(Cryptophyta)生物。其中主要为眼虫门的裸藻纲(Euglenoidea)生物占90.08%。蓝藻门的集球藻目(Synechococcophycideae)和颤藻亚目(Oscillatoriophycideae)含量相对较多,分别占5.70%和1.79%;排污口中裸藻纲生物数量季节性差异比较大,3月份、8月份数量相对较多,5月份和10月份较少,推测这类生物的数量与季节性温度变化有关;各排污口污染物、这两类生物检出量和种类有一定差异,在氮磷含量高的排污口(如S9号)其检出量并不高,推测检出量与排污口的主要污染物中氨氮含量没有直接关系,可能受氮磷比的影响。

| Abstract: | Water samples were collected at 20 sites spread across 10 sewage outlets, two key sewage outlets, and eight general sewage outlets in Ningbo City during March, May, August, and October of 2011. Research results showed that: the Chloroplast in the largest number of export accounted for 91.857%. The amount of the Synechococcophycideae and Oscillatoriophycideae were relatively more, respectively accounting for 5.704% and 1.787%. The Chloroplast number in different season was various, relatively large in March and August, relatively small in October and May. The number of Chloroplast was related to the seasonal temperature change. There were some differences in the amount and types of pollutants in the sewage outfall. Although the sewage outfall (such as S9) exported the high nitrogen and phosphorus content, the amount of cyanobacteria detected was not high, so there was no direct relationship between the amount of cyanobacteria and the content of nitrogen and phosphorus in the sewage outlet. We speculated that the amount of cyanobacteria was affected by the ratio of nitrogen and phosphorus rather than the content of these. And different cyanobacteria species need the nitrogen and phosphorus ratio. |
