春夏季漳泽水库浮游动物群落特征及水质评价
|
摘要
2014年和2015年春(5月)、夏(8月)季对漳泽水库浮游动物进行了4次调查,共检出浮游动物53种(原生动物20种,轮虫18种,枝角类7种,桡足类8种)。浮游动物物种数夏季较多,2014年和2015年夏季分别为34种和35种;春季较少,分别为17种和21种。2015年夏季浮游动物总丰度最高,为24 396个/L;2014年春季浮游动物总丰度较低;为1 435个/L;漳泽水库浮游动物丰度主体为原生动物和轮虫。四次调查浮游动物Shannon-Weaver多样性指数变化范围为2.25~3.60,判断水质为轻污染至清洁状态,综合营养状态指数最终初步确定漳泽水库水质为中-富营养型。
Four times of investigations were carried out on zooplankton in the Zhangze Reservoir in 2014 and 2015(May)and in summer(August). 53 species of zooplankton were detected(20 protozoans,18 rotifers,7 Cladocera and 8 copepods). There were more species of zooplankton in summer,and 34 species and 35 species in summer in 2014 and2015 respectively,and 17 species and 21 species in spring. In the summer of 2015,the total abundance of zooplankton was the highest,which was 24 396/L;the total abundance of zooplankton in the spring of 2014 was lower,which was1 435;the main abundance communities of zooplankton in the Zhangze Reservoir were protozoa and rotifer. In the four times of survey,the Shannon-Weaver diversity index of zooplankton varied from 2.25 to 3.60. which determined that water quality was light pollution to clean state. The comprehensive nutritional status index finally determines that the water quality of Zhangze Reservoir is medium-rich.
