于 2013-2021 年 1、4、7、10 月,在澳门路氹城生态保护区设置 2 个采样区,各 3 个采样点,调查分析浮游动物群落结构的时空变化,并初步评估水体受扰动状况.结果表明:在澳门路氹城生态保护区共鉴定出 171种浮游动物(含 9 类浮游幼虫),其中一区鉴定出 156 种,二区鉴定出 116 种;浮游动物分属于 8 个类群,主要优势类群为轮虫(57种)、桡足类(48种)和纤毛虫(33种);一区浮游动物丰度为 6.00～240.33 ind/L,平均为(59.27±58.39)ind/L,二区浮游动物丰度为 3.00～62.58 ind/L,平均为(19.20±16.82)ind/L;一区和二区浮游动物群落结构区域差异显著,一区物种数和丰度显著大于二区的,一区的Shannon-Winner多样性指数、Margalef丰富度指数和Pielou均匀度指数均值显著小于二区的,一区浮游动物丰度年际变化波动大于二区的,可见一区环境较二区更加敏感,一区受人类活动影响较大;2013-2016年浮游动物优势种主要为轮虫(污染指示种),2017-2021 年浮游动物优势种主要为桡足类(非污染指示种),更替率为 100%,除一区 2017-2021 年的 Shannon-Winner 多样性指数小于2013-2016年的外,两区域其余生物多样性指数均大于 2013-2016年的,说明保护区水质有所改善.
Two sampling zones and six sampling points were set up in the Macao Cotai Ecological Reserve in January,April,July and October 2013-2021 to investigate and analyze the spatial and temporal changes in the zooplankton community structure,and to make a preliminary assessment of the disturbed status of the water body.The results showed that 171 species of zooplankton(including 9 types of zooplankton larvae)were identified in the Cotai Ecological Reserve,of which 156 species were identified in Zone I and 116 species were identified in Zone II.The zooplankton belonged to 8 taxa,and the main dominant taxa were rotifers(57 species),copepods(48 species),and ciliates(33 species);the abundances of the zooplankton in Zone I ranged from 6.00-240.33 ind/L with an average of(59.27±58.39)ind/L,and zooplankton abundance in Zone II ranged from 3.00 to 62.58 ind/L,with an average of(19.20±16.82)ind/L.Regional differences in the structure of zooplankton communities in Zones I and II were significant,with the number of species and abundance in Zone I significantly greater than those in Zone II.The Shannon-Winner diversity index,the Margalef richness index,and Pielou evenness index in Zone I were significantly smaller than those in Zone II,and the interannual variation of zooplankton abundance in Zone I is larger than that in Zone II,which shows that the environment of Zone I is more sensitive than that of Zone II,and that Zone I is more affected by human activities.The dominant zooplankton species was mainly rotifers(pollution indicator species)in 2013-2016,and the dominant zooplankton species was mainly copepods(non-pollution indicator species)in 2017-2021,with a turnover rate of 100%.Except for Shannon-Winner diversity index of Zone I in 2017-2021,which was less than that in 2013-2016,the biodiversity indices of the two zones were greater than those of 2013-2016,which suggests that there has been an improvement in water quality of the reserve.
