| 2004年6月、9月、12月及2005年3月于千岛湖温馨岛站点(29°38′10.5″N,119°01′54.1″E)进行浮游甲壳动物垂直分布分层采样,分析千岛湖浮游甲壳动物的垂直分布特征及优势种昼夜垂直移动状况。结果显示,千岛湖浮游甲壳动物主要分布在10～21 m水层,不同季节中心水层分布深度12月>9月>6月>3月;浮游动物昼夜垂直移动春(3月)、夏(6月)两季幅度较大,秋(9月)、冬(12月)季节幅度较小;浮游甲壳动物优势种在各个水层都有分布,密集区大都集中在中上水层(10～21 m),不同种类昼夜垂直移动幅度有所不同;昼夜垂直移动显著的种类有特异荡镖水蚤(Neutrodiaptanus incongruens)、近邻剑水蚤(Cyclops vicinus)、球状许水蚤(Schmackeria forbesi)、透明溞(Daphnia hyaline)、长额象鼻溞(Bosmina longirostris),不显著的种类为右突新镖水蚤(Neodiaptomus schmackeri)、短尾秀体溞(Diaphanosoma brachyurum)。光照、温度、饵料是影响千岛湖浮游甲壳动物垂直分布及昼夜垂直移动的主要因素。 |

| The vertical distribution and vertical migration of dominant crustacean species was studied by sampling water at different depths at the Wenxin Island site(29°38′10.5″N,119°01′54.1″E) in Qiandao Lake in June,September and December of 2004 and March of 2005.The planktonic crustaceans dominantly distributed at the depth of 10-21 meter from the surface.Different seasons had different The distribution depths of planktonic crustaceans varied seasonally and they sampled from deep to shallow in December,September,June and March.The vertical distribution range was greater in spring and summer than that was in autumn and winter.The dominant species of planktonic crustaceans mainly distributed in the upper middlewater depth(10-21 m)though they were found at all the water samples.The ranges of the vertical distribution varied with species and time.An obviously diel vertical migration was detected in species Neutrodiaptanus incongruens,Cyclops vicinus,Schmackeria forbesi,Daphnia hyaline and Bosmina longirostris.The trend of vertical movement in Neodiaptomus schmackeri,Diaphanosoma brachyurum was not identified clearly.Illumination,temperature and diet resource were the principal environmental factors driving the diel vertical migration. |
