摘　　要：于2011年10月和2012年4月通过走航对大亚湾海域开展了秋季、春季水生态环境调查.调查结果显示,秋季和春季浮游植物分别鉴定出20属28种及19属34种,数量分别在7.7×108~3.68×109cells/m3和4.85×108~1.37×1010cells/m3之间,多样性指数(H′)分别为0.27~2.06和0.86~2.16,均匀度(J)分别为0.17~0.83和0.31~0.84;秋季和春季浮游动物分别鉴定出67种和60种,数量分别在2260~82035ind/m3和21210~2072910ind/m3之间,多样性指数分别为1.52~2.29和0.14~2.10,均匀度分别为0.45~0.69和0.04~0.63.Daya Bay is one of a series of large bays along the southern coast of China. Two investigations were conducted on the aquatic ecological environment in Daya Bay, in October 2011(autumn) and April 2012(spring). A total of 20 genera and 28species in autumn and 19 genera and 34species in spring of phytoplankton were identified. In autumn and spring,the amount were respectively between 7.7×108~3.68×109cells/m3 and 4.85×108~1.37×1010 cells/m3; diversity were respectively between 0.27~2.06 and 0.86~2.16; evenness were respectively between 0.17~0.83 and 0.31~0.84. A total of 67 species in autumn and 60 species in spring of zooplankton were identified. In autumn and spring,the amount were respectively between 2260~82035 ind/m3 and 21210~2072910 ind/m3; diversity were respectively between1.52~2.29 and 0.14~2.10; evenness were respectively between 0.45~0.69 and 0.04~0.63.
