Abstract 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.
