China Environmental Science, 2013,33(S1)：66~73 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 9 3 8 10 3 ~3.68×10 cells/m and 4.85×10 ~1.37×10 cells/m ; 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.
