Cluster Analysis on the Phytoplankton Distribution in the Front Sea of Qingdao

Based on the ecological survey data in the front sea of Qingdao from May 2005 to February 2006, the phytoplankton distribution and its community characters are analysized. With use of cluster analysis, the similarity of the distribution of phytoplankton in all the survey stations has been calculated. In order to demonstrate the similar area more intuitionistic, the spatial distributions of different phytoplankton area in spring, summer, autumn and winter have been given respectively.
