Environmental changes were evaluated by sedimentary records in Zhelin Bay, China. High proportion of cysts of heterotrophy indicated an eutrophication trend. The decline of BSi suggested a decreasing diatom productivity during 1990s. Most metals originated from both lithogenic source and human activities. Significant environment changes occurred after 1985, three stages could be referred.
