Nitrogen nutrients in Zhelin bay in the May 2000-May 2001 were measured. The results showed that the contents of nitrogen nutrients decreased gradually from the inner bay to the out bay, and the contents in the west of the bay were higher than that of east. Nitrate was the mainly form of dissolved inorganic nitrogen in Zhelin bay. The correlation of ammonia vs. salinity was rather poor and the data showed apparently non-conservative behavior. Nitrate was closely conservative in most case and nitrite exhibited marked biological removal at intermediate.
