| 摘 要： | 调查结果表明，乳山湾东流区化学需氧量(COD)浓度较低，均低于2mg／L。无机氮浓度较高，5月和8月无机氮的平均值分别为0．32、0．39mg／L，5月无机氮组成以硝酸氮(NO3-N)为主，8月则以氨氮(NH4-N)为主。5月和8月无机磷的平均值分别为0．015、0．035mg／L，IN／IP比值较高，平均值分别为74和25。乳山湾东流区处于富营养化水平。

| Abstract: | In May and Aug. 2002, we investigated the distributions and variations of COD, nitrogen and phosphorous nutrients in Rushan Bay. The results showed that the concentrations of COD were lower than 2 mg/L in both investigations. The mean concentrations of nitrogen and phosphorous nutrients were 0.32 mg/L and 0.015 mg/L in May, and 0.39 mg/L and 5 mg/L in Aug., respectively. The major form of dissolved inorganic nitrogen was nitrate in May; ammonia in August. The mean value of IN/IP was 74 in May; 25 in August. The nutrient status of the east area of Rushan Bay was eutrophied. |
