The results indicated that on average the rank order of the concentrations of different nitrogen species in overlying water and porewater was organic nitrogen>ammonia>nitrate; the main form of inorganic nitrogen in sediments was of ammonia, and the submer

结果表明：总体上，上覆水和间隙水中不同形态氮含量的顺序为有机氮＞氨氮＞硝态氮；沉积物中可交换态无机氮以氨氮为主，沉水植物的存在并没有改变这一格局。
