| 摘 要： | 1996年6月至1997年2月，对厦门市潘涂垦区两口虾池及附近内湾不同形态氮的含量与动态进行调查。结果显示虾池的可溶性有机氮（DON）含量明显高于邻近内湾，颗粒有机氮（PN）多数时间也高于内湾，而邻近内湾可溶性无机氮（DIN）含量则明显比池内的高。虾池中的氮主要以DON形态存在（59．76％），DIN，PN含量较少（9．37％和20．87％）；邻近内湾则是以DIN为主（59．97％），其次为DON（29．55％），PN所占比例最小（10．48％）。吓池与邻近内湾不同形态氮的季节变化也存在一定差异。

| Abstract: | From Jun. 1996 to Feb. 1997,the contents and dynamics of the different forms of nitrogen in two shrimp ponds and inflow channel were surveyed in Pantu cultivation area in Xiamen. The results showed the dissolved organic nitrogen (DON) in shrimp ponds was obviously higher than that in the adjacent bay, the content of particle nitrogen (PN) in shrimp ponds was also higher in most time, while the content of dissolved inorganic nitrogen (DIN) was evidently lower than that in the adjacent bay. DON was the main existing form of nitrogen in shrimp ponds (57.76%), the contents of DIN and PN were lower (9.37% and 20.87%);while in the neighboring bay nitrogen exists mostly in DIN (59.97%), then is DON(29.55%),PN only contributes 10.48%. The seasonal variations of the different forms of nitrogen are different between in shrimp ponds and in adjacent bay. |
