同安湾潘涂对虾养殖垦区不同形态磷的含量与动态

The contents and dynamics of different forms of phosphorus in shrimp culture area of Pantu, Tong'an Bay, Xiamen

１９９６年５至１９９７年２月对厦门市同安湾潘涂垦区两口虾池及进水渠道不同形态磷的含量与动态进行了 调查。结果显示，虾池的颗粒磷（ＰＰ）含量明显高于邻近内湾，可溶性有机磷（ＤＯＰ）含量略高于内湾，可溶性无 机磷酸盐（ＤＩＰ）含量则明显比邻近内湾的低。虾池中的磷主要以ＰＰ形态存在（７８．２５％），ＤＯＰ、ＤＩＰ含 量较少（ｌ．８２％和６．９３％）；垦区内湾则是以ＰＰ和ＤＩＰ为主（４４．４９％和４６，３９％），ＤＯＰ所占比例最小 （９．１２％）。虾池与垦区内湾不同形态磷的季节变化也存在一定差异。

From May 1996 to Feb. 1997, the contents and dynamics of different forms of phosphorus in two shrimp ponds and the inflow channel in Pantu cultivation area in Tong' an Bay, Xiamen were surveyed. The results showed that the content of particle phosphorus (PP) in shrimp ponds was significantly higher than that in the neighboring bay, while the content of dissolved organic phosphorus (DOP) in shrimp ponds was slightly higher, and the content of dissolved inorganic phosphorus (DIP) was evidently lower than that in the neighboring bay. PP was the main existing form of phosphorus in shrimp ponds (78 ..25 %), the contents of DOP and DIP were lower (14.82% and 6.93%, respectively), while in the neighboring bay phosphorus exists mostly in the forms of PP and DIP (44.49% and 46.39%, respectively), and DOP only constitutes 9.12%. The seasonal variations of the different forms of phosphorus in shrimp ponds are different from those in the neighboring bay.
