摘要
西小磨 1996年和 1997年 7～ 8月期间 2 4 8个调查数据显示 ,NO2 N浓度范围和平均值沿岸分别是 1 3～ 2 2 2 μg/L和 5 7μg/L ,虾池分别是 1 1～ 13 5 μg/L和 6 6 μg/L。NO3 N范围和平均值沿岸分别是 1 3～ 2 14 2 μg/L和 70 7μg/L ,虾池是 2 3～ 15 9 7μg/L和 36 1μg/L。NH4 N范围和平均值沿岸分别是未检出～ 37.9μg/L和 6 .7μg/L ,虾池是未检出～ 10 6 8μg/L和 10 8μg/L。PO4 P范围和平均值沿岸分别是 1 6～ 11 0 μg/L和 4 9μg/L ,虾池是 0 74～ 18 8μg/L和 4 0 μg/L。虾池中氮、磷的特点是浓度上限值和平均值远较非养殖的远岸外海区高 ,氮、磷的变化趋势并不总是一致。降雨能导致虾池NO3 N和NO2 N的大幅度提高 ,但不能影响PO4 P和NH4 N。
The 248 data collected during July to August in 1996 and 1997 show that the concentration range and average of NO 2 N is 1 3 to 22 2 μg/L and 5 7 μg/L respectively in the coast, and 1 1～13 5 μg/L and 6.6 μg/L in the shrimp pond respectively; the concentration range and average of NO 3 N is 1.3～214 2 μg/L and 70 7 μg/L respectively in the coast, and 2 3～159 7 μg/L and 36 1 μg/L in the shrimp pond respectively; the concentration range and average of NH 4 N is no deteced～37 9 μg/L and 6 7 μg/L respectively in the coast, and no detected～106.8 μg/L and 10.8 μg/L in the shrimp pond respectively; the concentration range and average of PO 4 P is 1 6～11 0 μg/L and 4 9 μg/L respectively in the coast, and 0.74～18.8 μg/L and 4.0 μg/L in the shrimp pond respectively. The character of nitrogen and phosphorus in shrimp pond is that the up limit of the concentration and the average are far more higher than those of the offshore; and the changing trend is not always same between nitrate and phosphorus; and the concentrations of NO 3 N and NO 2 N increase largely after raining, but those of PO 4 P and NH 4 N are not affected.
