- 摘要：于2003年8月下旬对黄河口及邻近海域进行了十船连续同步27h采样调查,分析了调查区域的溶解态无机磷、有机磷、总磷的平面分布、断面分布、时间分布特征.结果表明,在调查区域内,溶解态无机磷浓度很低,而溶解态有机磷浓度较高(占溶解态总磷的85%以上),是溶解态总磷的主要组成部分.各形态磷的平面分布、断面分布均呈现出由河口向邻近海域降低的趋势,溶解态总磷、溶解态有机磷梯度变化较溶解态无机磷更为明显;潮汐对河口浅水区的各形态磷浓度影响较大,对邻近调查海域的影响不明显.
- Abstract：10-boats-synchro-27-hour survey was carried out in the Yellow River estuary and its adjacent water in August,2003. The distribution and change of dissolved inorganic phosphorus, dissolved organic phosphorus, dissolved total phosphorus were studied. The results showed that the concentration of dissolved inorganic phosphorus was very low. The dissolved organic phosphorus was the main component of dissolved total phosphorus,with the percentage above 85%. The concentrations of each kind of phosphorus decreased greatly from the estuary to the adjacent water. The change of gradient of DTP、DOPwas much larger than that of DIP. The tide in the Yellow River estuary greatly influenced the concentration of each kinds of phosphorus, while the affection was not obvious in the adjacent water.
