中文摘要：

对闽东南地区的泉州市东湖和西湖不同水域水体中各形态磷进行采样分析，探讨城市湖泊水体中磷的空间分布特征．研究结果表明：东湖和西湖水体中总磷的平均质量浓度分别为0．470，0．203mg·L^-1，而溶解性总磷酸盐分别占总磷的60．2％～87．6％和38．1％～73．2％．这表明东湖水体中磷的主要存在形态是溶解性总磷酸盐，且主要以溶解性正磷酸盐的形式存在，占溶解性总磷酸盐的60％～92％；而西湖溶解性正磷酸盐占溶解性总磷酸盐的34．7％～68．5％．东湖和西湖水体各采样点中，溶解性总磷酸盐与溶解性正磷酸盐有相似的空间分布规律．

英文摘要：

Several types of phosphorus in water from different areas of East and West Lake in Quanzhou were investigated, then their spatial distribution character was discussed. The results suggest that the mean mass fractions of total phosphorus in East Lake and West Lake are 0. 470 mg · L^-1 and 0. 203 mg ·L^-1 , respectively. The dissoluble phosphate in East Lake water accounts for 60. 2%-87. 6% in total phosphorus, while this figure in West Lake is 38. 1%-73. 2%. This indicates that the soluble reactive phosphorus which is the main form in East Lake water accounts for 60%-92% in total dissoluble phosphorus. The soluble reactive phosphorus in West Lake water accounts for 34. 7%-68. 5% in total dissoluble phosphorus. The total dissoluble phosphate and the soluble reactive phosphorus are distribute homologous in each lake water.
