中文摘要：

通过对泉州城区浅水湖泊水体生物有效磷及叶绿素a的采样分析，探讨水体中生物有效磷的分布特征及其与叶绿素a的相关性，结果表明：泉州东湖水体生物有效磷浓度在0．25mg·l^-1—0．38mg·l^-1之间，西湖水体生物有效磷浓度在0．05mg·l^-1—0．10mg·l^-1之间．东、西湖溶解态生物有效磷和颗粒态生物有效磷均与总生物有效磷的浓度有着相似的空间分布趋势．东湖水体叶绿素a与西湖水体叶绿素a含量相差悬殊．除东湖颗粒态生物有效磷之外，东湖和西湖各种生物有效磷浓度与叶绿素a含量之间有显著的线性相关关系．湖泊周边的地形、风浪和船只运行扰动是影响生物有效磷浓度和叶绿素a含量的重要原因。

英文摘要：

Based on the analyses of samples collected from Donghu lake and Xihu lake in the southeastern Quanzhou of Fujian province, the distribution characteristics of bioavailable phosphorus （BAP） and its correlation with chlorophyll-a have been studied in this article. The study results are as follows： the concentration of BAP in Donghu lake and Xihua lake ranges respectively from 0. 25 mg·l^-1 to 0. 38mg·l^-1, and from 0. 05mg·l^-1to 0. 10mg·l^-1; Both in Donghu lake and Xihu lake, the dissolved bioavailable phosphorus （FeO-DP） and particulate bioavailable phosphorus （FeO-PP） are similar to the whole bioavailable phosphorus （FeO-P） in terms of spatial distribution state. There is a big difference in the amount of chlorophyll-a between Donghu lake and Xihu lake. Except FeO-PP in Donghu lake, there are significant linear correlations between BAP and chlorophyll-a. The peripheral geography characteristics, wind-induced waves and disturbances from boats have important influences on the distribution of BAP and ehlorophyll-a in urban shallow lakes in Quanzhou, Fujian.
