摘要: 研究了厦门市石兜-坂头水库中悬浮颗粒物磷形态的分布特征,并分析了各形态磷与水体中叶绿素a的相关性。研究表明,2个库区悬浮颗粒物中的磷主要存在形态为无机磷,占总磷的比例分别为77.9%~87.5%和81.2%~88.1%。从各形态的含量来看,2库区均为Fe/Al-P>Ca-P>OP,其中Fe/Al-P浓度分布整体呈现从近岸边至库心处逐渐降低的趋势,Ca-P受空间变化影响最小。石兜-坂头水库悬浮颗粒物中各形态的磷之间均呈极显著相关性,水体中蓝藻、绿藻中叶绿素a的含量与悬浮颗粒物中的Fe/Al-P、Ca-P、IP浓度均呈正相关,与OP浓度则呈负相关。

Abstract: This paper studied the distribution patterns of phosphorus (P) forms in suspended particulates in Shidou-Bantou reservoir, Xiamen, and analyzed their relationships with the chlorophyll a content in the water body. In the suspended particulates in Shidou and Bantou sections, inorganic phosphorus (IP) was the major P form, occupying 77..9%-87.5% and 81.2%-88.1% of the total P, respectively. The abundance of different P forms was in the order of Fe/Al-P > Ca-P > OP, among which, the abundance of Fe/Al-P showed a gradient distribution, i.e., decreased from near-shore to the centre, while that of Ca-P had the least spatial differentiation. There existed significant correlations among the P forms, and IP, Fe/Al-P, and Ca-P were positively correlated while OP was negatively correlated with the chlorophyll a content of Cyanophyta and Chlorophyta.
