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.
