摘要采用传统采样和薄膜扩散梯度技术(DGT),分析了春夏季巢湖西北部湖滨上覆水、间隙水及沉积物中磷形态和DGT有效态磷铁(DGT-P、DGT-Fe)的动态变化及扩散通量.结果表明,初夏季(6月)湖滨上覆水磷含量显著降低,可能源于藻类生长吸收营养盐;而间隙水磷形态含量季节差异显著.巢湖西北部湖滨沉积物无机磷主要为自生磷(Auth-P),占无机磷(IP)比例为19.7%~61.3%.湖滨带消落区(S1、S2)沉积物磷含量明显低于堤坝隔离区(S3),但受有机质水平、水动力扰动等因素影响,具有更高的磷释放潜力;夏季沉积物内源磷释放潜力高于春季.DGT-P和DGT-Fe的相关分析结果表明,湖滨带消落区沉积物内源磷释放主要受控于铁结合态磷还原过程,而堤坝隔离区沉积物受铁磷循环调控作用较弱.

Abstract：By using the traditional manual sampling method and diffusive gradients in thin films technique (DGT), we analyzed the phosphorus species in overlying water, interstitial water, and sediment, and DGT-labile phosphorus (DGT-P) and DGT-labile iron (DGT-Fe) in interstitial water, to investigate the dynamics and diffusion flux of phosphorus in the northwestern lakeshore of Chaohu Lake during the spring and summer seasons. Significant decrease of phosphorus in overlying water in early summer was likely due to its rapid uptake by algae. While significant seasonal variations of phosphorus species in interstitial waters were observed. Authigenic phosphorus was the primary form of inorganic phosphorus in the lakeshore sediments. Lower level phosphorus but higher release potential from sediments in the water-level fluctuation zone (S1, S2) in northwestern Chaohu Lake were observed in contrast to those in the dam isolation zone (S3), due to their different level of organic matter and hydrodynamic disturbance. The release potential of endogenous phosphorus from sediments in summer is higher than that in spring. Correlation analysis between DGT-P and DGT-Fe indicated that the release of endogenous phosphorus from sediments in water-level fluctuation zone is mediated mainly through the iron-bound phosphorus reduction, while those in S3 is weak.
