疏浚对大连湾生物可利用磷的水体浓度和沉积物-水界面交换通量的影响
DOI: 10.3724/SP.J.1145.2012.00426, PP. 426-431
Keywords: 疏浚,feo/cam膜,生物可利用磷,交换通量,大连湾
Abstract:
利用feo/cam复合膜对大连湾已疏浚区与疏浚影响区海水水体中生物可利用磷（bio-availablephosphorus，bap）浓度和水质指标进行调查，并通过实验室培养法、间隙水浓度梯度估算法和薄膜扩散梯度技术（diffusivegradientsinthinfilmstechnique，dgt）法分别测定沉积物-水界面间bap交换通量.结果表明，由于受到调查海区附近正在进行的疏浚工程的影响，疏浚影响区水体中浊度和悬浮物含量平均值高于已疏浚区，且疏浚影响区水体中bap的平均浓度（22.2μgl-1）高于已疏浚水体（19.5μgl-1）；而疏浚影响区叶绿素a和溶解氧的浓度明显低于已疏浚区.沉积物-水界面间bap交换通量研究结果显示，bap主要由沉积物向上覆水中扩散，沉积物是bap交换的源；间隙水浓度梯度估算法和dgt法测定的bap交换通量相似，但远低于实验室培养法测定值；bap在已疏浚区沉积物-水界面间的交换通量小于疏浚影响区，说明在一定时间内疏浚可以减弱沉积物内源磷的释放.
