摘要
近年,太湖水污染与富营养化问题依然突出,太湖底泥清淤作为工程治理手段受到广泛关注。通过对太湖底泥分布特征和污染状况、污染源构成和湖泛发生机理的研究,以及已经实施的太湖清淤疏浚效果的分析,表明清淤对改善太湖水质或抑制蓝藻暴发的效果十分有限,且存在诸多问题,以湖泊富营养化治理为目标的太湖底泥大规模清淤疏浚须谨慎决策。
In recent years,water pollution and eutrophication in the Taihu Basin has been severe and the dredging of bottom mud of the Taihu Lake has attracted widespread attention.According to studies on the feature of mud distribution and pollution,and pollution source and spreading mechanism,as well as analysis on the results of cleaning and dredging in the Taihu Lake,it finds that the measure has not shown an obvious result for improvement of water quality and reduction of blue algae.Thus it is concluded that cautions need to be given to large-scale dredging of bottom mud of the Taihu Lake.
