摘要/Abstract

摘要： 为了科学评估引水调度的生态水文效应,以大东湖水网中的东沙湖为典型研究对象,从控制水体富营养化的角度,选取最大流速、平均流速、流速＞0.01 m/s的水面比例、水龄、换水率共5个指标作为关键生态水文要素,通过构建的东沙湖水动力模型,模拟得到引水调度前、后共计6种工况下,东沙湖流速、水龄的空间分布情况,统计得到各工况下的关键生态水文要素值。对比结果表明:引水调度后,东沙湖最大流速、平均流速、流速＞0.01 m/s水面比例、换水率等生态水文要素均明显增加,水龄明显降低。研究成果表明引水调度能有效影响东沙湖生态水文条件,可为开展湖泊生态调度提供参考依据。

Abstract: The aim of this study is to evaluate the eco-hydrological effect of water diversion and dispatching with Dongsha Lake of the Donghu Lakes Network as a typical research object. We selected five key eco-hydrological elements, namely, maximum flow velocity, average flow velocity, water surface ratio of flow velocity exceeding 0.01 m/s, water age, and water exchange rate from the perspective of controlling water eutrophication. By constructing the Dongsha Lake hydrodynamic model, we simulated the spatial distribution of flow velocity and water age under six conditions before and after the diversion and dispatching, and obtained the values of key eco-hydrological elements. Results unveiled that the maximum flow velocity, average flow velocity, water surface ratio of flow velocity exceeding 0.01 m/s and water exchange rate increased remarkably, while water age reduced markedly. Diversion and dispatching effectively affected the eco-hydrological conditions of the Dongsha Lake. The research finding offers a reference for ecological dispatching.
