基于河道崩岸现有研究成果,对崩岸类型的划分进行了梳理,进而将河道崩岸的影响因素概括为水流动力条件、河道边界条件,及其他因素3大类,并从数值模拟和概化模型试验2个方面总结了河道崩岸研究的进展。在此基础上,分析讨论了当前河道崩岸机理研究中存在的不足,如未能全面考虑各种因素影响、崩岸数值模拟技术不够完善、概化模型试验精度需进一步提高等。最后,对未来崩岸研究工作的开展,提出了需关注的重点与建议。

我国城市湖泊的生态系统功能下降,城市湖泊富营养化问题也日趋严重。城市湖泊的富营养化通常表现为磷限制,而湖泊沉积物是磷的主要归宿地。研究沉积物中磷的含量及分布特征,对探明其污染状况及湖泊富营养化的控制与治理具有重要的参考意义。洋澜湖作为典型的城市湖泊,近年来存在富营养化问题,以洋澜湖作为研究对象,分析其表层沉积物中的总磷(TP)浓度及空间分布特征,采用单因子指数法对沉积物中磷的污染情况进行评价,并选取3个代表性区域分析沉积物中磷的形态及垂向分布。结果表明,洋澜湖表层沉积物中TP的浓度为528~3568 mg

基于1955—2018年洞庭湖水沙数据,运用Mann-Kendall检验法、双累积曲线等方法分析了洞庭湖近60多年水沙演变特征及其与人类活动的关系。研究结果表明:①受长江荆江段河道变化以及水利枢纽建设等的影响,三口、四水入洞庭湖水沙呈显著下降趋势,其中以三口输沙量的变化最为显著,且受三口水沙变化的影响,城陵矶年径流量与输沙量均呈下降趋势;②1955—2018年,洞庭湖湖盆泥沙淤积量呈显著下降趋势,泥沙淤积量的减小主要与由水利工程建设等人类活动引起的三口输沙量的减小有关;③水利工程建设等人类活动降低了水体中
