摘要: |
湖泊底泥的运动过程产生内源污染,加剧湖泊生态环境的恶化.研究湖泊底泥在波浪作用下的输沙规律,可为研究湖泊的水质变化成因及生态环境治理提供参考依据.利用大型波浪水槽,在波浪作用条件下对太湖、龙感湖、巢湖的底泥进行了起动和输沙试验,对多组波浪水文条件下湖泊底泥的输沙试验结果进行分析,详细地阐述了太湖、龙感湖、巢湖底泥在波浪作用下的输沙变化规律.分析整理试验数据,得出输沙率变化公式,为3个湖泊的水质变化成因分析及生态环境治理提供参考依据. |

Abstract: |
Inter-sourced pollution coming from lake sediment movement has aggravated deterioration of the ecological environment. Sediment transport rate under the lake wave movement provides reference for investigating causes of lake water quality change and ecological environment governance. Sediment transporting experiments from Lakes Taihu, Longgan and Chaohu under wave movements were performed in laboratory wave tanks. The results of silt-clay variations under multi-group wave conditions in the lake were described in detail and then analyzed for the three lakes. The formula of the sediment transporting rate was obtained by analyzing experimental data. These would give reference for causes of water quality change and ecological environment governance. |
