| 根据前文提出的闸控河段水质多相转化模型,设置不同的水闸调度情景,进一步开展在不同水闸调度情景下的水质浓度数值模拟;引入“贡献率”的概念,定量评估水闸调度在水质多相转化过程中所起的作用大小,分析水闸调度对水体中各种反应机制的驱动作用,识别其中的主导反应机制。通过分析发现:水闸调控对水质多相转化的贡献率随着闸门调度方式的改变而变化,且水质转化表现出不同的主导反应机制;当闸门维持小开度放水时,吸附、沉降等作用的主导性显著增强,而闸门维持大开度放水时,解吸、再悬浮等作用主导性显著增强;不同反应之间的主导性强弱在闸门调控方式的改变下交替变化。 |

| Abstract:According to the multi-phase transformation model of water quality proposed in the preceding paper, different scheduling scenarios of sluice were set to further develop the water quality concentration numerical simulation. Then the concept of“contribution rate” was introduced, which can quantitatively evaluate the effect of sluice scheduling in the process of multi-phase transformation of water quality, and analyze the driver effect of different scheduling schemes on various reaction mechanisms and identify the leading reaction mechanism. The results show that contribution rate of sluice scheduling for multi-phase transformation of water quality changes with sluice scheduling methods changing, and water quality transformation showed different leading reaction mechanisms. When the sluice gate is in a small opening, the dominant role of adsorption and sedimentation will be significantly enhanced. On the contrary,the leading role of desorption and resuspension will be enhanced when the sluice gate in a large opening. And the leading role of different reaction changes alternately with sluice scheduling methods changing. |
