摘要
由于修建闸坝等水利工程对河道内水流、悬浮物、底泥等具有强烈的扰动作用,闸控河段水质转化过程呈现出多介质、多相态、多形式的特点。基于水质多相转化机理,分析了不同调度方式下闸控河段的水质迁移转化特点;提出在"水体-悬浮物-底泥-生物体"界面内开展水质多相转化研究的总体思路,推导了能有效描述各种相态水质之间传质过程的数学表达式,进而构建了具有一定物理机制的闸控河段水质多相转化模型,为客观认识水闸调度在水资源保护中所起的作用提供科学依据。
Due to having a strong disturbance to the environmental factors （such as water flow, suspended substance and sediment） caused by sluice operation, the transform process of water quality in reaches controlled by sluice （RCS） shows the characteristics of multi-media, multi-phase and multi-form. Based on the expatiation on multi-phase transform mechanism of water quality, the characteristics of water quality transfer and transform under different regulation modes in RCS is analyzed. And then the overall idea on the research of multi-phase transform of water quality in the water-suspcn sion-sediment-organism interface is put forward, and the multi-phase transform model of water quality in RCS is buih based on the deduction of mathematical expressions which are able to describe the mass transport process among various phase states tion in water of water quality effectively. The research can provide scientific basis for recognizing the value of sluice opera environment protection
