摘　　要：水库调蓄显著影响地表水生物地球化学和生态过程,其内部的持留转化机制对颗粒物沉淀再悬浮、营养盐收支、物质输送和循环等意义重大。关于水库对地表水溶质运移的行为缺乏综合讨论。本综述比较了水库地表水中重金属、碳、氮磷营养盐及污染物运移的研究进展,发现水库通过沉淀和转化作用明显减少河流对下游的物质输出,水库不同时期可能会是溶质的"源"和"汇"。但是,关于水库如何影响河流营养物质、重金属等的迁移转化,从而影响河流水生态化学环境、河口和下游的物质流量,其内在反应机理尚需进一步研究。The interception and storage of reservoirs significantly affect the biogeochemical and ecological processes of surface water, and its internal retention and transformation mechanism is of great significance to the precipitation and re-suspension of particulate matter, nutrient balance, material transport and circulation. At present, there is no comprehensive discussion on the solute transport behavior of surface water in reservoirs. This review compares the research progress of the migration of heavy metals, carbon, nitrogen and phosphorus nutrients and pollutants in the surface water of reservoirs. It is found that the reservoir obviously reduces the material output of the river to the downstream through sedimentation and transformation, and the reservoir may be the ″source″ and ″sink″ of solute in different periods. However, the internal reaction mechanism of how the reservoir affects the migration and transformation of river nutrients, heavy metals, etc., thus affecting the river′s water eco-chemical environment, estuary and downstream material flow, needs to be further studied.
