摘　　要：以红枫湖水库为研究对象,测定10个点位不同深度水体中溶解硅质量浓度并初步探讨其垂直分布特征.结果表明:(1)红枫湖水库水体溶解硅大体呈现出表层质量浓度低,底层质量浓度高的垂向分布特征,北湖湖心、坝前积累区和南湖湖心除外;(2)河口和坝前积累区溶解硅质量浓度平均值相对较高,而过渡区和水流下游区相对较低.红枫湖水库水体溶解硅质量浓度的分布特征与硅溶解时间和迁移沉积有关,还可能与水库地形、水文状态、采样点位和水体污染等因素有关.The vertical characteristics of the dissolved silica content(DSi)are studied by measuring ten different depth sites of Hongfeng Reservoir.The results showed that:(1)DSi in the lower layer of the lake is generally higher than in the upper layer at most sites,except the center of the North and South Lake,and the pre-dam accumulation area;(2)the average value of DSi in water column is relatively high in estuarine and pre-dam accumulation areas,and relatively low in the transition zone and downstream areas of the flow.These distribution characteristics of DSi at Hongfeng Reservoir may be related to the time of silica dissolution and migrated deposition,as well as reservoir topography,hydrological conditions,sampling sites,water pollution and other factors.
