太湖悬浮物分布的现场监测研究

于2005年8月25日至8月28日对太湖进行现场监测,得到了太湖梅梁湾到大太湖的悬浮物、浊度数据,分析得出:(1)光照强度较高时,对应于微囊藻峰值的出现,浊度在水深0.5m处出现最高值,光照强度较弱时,浊度的分布在垂直方向上趋于均匀;(2)悬浮物浓度与浊度具有较高的相关性,悬浮物浓度值可以用浊度的测定值换算得到;(3)河流流入、风浪条件和湖内藻类繁殖等影响着太湖悬浮物的垂直和纵向空间分布,出现梅梁湾到大太湖不同的悬浮物垂直和纵向分布。

Field Monitoring of Distribution of Suspended Solid in Taihu Lake

The data of suspended solid and turbidity from Meiliang bay to the center of Taihu Lake were obtained by field monitoring from 25th August to 28th August in 2005.The results show that:(1) Corresponding to high solar radiation,turbidity in the depth of 0.5 meter reaches the maximum,which is related to the peak of algal bloom;when solar radiation is relatively weak,the vertical distribution of suspended solid is rather uniform;(2) The suspended solid and turbidity have high correlation,the concentration of suspended solid can be calculated with turbidity value;(3) River inflow,wind and wave,suspension and propagation of algal influence vertical and longitudinal distribution of suspended solid in Taihu Lake,resulting in different distribution of suspended solid from Meiliang bay to the center of Taihu Lake.
