摘　　要：对青草沙水库底泥中的TN、TP和有机碳含量进行分析与评价。结果表明:青草沙库区内TN、TP、有机碳在不同采样点位的浓度分布趋势是基本一致的;其中,库尾的1#、2#点位呈现略高的浓度,库首12#点位浓度最低,此分布特征主要与库内藻类沉降及水动力条件有关。根据有机污染指数评价法,青草沙水库库尾2#点位属于尚清洁区域,12#属于清洁区域,其他点位有机污染程度位于两者之间,属于较清洁区域。The concentration of total nitrogen,total phosphorus and organic carbon in the sediment of Qingcaosha Reservoir were analyzed and evaluated.The results showed that concentration distribution of total nitrogen,total phosphorus and organic carbon in different areas of the reservoir was basically the same.The 1#and 2#points showed a slightly higher concentration,and the 12#point was the lowest.Distribution characteristics were mainly related to algae sedimentation and hydrodynamic conditions in the reservoir.According to organic pollution index evaluation method,the 2#point of Qingcaosha Reservoir is a still clean area,12#point belongs to the clean area,and the other points is between the two,which belongs to a cleaner area.
