摘要
对 2002年 10月至 2003年 1月期间太湖全湖 223个监测点不同深度采集的共 583个底质样品测定的有机质和总磷含量数据进行了分析.分析表明,不同深度处底泥总磷含量平均值相差不大.除第六层以外,不同深度处底泥总磷含量最大值相差也不大.综合前人资料,比较可知, 20世纪 80年代以来太湖底泥表层沉积物总磷含量平均值变化不大,但最大值逐次增加.研究还分析了底泥总磷含量与有机质含量相关性特点.
OM and TP contents data are evaluated for 583 bottom mud samples collected from different depths of 223 sites in Lake Taihu during Oct.2002—Jan.2003.The maximum TP contents appeared at the bottom surface layer.The analysis shows that the average TP contents of all the six layers concerned are similar and the maximum TP contents are no clear distinctions except for the sixth layer.According to the data from the previous surveys, the average TP contents of the surface layer of the bottom mud, are similar since the 80's of the 20^(th) century, however, the maximum value increases gradually based on the comparison concerned.Furthermore, the relationship between OM and TP contents is analyzed as well.
