| 摘 要： | 根据对百花湖、阿哈水库底泥分布、底泥厚度的调查情况及总氮、总磷、COD的含量测定,估算了湖库底泥和相关污染物的蓄积量。百花湖底泥平均厚度为34.3 cm,底泥干重140.9×104t。阿哈水库底泥平均厚度为45.8 cm,底泥干重84×104t。百花湖底泥中总氮、总磷、COD蓄积量分别为5400 t、1600 t、72000 t,阿哈水库底泥分别为3100 t、900 t、35900 t。并利用x射线能谱仪对底泥化学主元素进行分析。

| Abstract: | By measuring distribution and depth of sediments,the sediment deposition total nitrogen,total phosphorus and COD of Baihua Lake and Aha Lake were estimated.The results indicated the average thickness of sediment in Baihua Lake was 34.3 cm,dry weight 140.9×104 t.The average thickness of Aha Lake sediment was 45.8 cm,dry weight 84×104 t.The contents of total nitrogen,total phosphorus and COD in sediment of Baihua Lake were 54 t,1 600 t and 72 000 t.Aha Lake were 3 100 t,900 t and 35 900 t.Analysis of sediment chemical elements were used by X-ray spectrometer. |
