摘    要:通过分析乌梁素海表层沉积物12个沉积物采样点,得出泥样中的有机质含量在10.241 g?kg-1~33.911 g?kg-1之间,均值为20.928 g?kg-1,位于湖泊北部表层沉积物有机质含量较南部高,且表现出沿岸带较丰富的空间分布特征;表层沉积物总氮的含量0.519~1.510 g?kg-1为,平均值为0.86 g?kg-1。总磷含量为0.505~0.635 g?kg-1,平均值为0.546 g?kg-1;在水平方向上,有机质与总氮和总磷含量显著相关,相关系数分别为0.814,0.738。表明有机质富集应是促进湖泊富营养化的重要因素,水体富营养化具有显著的内源性。

关 键 词:乌梁素海、沉积物、有机质、富营养化

Abstract:Through analyzing the 12 sediment sampling sites in Surface Sediments from the Wuliangsu Lake, it shows that the content of organic matter from 10.241 g•kg-1 to 33.911 g•kg-1 , its mean value is 20.928 g•kg-1 and the content in surface sediments from the north of Wuliangsu Lake is higher than the south, and has a spatial distribution characteristics of abundant organic matter content in the littoral zone of the Lake. The total nitrogen and average values content are 0.519~1.510 g•kg-1 and 0.86 g•kg-1 respectively; The total phosphorus and average values content are 0.505~0.635g•kg-1 and 0.546 g•kg-1 respectively; In horizontal direction, the organic matter content has significant correlation with the total nitrogen and total phosphorus content, which is 0.814 and 0.738 respectively ,demonstrating that organic matter accumulation is an important factor which promotes lake eutrophication and water eutrophication has an obvious endogenous.
Keywords:wuliangsuhai lake  Sediment  Organic Matter  Eutrophication
