【摘要】 通过分析乌梁素海表层沉积物有机质、总氮与总磷的含量,结果表明: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;在水平方向上,有机质与总氮和总磷含量显著相关,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。更多还原

【Abstract】 Through analyzing the content of organic matter,total nitrogen and total phosphorus in Surface Sediments from the Wuliangsu Lake,it shows that the organic matter 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. In horizontal direction,the organic matter content has significant correlation with the total nitrogen and total phosphorus content,demonstrating that organic matter accumulation is an important factor which promo 6 tes lake eutrophication and water eutrophication has an obvious endogenous.更多还原
