中文摘要：
2009年7月对乌梁素海主体湖区的10个点的底泥进行取样，通过分析底泥沉积物TP在表层、水平方向、垂直方向的分布特点，再与TP的影响因素结合进行分析，结果表明：乌梁素海总磷的沉积受多种因素的影响，但水动力条件是影响TP沉积的最显著的因素；袁层沉积物TP在P9、P11、Q8点所在的区域出现峰值高达2．669mg／g；乌梁素海总磷的垂向分布变化较为复杂，但垂向上的峰值都在0～15cm的范围内，深度超过15cm以后总磷的含量波动很小基本不变。
英文摘要：
Ten sampling points for sediment was taken on the main Lake Wuliangsuhai in July 2009. By analying total phosphorus＇s eharacteristie in surface sediment, horizontal direction and vertical direction, we can analysis with the combination of the factors which influced total phosphorus. To the conclusion, total phosphorus deposition was affected by many factors in Lake Wuliangsuhai, However, the hydrodynamic eonsition is the most significant factor. The peek value of phosphorus was up to 2. 669 mg/g on the region of P9, P11, Q8 points. The changs of total phosphorus in vertical distribution was more complicated, but the peck in the vertical direction was in the rang of 0-15 cm. And the content of total phosphorus was basically unchanged in the depth of more than 15 cm.
