| 摘 要： | 以洱海全湖范围内的7条采样样线及上游3个主要湖泊的底泥为研究对象,测定了总氮、总磷2个参数,分析洱海沉积物的氮磷含量及其分布特性和影响因素。实验结果表明：洱海7条样线底泥中总磷的平均值达到266.80 mg/kg,极大值为818.20 mg/kg;总氮含量的平均值达到513.60 mg/kg,极大值为1 975.40 mg/kg。洱海上游3个主要湖泊底泥总氮、总磷含量实验测定结果为总氮的平均值为370.00 mg/kg,极大值为1 397.20 mg/kg;总磷的平均值为52.43 mg/kg,极大值为140.20 mg/kg。总氮、总磷含量与辐射乡镇的人口数量及耕地面积呈正相关,总氮含量还与年人均收入呈正相关。

| Abstract: | Taking the 7 sampling lines of Erhai lake and the sediment of upper three primary lakes as the research object, the sediment about total phosphorus （TP） and total nitrogen （TN） has been tested, in order to analyze the TP and TN content of sediment in Erhai lake, distribution characteristics and influence factors. The result indicates that the seven sampling lines of TP average content reaches 266.80 mg / kg, maximum 818.20 mg / kg;the TN average content reaches 513.60 mg / kg, maximum 1 975.40 mg / kg. The TN and TP average content of sediment in upper three primary lake is 370.00 mg/kg;maximum content is 1 397.20 mg/kg;the TN average value is 52.43 mg/kg;the maximum is 140.20 mg/kg. TP and YN content is positive correlation with population and farmland area;TN content is also positive correlation with the annual per-capita income. |
