【摘要】 以巢湖为研究对象,分析研究了巢湖沉积物总磷含量的水平、垂直分布.结果表明:巢湖北部河流入湖口处沉积物中总磷含量高于其他的河流入湖口处,原因是发源于北部地区的水系带来大量的磷质,丰富了巢湖中磷的来源.柘皋河和兆河沉积物总磷的垂直分布存在变化程度的差异,主要与柘皋河补给来源于含磷地层区有关.更多还原

【Abstract】 Level and vertical distributions of total content of phosphorus in the sediments in Chaohu Lake were examined and analyzed.The results showed that the content of total phosphorus were higher in the surface sediment of mouth of lake in the north of Chaohu Lake.The reason was that a great deal of phosphorus were carried by the rivers that originate from the north of Chaohu Lake.Vertical distributions in the sediments of the river mouth are different changes in the Zhegao river and Zhaohe river.It originates that Zhegao river which flows through the phosphorus-containing layers area.更多还原
