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、垂直分布以及磷的无机形态.表明结果:巢湖表层沉积物中的总磷含量范围在0.3～1.1 mg/g间

平均含量为0.55 mg/g.总磷含量的水平分布有由北向南递减的趋势

河口沉积物总磷的垂直分布出现变化程度的差异.巢湖沉积物无机形态的磷主要以Fe-P、Ca-P为主

两者之和为总磷的80%以上

但Fe-P与Ca-P表现出相异的空间变化特征.

Abstract

Level and vertical distributions of total content of phosphorus and phosphorus speciation in the sediments in Chaohu lake were examined and analyzed.The results showed that the content of total phosphorus in the surface sediment were ranged from 0.3 mg/g to 1.1 mg/g

and the average content was 0.55 mg/g.The trend of level distributions decreased gradually from north to south.Vertical distributions in the sediments of the river mouth existed the difference of change degree.The iron and calcium bounded phosphorus were the preponderant forms in the surface sediment

which the totals occupied above 80% of the total phosphorus.But Fe-P and Ca-P had the character of contrary space distribution.
