Distribution and Forms of Phosphorus in the Buffer Zone Sediments of Erhai Lake

Abstract:

Spatial distribution of phosphorus in the buffer zone sediments of 16 rivers around Erhai Lake was investigated in July 2013 and different rivers are classified by hierarchical cluster. The average contents of TP, IP, Ca-P and Fe/Al-P were 822.18mg/kg, 602.42mg/kg, 396.79mg/kg and 150.64mg/kg. IP is the dominant mineral form in surface sediments. The order of the average contents of TP and IP conjects to be: West>South>North, West>North>South, respectively. The spatial distribution of TP, Ca-P and Fe/Al-P in the sediments shows a significant positive correlation with that of IP. All 16 investigated rivers are divided into five types according to the hierarchical cluster analysis: Shuangyuanxi River is one type, Zhonghexi River and Mocanxi River are one type, Boluojiang River and Baihexi River are one type, Yangxi River is one type and the other rivers are one type.
