湖荡湿地对输水河道磷的截留净化作用
Interception and decontamination of phosphorus in input watercourse with lake wetland
摘要
Abstract
The interception and decontamination of TP , TDP, PP, and PO 3-4 and their impact factors were analyzed in Ezhen Lake and Caohu Lake , which are located in the waterway of the Wangyu River in the Taihu Basin .The main results are as follows: (1) The two lake wetlands can remove phosphorus , especially PP and PO 3-4 , from the input watercourse by interception and decontamination .(2) Factors like the area and spatial shape of the lake , the location of sites of water input and output , and the distribution of hydrophytes in wetlands affect the removal rate of phosphorus.(3) Significantly negative correlations were found between water temperature , pH, DO concentration, Chl-a concentration, and phosphorus, while the correlations between water temperature , pH, DO concentration, and Chl-a concentration were significantly positive .Therefore, algae are a key factor influencing phosphorus removal .关键词
