Abstract:

The study investigated the phosphorus retention effects of cascade reservoirs of Maotiao River in summer,which had been entirely exploited by 1960s.In order to find out the rules of phosphorus' retention effects,the water samples in the front of the dams by layers and outflow water of each reservoir were collected in cascade reservoirs in Maotiao River from July to September,2007.The total phosphorus and dissolved PO4P were analyzed in the laboratory.Results showed that the changes of total phosphorus are similar to dissolved PO4P in each reservoir,while the concentrations of dissolved PO4P and total phosphorus in release water were higher than that of their surface water.The concentrations of phosphorus in Hongfeng and Baihua reservoirs were higher than the other reservoirs，the P concentration was gradually reduced from upstream to downstream.Meanwhile,this characteristic was similar to the index of eutrophication.As Maotiao River's concerned,the exploitation of cascade reservoirs do have a certain retention effects on phosphorus.
