| 摘 要： | pH change，distribution of anions，metals and complexing capacity in riverwater along Le An River were studied during June，1987 to November，1989．A high so24concentration was found in whole river．particularly at Gukou．High metal concentrations were found in upstream of the river，Cu．Fe，Ni and Co mainly from Dexing Copper M ine；Cd and Pb from Jishui River．Heavy water quality pollution occurred in the river section from Gukou to Daicun in Dexing Mine A rea．Complexing capacity of Le An River was low as concentration organic ligands and a high metal concentration．
