Based on investigations of the hydrologic characteristics of the Shule River basin,studies of the hydro-chemical properties of the basin are mainly carried out in this paper.Most of the sections of the Shule River are dominated with HCO3- in anions and Ca2+ in cations,with orders in milligram equivalent percentage of HCO3ˉ >Cl- >SO42- in anion and Ca2+ >Mg2+>Na++K+ in cation.However,different orders occur in the lower reaches of the Danghe,namely,HCO3-> Cl-> SO42- in anion and Ca2+ >Na++K+>Mg2+ in cation.According to conventional hydro-geological methods,three types of river water,i.e.,bicarbonate,sulfate and chloride,can be classified by taking the major aqueous anions and cations milligram equivalents as criteria.Tests show that most samples belong to bicarbonate types.According to the sampling test,the total mineralization of the river water varies between 256 and 414mg/l,total hardness ranges between 3.37 and 7.16me/l,and total alkalinity,between 2.62 and 4.25me/l. This paper also studies and analyses the concentrations of the trace elements of the river water in the Shule River basin and makes an assessment of the water quality of the region.Suggestions and countermeasures on water conservation are also presented.
