Analysis of mechanism of the salinization process and the salinity variation in Bosten lake

The salinizing process of Bosten lake is attributed to the human-activities and the climatic process in the past several decades.Based on the relation between the lake's salinity and the salt budgets,a meaningful equation expressed with the factors of water volumes,slinities and evaporation etc.is studied to gain insight into the mechanism of the salinization process.With the analyses of the data from 1960 to 1999,the salt mixing ratio is introduced for evalutating the unavailable data,and the effect of each factor on the lake's salinazation is discussed quantitively.The limitations of the lake's salinity also are calculated in theory in several cases,Bosten lake,with 1.1 g/L at the rest salinity state,is a slightly salt lake rather than a fresh one.
