| 摘 要： | 以盐量平衡为基础,把影响湖水咸化的原因分解为水量、矿化度、水面蒸发等咸化因子,从物理机理上解析了各因子之间的相互关系。通过1960-1999年的逐年资料分析,提出盐分交换率概念,定量地阐明了不同时期各因子对湖水矿化度稳定性的影响。在博斯腾湖的不同情景下,推算了湖水矿化度的极限值;从理论上指出博斯腾湖属于微咸湖泊,其稳定矿化度为1.1 g/L,博斯腾湖的咸化原因可归因于人类水土开发活动和气候因素的综合影响。

| Abstract: | 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. |
