查干湖水量平衡差异及不明水量的探究

根据对查干湖多年水量平衡的分析,查干湖在欠水年中水位也基本保持稳定,故推测每年还有不明水量进入查干湖.经过对引松渠道基本要素、沿程井水位变动情况进行分析,采用给水度法计算出渠道沿程地表潜水进入查干湖约1.7亿m3,历史文献及现场查勘也证明了结论的合理性.

research for the Chagan lake water volume balance differences and unidentified water volume

According to the analysis for Chagan lake's water volume balance for many years,the unidentified water volume into the Lake is found because its water table is stable during the drought year.After researching to the basic elements of the channel and the water table of the wells along it,the method was used and figured out the surface water along the channel dive into the Lake which about 1.7 billion m3,the historical documents and on-site survey also proved the conclusion is reasonable.
