- 摘要:
- 2000年7月开始，实施了黑河下游应急生态输水工程，水流于2002年7月17日流进黑河尾闾端的东、西居延海。针对以上情况，根据2001年和2003年所采集的浅层地下水水样，进行了水化学性质分析。根据分析结果，得出分水后的主要离子变化，并分别从时空变化的角度，来说明额济纳绿洲浅层地下水水化学在分水过程中的响应。结果表明：全区的各种离子均含量在分水前后有明显变化，水的矿化度、总硬度和碱度在分水后整体上大幅度地降低，水化学变化对分水的响应程度较为明显，分水具有十分重要的意义。
- Abstract:
- Since July of 2000,the ecological water-conveyance project was carried out,and water conveyed by the project flowed into the West and East Juyanhai Lakes on July 17,2002 located at the lower end of the Heihe River.Against the situation,the water samples were collected from the shallow groundwater of Ejina oasis in 2001 and 2003 respectively.Through a chemical analysis,getting the main ions’ changes after its water import and at the same time the hydrochemistry of shallow groundwater in Ejina Oasis was greatly responded with water import with temporal and spatial variation.Results show the average content of all kinds of ions changes obviously;mineral content of water,total hardness and alkalinity fell wide-range down;the hydrochemistry changes are responded with water import.So there is significance about water import.
