文章以塔里木河下游12次应急生态输水资料为背景,以塔里木河下游英苏、阿拉干、依干不及麻3个断面为例,根据实地观测得到的地下水资料,对3个断面的地下水埋深的变化、地下水矿化度和pH值等水质指标的变化进行了分析。结果表明:随着输水次数的增加,地下水埋深有抬升的趋势;地下水矿化度与输水量的多少有密切的关系,输水量越多矿化度越低,且地下水矿化度随着离河道距离的增加而增大;地下水pH值的变化与输水次数与输水量成正比。
Taking the 12 emergency ecological water conveyance data in the lower reaches of the Tarim River as an example, taking the three sections of the Lower Reaches of the Tarim River as the Ying-Su, A-Le-Gan and Yan-Gan-Hu Ma as an example, the groundwater buried in the three sections Deep changes, the degree of groundwater salinity and pH value of water quality indicators were analyzed. The results show that the groundwater depth has a tendency to increase with the increase of water transfer times. The degree of groundwater salinity is closely related to the amount of water transferred. The more the amount of water transferred, the lower the degree of salinity. The degree of groundwater salinity With the distance from the river increases; changes in groundwater pH and water delivery is proportional to the number of times.
