塔里木河流域阿拉尔生态监测站地下水动态的监测与分析

塔里木河流域由于受气候变暖和人类活动的影响,流域内生态系统已呈现出一定程度的退化迹象,为掌握其退化的迹象和程度,对2005年阿拉尔生态监测站9眼地下水常观监测井的年内地下水水位及地下水水质监测结果进行了分析,结果显示,监测区地下水位由于受农业灌溉及距塔里木河远近的影响,地下水补排关系呈现出季节性互补关系,而地下水水质的变化则反映出地下水积盐或排盐的变化过程。这表明,塔里木河既是流域灌区地下水的补给区,也是地下水径流的排泄区。

Underground Water Monitoring and Analysis on Tarim River Basin

Tarim River Basin due to warm climate and the impact of human activities,the ecosystem has shown signs of a certain degree of degradation.In this paper,in 2005 Alar Ecological Monitoring to nine underground water monitoring wells in the very concept of underground water and underground water year quality monitoring results were analyzed.Due to agricultural irrigation and underground water monitoring area from far and near the Tarim River,underground water recharge and discharge show seasonal complementary relationship.The water quality of underground water and the changes reflect the changes in salt.Tarim Basin Irrigation District is the underground water recharge and discharge zone.Through long-term monitoring of underground water,we may find its long-term trend.Thus strengthening the comprehensive underground water monitoring to monitor the dynamic changes is very important.
