| 摘 要： | 根据塔里木河下游2000-2006年11次间歇性输水影响下沿输水河道两侧地下水埋深、地下水化学组分变化的资料，结合有关输水的基本资料和土壤盐分含量变化的适时监测数据，分析了地下水化学特征的变化及影响其变化的各相关因子，结果表明：地下水化学特征的变化呈现明显的阶段性规律，地下水化学组分的变化与距离输水河道的远近、地下水埋深、河道径流量以及土壤盐分含量之间具有较高的相关性；地下水埋深在5m及5m以下时，地下水化学组分含量较低，水质较好。而埋深在5m时的水位条件能够满足该区域建群种植物的生存，为输水条件下的理想水位；地下水化学特征变化的阶段性特点和土壤剖面盐分含量的分布规律及其相互关系说明，在当前输水模式下配合面上输水将能更好地促进生态恢复。 |

| Abstract: | Based on the data of the groundwater buried depths,the chemical properties,salinity in soil profile and the basic information on each delivery of water collected from the year 2000 to 2006,the variational characteristics of groundwater chemistry and related factors were studied. The results confirmed the three stages of the variations in groundwater chemistry influenced by the intermittent water deliveries. The factors which had close relationships with the variations in groundwater chemistry included the distances of monitoring wells from water channel,the depths of groundwater,water flux in watercourse and the salinities in soils. The relationships between chemical variations and groundwater depths indicated that the water quality was the best with the groundwater ranging from 5 to 6 m. In addition,the constructive species in the study area can survive well with the depth of groundwater varying from 5 to 6 m,so the rational depth of groundwater in the lower Tarim River should be 5-6 m. |
