| 摘 要： | 通过 2 0 0 3年 4- 5月在黑河下游额济纳分两条路线 (a -a’和b -b’)采集水样 ,分析了额济纳现状水资源特征。远离河道区域水化学类型有HCO3·SO4-Na、Cl·SO4-Na·Ca、HCO3·Cl-Na·Ca和SO4·Cl-Na ;在河道附近或河道地区水化学类型主要是SO4·HCO3-Na ,类型单一 ;研究区矿化度和各离子含量随距离补给源的远近增减而升降 ,表明它们主要依赖于上游补给水量 ;同时 ,额济纳地处干旱区 ,降雨稀少 ,该区植被的生长发育主要依靠浅层地下水 ,地下水环境的改变直接导致了区域生态的变化。

| Abstract: | The chemical features of shallow groundwater were studied by collecting water samples in Ejina on the lower reach of Heihe river in 4, 2003, the lines of collecting samples were of two: one was a-a' and the other was b-b'. The types of groundwater included: (1) these were mainly HCO 3 SO 4-Na、Cl·SO 4-Na·Ca、HCO 3·Cl-Na·Ca and SO 4·Cl-Na away from the riverway –a-a’ section, respectively, but the HCO 3·SO 4-Na is the main type on b-b’. (2)The changes of mineralizationand content of ions accorded with the distance from suppling regions, which depended on the water quantity of upper reaches. (3) Ejina was located in arid inland area with, sparse precipitation, and dry climate, so there was a close relationship: The change of shallow groundwater environment led to the change of ecology in this region. |
