| 中文摘要: |
| 利用化学分析和地统计学法，分析了研究区地下水以及土壤盐分含量、离子组成特征及其分布规律。结果显示：地下水矿化度平均值为2.37 g/L，pH值平均值为7.63，地下水中各阴离子含量由高到低依次为Cl-＞SO42-＞HCO3-＞CO32-，阳离子含量由高到低依次为Ca2+＞Na+＞Mg2+＞K+，地下水属于Cl--Ca2+型水；各层土壤pH值表现出随土壤盐分增加逐渐增加的趋势，土壤盐分垂直分布呈现较明显的表聚性；在空间尺度上，各层土壤与地下水盐分含量呈现了从研究区边缘向研究区中心增加的趋势。 |

| Salinity of soil and groundwater, main ions components and their distribution in the study area were analyzed. The results showed that: The average value of groundwater salinity was 2.37 g/L, and the average pH value was 7.63. The abandance of anions in groundwater was in the following order: Cl-＞SO42-＞HCO3-＞CO32-, while the abandance of cations in groundwater was in the following order: Ca2+＞Na+＞Mg2+＞K+, and the chemical type of groundwater belonged to Cl--Ca2+ type of water. The pH value of each soil layer increased gradually with the increase of soil salinity, and the soil salinity was accumulated at the soil surface. In the sp
atial scale, the salinity of each soil layer and groundwater was increased from the marginal parts to central parts of the study area. |
