摘要
笔者就北羌塘中部自然地理和地质背景概况 ,论述了区内复杂的水文地质条件和地下水类型 ,阐述了不同泉水出露状况及其水文地质特征 ,并对水样测试结果进行了详尽的地球化学分析 ,从而认为区内地下水水化学组合类型为阳离子以Na+ 为主 ,阴离子以Cl-为主的特点。
The hydrogeological conditions and groundwater types are discussed in terms of physical geography and geological background in north-central Qiangtang.The spring occur- rence and hydrogeology are outlined.The geochemical analytical results of the water samples show that the cation Na^+ and anion Cl^- are accentuated in the groundwater in the study area .
