| 地下水补给来源及水位变化是干旱– 半干旱地区生态和植被的主要制约要素之一，也是
开展流域生态和环境治理技术与试验示范的关键。通过青海湖流域2000 年8 月和2009 年8 月浅
层地下水埋深的调查，以及地下水、河水和雨水氢氧同位素分析，揭示了青海湖流域浅层地下水

用水量的影响外，主要与降水量、地形密切相关。 |

| Abstract: |
| Inland shallow groundwater plays a key role in local drinking, irrigation and regional economic
development, especially in semi-arid and arid areas. For the Lake Qinghai catchment, the recharge and
table level of shallow groundwater are one of the most important essential factors for land ecology and
vegetation conditions and for ongoing ecologic restoration tests on wetland, deserted and grass lands.
Through an investigation of shallow groundwater table level in August 2009 and a comparison with that
in August 2000, and analyses of hydrogen and oxygen isotopic compositions of shallow groundwater,
river and rain water samples, the natural condition of isobaths of shallow groundwater table level within
the Lake Qinghai catchment was demonstrated. The data indicate that precipitation is the major recharge
source of shallow groundwater whose table levels are affected by precipitation amount and terrain,
besides consumption by local residents. |
