| 中文摘要: |
| 通过环境同位素技术和指数加权量化研究表明，黑河流域走廊平原地下水补给变异主要受区域气候变化和中游区人类活动影响；中游区人类活动对地下水补给变异影响强度达85%，春灌是关键时期。提出实现黑河流域地下水的可持续利用和下游区生态环境的有效保护，关键是规范中游区人类用水行为，使其符合黑河流域水循环自然规律；必须重视连续枯水期人类活动影响强度的科学调控，确保黑河干流的人类活动影响度低于37%。 |
| 英文摘要: |
| The variation of groundwater replenishment and its mechanism in the middle reaches of Heihe River basin, Xinjiang Autonomous Region, China, are investigated by means of environmental isotopic technology and exponential weighted averages method. It is found that the impact intensity of human activities on groundwater replenishment is 85% and the effect of irrigation in spring season is remarkable. Therefore, the key measure for realizing the sustabinable utilization of groundwater resources and protecting the ecological environment is to adjust the human activities in conformity with the principle of water cycling. The critical impact intensity of human activities in Haihe River basin is 37%。 |
