本刊讯截至8月20日,通过黑河流域水量统一管理和调度,黑河尾闾湖泊东居延海已连续12年不干涸,再次刷新历史记录。目前,东居延海水面面积保持在40 km~2左右,蓄水量达到5 050万m~3,周边地区生态环境得到显著改善,湖滨地区地下水位升幅明显,芦苇等水生植被面积不断扩大,植被退化区域经过灌水、抚育等人工措施的实施也已逐步恢复。多年维持一定水面面积的东居延海,初步遏制了额济纳绿洲生态恶化的趋势。
As of August 20, through the unified management and dispatch of water in the Heihe River Basin, the eastern coast of the Heihe River has not dried up for 12 consecutive years and once again set a new historical record. At present, the water area of the East Juyan Sea is maintained at about 40 km 2 and the water storage capacity reaches 50.5 million m 3. The ecological environment in the surrounding areas has been significantly improved. The groundwater level in the lakeside area has increased significantly, and the area of aquatic vegetation such as reeds has been expanding. The implementation of the artificial measures such as irrigation and tending have also been gradually restored in the degraded areas of vegetation. The East China Sea, which has maintained a certain surface for many years, initially contained the trend of ecological deterioration in Ejin Oasis.
