黄河流域兰州-头道拐区间ET管理应用

黄河水权分配指标与取水管理相脱节,致使一些省份引黄耗水量超出了分水指标。ET管理能够明确区域的水循环过程与真实耗水,为区域水资源管理部门节水管理以及河道管理部门取水管理提供技术支撑。本文研究了基于ET的水资源管理模式,并将ET管理应用于黄河流域兰州-头道拐区间,具体介绍了ET管理的应用思路,并建立了区域取耗水关系,使河道管理部门取水管理具有可操作性。

ET Management Application in Lanzhou-Toudaoguai Reach of Yellow River Basin

The disjunction of water rights allocation index and water-fetching management leads to water-fetching from the Yellow River in some provinces exceed the water rights allocation index. ET management can provide regional water cycle process and real water consumption and provide technical support for water-saving management of regional water resources department and waterfetching of river department. In this paper, the water resources management mode based on ET was studied. Then ET management was applied in the region from Lanzhou to Toudaoguai in the Yellow River Basin with specific application idea. In addition, the relation between incoming flow and water consumption in the study area was built to serve for water-fetching management of river department.
