| 摘 要： | 提出了西北内陆干旱区水资源合理配置的模式与计算方法。针对生态环境脆弱的干旱区水资源利用特点,基于水资源二元演化理论与方法,保持水土平衡、水量平衡和水盐平衡,以空间配置、时间配置、用水配置、水源配置、管理配置为基本模式;从实际情况出发,以水定发展指标,提高水土资源的匹配效率,以流域为单元合理安排生态环境用水与经济发展用水,在此基础上建立了干旱区水资源合理配置模型。定量计算表明:其809亿m3的径流性水资源中,直接留给天然生态的水量有302亿m3,加上126亿m3回归水的间接支持,可供生态系统消耗的水资源达428亿m3,相对于385亿m3的现状生态需水,除黑河和石羊河流域外,生态系统的需水基本上能得到满足。

| Abstract: | In accordance with the characteristics of water resources utilization in arid zone where a fragile ecological system exitsts and on the basis of theory and method of dual water resources evolution,a mode and calcuation method of rational water resources allocation for the inland arid zone in the Northwest China is formulated,which can maintain the water-land eguilibrium,the water quantiy bulance and the water-salt equilibrium,consider the allocation in space,time,uses,water sources and management,determines the development index by available water resources on the basis of actual situation,and rationally allocate water resources to ecological use and economical use in the unit of a rever basin.The quantitative calculation indicates that among the runoff water resources of 809×108 m3,the water quantity directly allocated to the natural ecological system is 302×108 m3.Plus the returning water of 126×108 m3,the quantity of water which can supply the ecological system amounts to 428×108 m3,and the actual ecological water demand is 385×108 m3,so the water demand of the ecological system can be satisfied on the whole except the Heihe river basin and the Shiyanghe river basin. |
