| 摘 要： | 温榆河是北京市的主要排水河道,在比较河道生态需水量计算方法的基础上,结合温榆河河道、水资源水环境特点.选择了一种水力学方法R2-Cross法来计算生态需水量;界定了温榆河不同时期的生态目标,分时段进行了生态需水量计算;计算的温榆河生态需水量为3 985万m3/a;为温榆河流域水资源优化配置提供了科学依据.

| Abstract: | The Wenyu river is a main draining channel of Beijing.Based on comparison of the methods and combined with the characteristics of river course,water source and water environment,the R2-Cross,which is a kind of hydraulic method,was chosen to calculate the ecological water requirements of the Wenyu river.The total ecological water requirements,which were calculated according to the ecological objectives in different periods,were 3 985 m3/a.The result may provide a reference for optimal allocation of water res... |
