| 摘 要： | 简述国外河道生态需水计算方法,认为现阶段水文学法最适合于我国河道生态需水研究。河道生态需水与流域生态系统相辅相成,应符合水文气象的季节性特征,适应生态系统对水文条件的季节性要求。生态需水目标与流域水资源开发利用需求以及民众对生态的认识和需求有关。以年历时保证率基本不变,对流量历时保证率法的各月生态需水作修正,体现以丰补枯、水热同步,更符合流域特征,成果与常用方法和评价标准的协调性好。

| Abstract: | This paper briefly describes the calculation methods of eco-water demands in river abroad,and thinks that hydrological method is the most suitable for the research of eco-water demands in China at present.The eco-water demands is complementary to the ecosystem of river basin,which should conform to the seasonal characteristics of hydrology and meteorology and adapt to the seasonal requirements of hydrology.The goal of eco-water demands is related to the development and utilization of water resources in the river basin and people's understanding and demand for ecology.Basically unchanged the annual duration guarantee rate,revised the monthly eco-water demands of the flow-duration guarantee rate method,which is in line with the characteristics of the river basin and is coordinated with common methods and evaluation standards. |
