【摘要】 基于国内外关于河道生态需水的研究现状和研究方法,针对伊通河农村段河流丰水期流量大增、而枯水期严重缺水的特点,以维持河道水生生物栖息环境和稀释污染物为主要生态环境目标,选择Tennant法和月保证率等方法,计算了伊通河农村段生态需水量.结果表明:伊通河农村段生态基流量为1.14亿m~3,自净需水量为1.75亿m~3,河道生态需水总量为1.76亿m~3;8月生态需水量最大,为0.93亿m~3.更多还原

【Abstract】 The development of ecological water demand research provides a basis for rational allocation of water resources and the improvement of water environment.Based on the research status and research methods of the river ecological water requirement at home and abroad,this article aims at the increase of the flow in the rural section of the Yitong River,and the severe water shortage during the dry season.For example,with the main eco-environmental objectives of maintaining the habitat of aquatic life and diluting pollutants,the Tennant method and the monthly guarantee rate method were selected to calculate the ecological water requirement of the rural section of the Yitong River.The ecological base flow in the rural section of the Yitong River was 1.14×10~8 m~3,the self-purification water demand was 1.75×10~8 m~3,and the total ecological water demand of the river was 1.76×10~8 m~3.In August,the ecological water demand was the largest,being 0.93×10~8 m~3.更多还原
