摘要
生态需水量分为河道内和河道外两部分。根据北方山区的特点,以承德市滦河流域为例,采用合理的计算方法,对承德市滦河流域生态需水量进行了估算。最后,对计算结果进行了分析和评价,并对如何保证生态需水量提出建议。
Ecological water demand is quantified into two parts of outside the river channel and inside the river channel.Based on the characteristics of the northern mountains of china,taking Luanhe River of Chengde City as an example,using a reasonable method of calculation,the ecological water demand of it was estimated.Finally,the results were analyzed and evaluated,and how to ensure the ecological water requirement to some certain recommendations were made on how to ensure the ecological water requirement.
