摘  要:
在生态需水量概念与分类的基础上,以傍黄河流域典型县域为例,采用彭曼-蒙蒂斯(Penman-Monteith)公式和基于水循环理论的方法对该地区的最小生态学需水量进行了估算。两种方法计算的最小生态需水量分别为6.097×108m3、7.018×108m3,平均值为6.56×108m3。计算结果与其它成果比较相差较小,说明该方法是合理的,可以推广应用于其它半干旱、半湿润区域,为区域水资源可持续开发利用的规划和管理提供科学依据。

摘  要:
Based on the definition and the classification of ecological water requirements,the minimum ecological water requirements in a typical county at the mid and downstream of the Yellow River are computed.In the process,the Penman-Monteith method and the method based on the theory of hydrological cycle are used.The results show that the water consumed by the eco-environment reaches 6.097×10~(8)m~(3) and 7.018×10~(8)m~(3),respectively,the average being 6.56×10~(8)m~(3).The difference between the two methods is about 13%.Comparison with other researches shows that the result is rational.The methods are reasonable and can be used in other semiarid and semi-wet regions.
