摘要: 阐述了水资源的可再生性及天然可再生能力的表示方法,探讨了水资源天然可再生能力与水资源更新速率之间的关系。研究结果显示用单位面积单位时间的可更新水资源量来表述水资源天然可再生能力具有突出的优点。研究同时表明水资源更新速率与可更新水资源量之间关系密切,如果获得了水资源更新速率,则较易获得其可更新水资源量,从而可以研究水资源的可再生性。以全国水资源一级分区及黄河流域二级分区为例评价了其水资源的天然可再生能力。

Abstract: The reproducibility and its ability of natural water resource are introduced in this paper, the relationship between reproducible ability and refresh rate of water resource is discussed. The results show that it has many advantages to use refresh water resource per area per time as reproducible ability of water resource. The relation between reproducible ability and refresh rate of water resource shows that if the refresh rate of water resource is known, it is very easily to achieve the reproducible ability of water resource. The first order water resources areas in China and the second order water resources subareas of Yellow River are taken as an example to assess the natural reproducible ability.
