    Formation mechanism of interior drainage areas and closed drainage areas of the Ordos Plateau in the middle reaches of the Yellow River based on an analysis of the water cycle

    • 摘要: 在分析鄂尔多斯高原地表水、地下水与黄河流域水资源转化关系的基础上,依据地下水流系统的理论与方法,对内流区与闭流区的形成机理进行了研究,对内流区与闭流区的分布范围进行了重新界定。结果表明,在鄂尔多斯高原可划分为2个内流区和4个闭流区:内流区内虽然地表水与黄河及其支流无直接的水力联系,但地下水与黄河及其支流存在着密切的水力联系,应将其划入黄河流域;闭流区内无论地表水还是地下水,与黄河及其支流均无水力联系,不属于黄河流域;闭流区总面积为32451.4km2,与1977年《黄河流域特征值资料》中划分的闭流区面积(42296km2)相比减少了9844.6 km2,即黄河流域集水面积在原来的基础上应增加9844.6 km2。

       

      Abstract: Based on an analysis of the transformation between surface waters and groundwater on the Ordos Plateau and water resources in the Yellow drainage region and according the theory and method of the groundwater flow system, the formation mechanism of the interior drainage areas and closed drainage areas were studied and the distribution of the interior drainage areas and closed drainage areas was re-delineated. The results show that there are 2 interior drainage areas and 4 closed drainage areas on the Ordos Plateau. Although within the interior drainage areas there is no direct hydraulic connection between the surface water and the Yellow River and its tributaries, groundwater has close connection with the Yellow River and its tributaries; the interior water systems should be ascribed to the Yellow River drainage basin. Within the closed drainage areas neither surface nor groundwater has hydraulic connection with the Yellow River and its tributaries; so the closed drainage areas do not belong to the Yellow River drainage basin. The total area of the closed drainage areas is 32451.4 km2, decreasing by 9844.6 km2 as compared with that (42296 km2) given by the book The Data of Characteristic Values in the Reaches of the Yellow River” compiled in 1977, i.e.: the catchment area of the Yellow River should increases by 9844.6 km2.
