| 摘 要： | 通过对黄河流域一些主要站点近几十年来的水质、水文数据的分析研究，从灌溉农业的发展和水库修建等方面探讨了这些人类活动对黄河水量和水质的影响。分析认为，农业用水量的急剧上升是导致下游水量减少和断流的重要原因，同时也是黄河水总离子浓度上升的重要原因；水库的修建也加剧了黄河水质的“浓化趋势”。因此推行节水农业，加强对黄河流域水资源的管理是十分必要的。

| Abstract: | Discharged shortage, river desiccation and deterioration of water quality in the lower reach of the Yellow River during the latest 30 years have been receiving widespread concern. This paper analyzed the data obtained from some main monitoring stations during the last decades, discussed the impacts of irrigation and reservoir construction on the quantity and quality of the Yellow River water, and pointed out that these human activities contribute a lot to the discharge shortage or river desiccation and the increasing of the total ion content of the river water. We conclude that it is an urgent action to tailor a strategy for saving water and strengthen the water management in the Yellow River Basin. |
