黄河的大部份支流是多泥沙河流,治理的根本措施是尽快搞好水土保持,但从大面积来说,显著地减沙是需要较长时间的。在长时间里,贫乏的水资源如何利用?干旱贫瘠的面貌如何改变等问题始终摆在人们的面前。带着这些问题,我们调查了红柳河及新桥水库,得到了不少的教益。 Most of the tributaries of the Yellow River are sediment-laden rivers. The fundamental measure for governance is to do well in soil and water conservation as soon as possible, but for a large area, it takes a long time to reduce sediment significantly. For a long time, how to use poor water resources and how to change the arid and barren landscape have always been put in front of people. With these questions, we investigated the Hongliu River and the Xinqiao Reservoir and got a lot of lessons.
