新中国建立以来,开展了大规模的水土保持工作,取得了很大的成绩。水土保持在治理黄河、减少入黄泥沙方面,发挥了明显作用。各地进行的小流域治理,减少泥沙效益显著,诚少水量流失亦很明显。这样,实践就向我们提出一个非常重要的问题,即大面积种树种草和修建水土保持工程,对较大流域的水资源将发生什么样的影响呢?本文拟对这一问题进行初步分析,并期望有关专家能够对此问题作进一步的探讨。
Since the founding of New China, great efforts have been made in soil and water conservation and great achievements have been made. Soil and water conservation has played a significant role in harnessing the Yellow River and reducing sediment into the Yellow River. Small watershed management carried out in various places has obvious benefits of reducing sediment yield and obvious loss of water with little sincerity and little water. In this way, practice puts forward to us a very important question, that is, what kind of impact will happen to the water resources of the larger river basins in the large-scale planting of tree species and construction of soil and water conservation projects? This paper intends to conduct a preliminary analysis of this issue And expect the relevant experts to further explore this issue.
