摘要: 本文讨论了四个问题。第一,黄土高原的面积为 39.1×104km2,不是 56×104或43×104km2,其中黄河中游黄土高原的面积是 31.9×104km2。第二,应将黄土高原的治理和开发紧密结合,在治理中搞开发,以开发促治理。片面地强调二者中之一,都是不正确的。第三,首先要努力防止水的流失以减少土的流失,保水的方法又主要是改土,提高土的蓄水能力。第四,1971年至1983年黄河泥沙较前减少了36%,其中水土保持的减沙量占48%,由此证明“水土保持是治黄基础”的观点是正确的。

Abstract: Four problems are discussed in this paper.(1) The area of the Loess Plateau is 39.1×104 km2 instead of 56×104km2 or 43×106 km2, in which the area of the loess plateau in the middle reaches of the Huanghe River is 31.9×104 km2.(2) The control and exploitation of the Loess Plateau should be combined closely together. The exploitation should be carried out in the course of the control, and the former pormotes the latter. It is incorrect to put undue emphasis on one of them.(3) In the first place, water loss should be avoided, so as to reduce the soil loss. The measure for water conservation is to ameliorate the soil in order to enhance the ability of water storage of soil.(4) Since 1971 the sediment load of the Huanghe River has reduced 36% in which the sedement yield reduction by water-soil conservation occupies 48%. It is thus proved that the idea of the "water-soli conservation is the basis of harnessing the Huanghe River" is correct.
