当前黄河中游地区以小流域为单元进行水土保持工作是符合水土流失自然规律的,现在的问题是如何将社会经济规律和自然规律结合起来,以期能把水土保持工作更提高一步。为此,作们曾提出在“黄河流域严重水土流失区小流域应成为农林牧全面发展的经济单元”的论点,此后又提出“黄河中游小流域治理——水土沙合理利用科学研究意见”,以期能实地试行、检验和逐步完善,同时认为在开始把小流域作为经济单元进行 At present, the work of soil and water conservation based on the small watershed in the middle reaches of the Yellow River is in line with the natural laws of soil and water loss. The question now is how to combine the social and economic laws with the laws of nature in order to take soil and water conservation work one step ahead. To this end, they have put forward the argument that “a small watershed in the serious soil erosion area of ​​the Yellow River Basin should become an economic unit for the all-round development of agriculture, forestry, animal husbandry,” and later put forward the “Scientific Research Opinions on Small Watershed Management in the Middle Yellow River Basin - Rational Use of Soil, Water and Sediment” With a view to field trial, testing and gradual improvement, at the same time that the beginning of the watershed as an economic unit
