黄土丘陵区的水土保持工作,去年跟着农业化高潮得到很大的发展,梯田和淤地坝占着重要的地位。淤地坝这个措拖对于稳定小型于沟的侵蚀基点,缩短沟谷崖坡从而稳定陡坡滑塌,保证坡面农林措施顺利发展既有极其重要的意义;而且还是“沟壑川台化”开拓新农田,发展农业生产的广泛手段。但这种工作虽然比较简单,也很易破坏。因为即使在较缓的坡地上修了周密的梯田埂,单只陡坡下山的洪水集中到沟里,也还是相当猛烈的。所以影响到淤地坝安全最关紧要的坝基清理,在门泛施工的群众运动中特别值得注意。兹将我们以往总结下来的点滴经验介绍出来, Soil and water conservation work in the loess hilly region has greatly developed last year following the process of agricultural climax. Terraced fields and dam sites have played an important role. This measure of siltation dam is very important for stabilizing the erosion base of small ditch, shortening the ditch valley slope and stabilizing the steep slope, and ensuring the smooth development of the slope agro-forestry measures. It is also of great significance to open up new farmland , A broad means of developing agricultural production. However, this kind of work is relatively easy to destroy. For even a well-drained terraced paddy on a sloping slope, the floods of a single steep downhill were concentrated in the ditch, still quite violent. Therefore, the dam foundation cleaning that affects the safety of the silt dam is of particular note. I will summarize the past bit by bit experience introduced,
