摘　　要：黄河流域修建了大量水库，并开展了水土保持工作，对改善流域生态环境和提高农业产出有重要作用，同时也减少了入黄泥沙，从而缓解了下游河道的淤积。研究表明，位于长城以南子午岭林区以北大约８万ｋｍ２的区域为粒径大于０．０５ｍｍ的粗颗粒泥沙主要来源区，２０多年来治理粗颗粒泥沙来源区的工作已见成效。In the Yellow River basin, reservoirs constructure and water and soil conservation measures carried out are very useful to improve ecology environment and agriculture production, to reduce sediment into the Yellow River and deposition in lower reaches channel. It is found out that the source region of coarse sediment (grain size of more than 0.05mm)with area of 80 000km 2 lies to the south of Great Wall and north of Ziwuling forest area. In recent 20 years,the controlling effects have been shown in coarse sediment source area.
