Approach of soil and water conservation on desilting highland in typical irrigation area from the Lower Yellow River

摘要

Exampled by Weishan irrigated area, the largest irrigation area in the lower basin of Yellow River, this study summarizes the experience of erosion controlling on desilting highland for years and proposes comprehensive control modes including water diversion irrigation management. After taking the engineering measures such as land leveling, soil mulching and land planishing and the vegetation measures such as slope protection by highland vegetation and shelterbelt network, the desilting highland in Weishan irrigation area was overall controlled, soil erosion and ecological environment deterioration have been restrained effectively.
