The Damage of Heap Sediment by Dredging from Irrigated Areas to Environment in the Lower Yellow River and its Prevention
For assuring irrigation districts natural function, the sediment aggraded in the canal and depositing pool must be dredged out timely. The sediment cleared away is usually stacked on both banks of canals, and after a considerable long period of time, artificial desert came into being, as a result, the environment around irrigation districts was destroyed, and the production and living of the people and economy development there were threatened. The paper introduces the austere actuality of stacking sediment. Summarizes modes of damage caused by the stacking sediment to eco-environment, thoroughly analyzes the degree and mechanism of stacking sediment, finally put forward the measures of prevention to offer technical support to harness the harm of stacking sediment in the irrigation districts along the Lower Yellow River.
