本文根据长江重庆以上干、支流水文站网观测的水文泥沙资料,初步探明三峡工程长江上游干、支流来沙特性,并分析了上游支流已建水库的拦沙作用。提出在重庆以上干、支流修建大型水库和进行有效的水土保持,减少上游来沙,以免重庆港区淤塞之害的前景。
Based on hydrological and sediment data from the dry and tributary hydrological stations over the Yangtze River in Chongqing, the characteristics of dry and tributaries to the Three Gorges Project in the upper reaches of the Three Gorges Project are analyzed. The sediments from the reservoirs of the upstream tributaries are analyzed. Put forward the prospect of building large-scale reservoirs and carrying out effective soil and water conservation in dry and tributary areas above Chongqing and reducing the infiltration in the upper reaches to avoid the blockage of Chongqing Port Area.
