摘要
通过计算 50～ 90年代洞庭湖的一日调蓄量 ,分析了其年内和不同年代间的调蓄量的变化及湖区泥沙淤积、人为围垦和城陵矶以下河段泥沙淤积对调蓄量变化的影响。得到了下游泥沙淤积是 50～
Based on the calculation results of the flood storage capacity in Dongting Lake from 1950's to 90's, the impact of sediment deposition in Dongting Lake and the reach from Chenglingji to Hankou and land use in the lake region on the flood storage capacity is analyzed. The study shows that sediment deposition in downstream reach is the main reason of flood storage increment under the same inflow condition.
