摘要:
为了定量评价十大孔兑地区淤地坝的减沙效益,基于历史资料整理与实地详查,统计了十大孔兑地区1986年以来现存淤地坝的数量和分布特征; 采用淤积体概化法,确定了影响淤地坝减沙量的主要参数,并计算了研究区354座淤地坝的减沙量。结果表明:十大孔兑354座淤地坝累计减沙3.205 61×107t,其中减沙量最大的孔兑为西柳沟,达1.239 76×107t; 通过分析不同时段淤地坝的减沙特征表明,1986—1999年、2000—2009年和2010—2018年3个时段的淤地坝减沙量分别为4.946 6×106t,1.155 57×107t,1.555 38×107t。十大孔兑地区淤地坝具有显著的减沙作用,具有很高的减沙指标(达5 720.33～58 141.81 t/座),2000年以后的两个时间段内,随着坡面林草措施的增加,淤地坝减沙量增加,表明在这一地区,淤地坝仍然是最有效的水土保持措施之一。
Abstract:
In order to quantitatively evaluate the sediment reduction benefits of the Yudi dams in the Ten Tributaries area, and according to the historical datasets collection and detailed field investigation, we counted the number and distribution characteristics of existing check dams in the Ten Tributaries since 1986, the generalization method was conducted to determine the main parameters affecting the sediment retention, a total of 354 check dams in the study area were surveyed. The results showed that the 354 check dams in the Ten Tributaries had trapped a total of 32.056 1 million tons of sediments; the largest amount of sediment reduction in the Xiliugou was observed, which reached up to 12.397 6 million tons; the results of the sediment reduction characteristics of the check dams in different periods showed that the amounts of sediment reduction were 4.946 6×106 tons, 1.155 57×107 tons, and 1.555 38×107 tons in 1986—1999, 2000—2009, and 2010—2018, respectively. The check dams in the Ten Tributaries area had significant sediment reduction effects,which had high sediment reduction index(5 720.33～58 141.81 tons per check dam). After 2000, the sediment reduction of the check dams still increased with the increase of forest and grass measures on the slope, suggesting that the check dams is the one of the most effective soil and water conservation measures in the Ten Tributaries area.
