新疆南疆地区河流泥沙推悬比分析研究

Analysis on suspended and bed-load ratio of river sediment for South Xinjiang

通过对新疆南疆地区各河流水文站大量实测悬移质泥沙资料及水力条件进行统计分析计算,运用目前常用的梅叶—彼德和R.摩勒公式、沙莫夫公式、长江科学院推移质输沙率经验曲线法进行了推移质输沙率计算。分析研究其推悬比的区域特性,从而提出了新疆南疆地区河流泥沙推悬比的初步取值范围,并分析出新疆南疆地区典型河流推悬比与目前国内推悬比研究成果相对偏小的原因。此结论为河流泥沙推悬比的进一步研究奠定更坚实的基础。

Based on the statistic analysis and calculation on large amount of the measured data of the suspended load and the hydraulic conditions from the hydrological stations on all the rivers within the South Xinjiang area,the bed-load sediment discharge rate is calculated with the normal Meyer-Peter and R.Mollet formula,Sharmov formula formula and the empirical curve of the bed-load sediment discharge rate from Yangtze River Science Academy.The regional characteristics of the suspended and bed-load ratio of river...
