摘要:
河流泥沙是流域水土流失与河流水文特征共同作用的结果，河流泥沙的空间分布格局和时间变化规律，可以反映水土流失时空特征及其变化过程。利用贵州省1956-2000年水文泥沙资料，分析研究了河流输沙模数的时空变化特征。结果表明：贵州省河流泥沙分布格局和时间动态变化，基本上与植被时空格局变化特征及人类活动的影响过程相吻合；河流输沙模数呈西高东低的分布格局，在时间上呈周期性变化，基本上逢3～4a就出现一个极端值，形成波峰或波谷。1965年之前的时间段内，输沙模数较小值年份出现的频率高，1965年以后则是输沙模数较大值年份出现的频率则高。1966-1967年枯水和低输沙量、1971-1972年的平水和高输沙量现象的出现，对进一步研究分析贵州省径流泥沙关系和水土流失演变过程具有重要的指示意义。
Abstract:
The river sediment results from the reaction between soil erosion and hydrological characteristics.Its spatial distribution pattern and time change regulation can reflect temporal and spatial progress of the watershed soil erosion.This article use the data of hydrology and sediment in Guizhou province to analyze sediment transport modulus.The results show that the river sediment distribution pattern and time change are almost consistent with vegetation variation characteristics and human activities.The sediment transport modulus distribution shows a tendency of higher in the west and lower in the east,and appears a periodic change per 3 or 4 years in basically.Before 1965,the smaller modulus value often occurs,but the situation was opposite after that year.There are significant for further analysis and research on the relationship between runoff and sediment and soil erosion evolution process by the case of lower water and transport sediment amount in 1966,1967 and normal flow and higher transport sediment in 1971,1972.
