摘    要:输沙量、侵蚀量与泥沙输移比的流域尺度转换研究是当前流域侵蚀产沙研究领域的前沿课题,旨在通过尺度转换理论将坡面小区试验研究成果转换到流域的更大范围。以赣江流域实测输沙量和计算侵蚀量与泥沙输移比数据为基础,探讨了该流域3个变量的流域尺度关系,进而研究分析了3个变量尺度转换的可能性。3个变量与流域面积的关系散点图和相关方程都反映了这3者与流域面积不存在明显的相关关系,相悖于前人反比关系的结论。文章还阐述了流域面积的内涵及输沙量、侵蚀量和输移比的影响因素与流域面积的关系,发现3个变量的影响因素与流域面积不存在尺度效应。由此推断在赣江流域输沙量、侵蚀量和泥沙输移比实现尺度转换存在的可能性不大。这一研究结论是否成立或是否具有普遍性意义还有待于更多流域的研究成果来进一步证实。

关 键 词:输沙量  侵蚀量  输移比  尺度转换  流域面积  赣江流域

Abstract:The research of sediment discharge, erosion amount and sediment delivery ratio is known as frontier topics in the field of soil erosion and sediment yield in a drainage basin, with the hope that the research results of slope or runoff plot could be transformed into much larger areas according to the theory of scale transformation. Based on the measured sediment discharge, calculated erosion amounts and sediment delivery ratio in the Ganjiang River Basin, this paper discusss the relationships of the three variables at a basin scale, and analyzs the possibilities of scale transformation of the three variables. Both the scatter diagrams and correlation equations of the three variables and drainage areas reflected the fact that the three variables are not correlative with the drainage area and against the conclusion that the three variables have inverse relations with the drainage area presented by some scholars. It also describs the connotation of basin area and its relationship with the influencing factors of sediment discharge, erosion amount and sediment delivery ratio. The result reveals that there is no scaling effect between the influencing factors of the three variables and basin areas. Therefore, there is little possibility for scale transformation in sediment discharge, erosion amount and sediment delivery ratio in the Ganjiang River Basin. Further research work should be done to find out if this conclusion could be reliable and have a universal meaning.
Keywords:sediment discharge  erosion amount  sediment delivery ratio  scale transformation  basin area  Ganjiang River Basin
