摘要:
河成壶穴是记录流域地貌演化过程、水流与河床边界条件相互作用的关键性证据之一。以川中丘陵区两类岩性区(砂岩、泥岩)的河成壶穴为研究对象,定义壶穴形态规模与比例两类参数,对比两地壶穴形态差异性,并分析其成因。结果表明:在规模上,砂岩壶穴的密度和深度较泥岩壶穴偏大,而长、短轴则较之偏小;在平面形态上,砂岩壶穴的扁率较泥岩壶穴偏小;在垂直断面形态上,砂岩壶穴多呈倒"Ω"型、"U"型,口径深宽比偏大,泥岩壶穴多呈"V"型,口径深宽比偏小。这与两地水动力、构造、推移质、基岩与时间等因素相关,并建立壶穴概念模型。本研究将丰富与完善壶穴地貌的非地带性特征及区域代表性,为川中丘陵区河流地貌演化过程提供科学依据。
Abstract:
River potholes, proving some records of the evolution of the drainage and geomorphological，is one of the crucial evidences of the interaction between water and riverbed boundary conditions. Therefore, we take river potholes from two kinds of rock properties area (sandstone and mudstone) in Sichuan Hilly Area of China as research objects. Based on the precise measurement of the field, this paper defines scale and the proportion of pothole morphologic parameter, compares the morphological of river potholes from the two kinds of rock properties and analysis of its causes. It is showed that the density and depth of potholes from sandstone bedrock is larger than potholes from mudstone bedrock in terms of scale，on the contrary, the long and short axis of potholes is smaller. As to plane morphologic of potholes, the oblateness of potholes from sandstone bedrock is smaller than potholes from mudstone bedrock. As to vertical profiles of potholes the depth and width ratio of the potholes from sandstone bedrock is larger than potholes from mudstone bedrock and potholes from sandstone bedrock dominated by inverted Ω- and U-shape, however, potholes from mudstone bedrock dominated by V-shape. The abovementioned is closely related to hydrodynamic conditions of river, fracture,bedload, lithology and time and establish conceptual model of the potholes. This study will enrich and improve the azonal characteristics and regional representation, provide a scientific basis for the evolution of fluvial geomorphology in Sichuan Hilly Area.
