风水交互作用是干旱区(广义)最为广泛的一种地表现象与地貌过程。通过对西部的克里雅河、中部的毛布拉孔兑河和东部的西拉木伦河三个典型流域的实地考察、地形测量、取样,分析其地表沉积物样品的粒度、化学风化过程以及动力因素,发现:自西向东三流域的粒度特征表现为粒度变粗,分选性变差,峰态变宽,粒度的水成特性更加明显;三流域的矿物及元素风化指数表明了三流域处于化学风化的最初阶段,且自西向东三流域化学风化程度增强,物理风化程度减弱;其中,化学成分变异指数(ICV)与碳酸钙化学参数含量可以很好的区分三流域地表物质的风化特征异质性。究其原因,在流域尺度上,气候引起风和水两种营力对地表沉积物的差异性分选,使得三流域地表沉积物理化特征呈现地带性规律。
Fengshui Interactions are the most extensive surface phenomena and topographic processes in arid areas (broadly defined). Through the field investigation, topographic survey and sampling of the three typical basins in the Kiliya River in the west, the Mabulongkai River in the middle and the western Sillamulon in the east, the grain size, chemical weathering and dynamics of surface sediment samples were analyzed It is found that the grain size of the three basins from west to east is characterized by coarse grain size, poorly sorted and widened kurtosis and more obvious water features of grain size. The mineral and element weathering index of the three basins shows that the three basins are in In the initial stage of chemical weathering, the degree of chemical weathering is weakened from the west to the east, and the degree of physical weathering is weakened. The chemical composition variation index (ICV) and the content of calcium carbonate chemical parameters can well distinguish the weathering characteristics of the surface water in the three basins Qualitative. The reason is that on the scale of the basin, the climate causes the wind and water two campuses to differentiate the sediments on the surface so that the physical and chemical characteristics of the surface sediments in the three basins present the zonal law.
