黄河冲积扇南翼上部控制区土地分异机制与土地结构

Mechanism of Land Differentiation and Land Types Composition in the South of the Upper Part of Yellow River Alluvial Fan

从地理过程分析的角度 ,讨论了黄河大冲积扇南翼上部控制区土地分异各有关因素的影响机制 ,指出黄河活动及其后期影响是这一地区土地分异的最根本的主导因素。并进一步说明了该区域土地分异表现出的逐级深化的显著规律性以及各有关类型的“梳状”

Based on researching geographical process of Yellow River alluvial fan, this paper analysies the mechanism of interaction among factors cansing land differential in the south of upper part of Yellow River alluvial fan, points out that Yellow River alluviation is the most important one in all factors, and further expounds the characteristic of land multiscale differentiation and it's types arranging in “Comb Shape” in this region.
