摘要
确定风、沙源、风沙流、下垫面和沙地地表形态是构成风沙运动体系的5个基本要素。确定风速的强弱、沙粒的走停、气流含沙量的盈亏、下垫面的扬抑作用和沙地地表的蚀积变化是这些基本要素各自参与风沙运动的主要表现特征。这些表现特征都能一分为二,于是10个对立侧面的相互作用构成了风沙运动发展变化的总体。系统地研究这些侧面的组合关系、揭示它们相互促进相互制约的演变机理,进而依其内在联系进行排序,将其串联成一体,并绘出图式,这样便形成了名之曰 强、弱、扬、抑、走、停、盈、亏、蚀、积十纲辩证"的风沙运动理论体系。其中 强、弱、走、停、盈、亏、蚀、积八纲辩证"是本理论体系的核心。
Wind force, sand source, eolian sand flow, underlying surface, and ground surface terrain are the five basic elements that compose the system of eolian sand movement. The major expressive characteristics of these five elements participate in eolian sand movement comprise changes between strong and weak of wind speed, go and stop of sandy particles, load and loss of sand content in air flow, rise and fall of underlying surface, and erode and accumulate of sand on land surface. Each expression characteristic can be divided into two aspects. Therefore, the interactions of ten opposite aspects make up of the total development and change of eolian sand movement. This paper deals with the combination relationships of these aspects, and reveals evolvement the mechanism of their inter-promotion and inter-restrictions, then makes ordination and plot based on the internal relations. Consequently, the theory system on eolian sand movement has been created, which is called dialectics of ten aspects, including strong, weak, rise, fall, go, stop, load, loss, erode, accumulate, in which Dialectics of eight profiles including strong, weak, go, stop, load, loss, erode and accumulate, is the core of the theory system.
