Abstract: 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.
