Till the late stage of the desert, the divergent latitudes was drifted southwards due to the lond period climatic fluctuations and thus the whole desert was within the extent of the westerly winds.
The formation of the plateau created sandy substance and accelerated the formation of south-east monsoon system and other climate changes, which directly influenced the occurring of desert in geologic period, and indirectly influenced the desertification of North China in the historic period by effecting the early living pattern of man.
The A1-P and Fe-P were the second resource. The Ca10-P and Ca8-P were the phosphor depository of the Grey desert soil promoting the transform from the CalO-P and Ca8-P to the Ca2-P was the key factor pf raising the supplying phosphor capability of the Grey desert soil.

The study of the formation mechanism of aeolian landform hasn't been made new progress in recent years, and at present it is a key aspect on the research, theoretically and practically, of desert science. On the basis of field observation, many scientists in the field in various countries have proposed some hypotheses, but nowaday these hypotheses are still being under exploration and not identified by site-observations, and at the same time, its physical process is lack of clear delineation.
This paper mainly states the surface micro-structure shape of China's arenaceous quartz, which is formed under the effect of external building force as glacier, water flow ( including rivers, morning and evening tides ) and wind erosion etc. According to this, the evolution history of sandy deposites and the relationship between the shape structure of sandy material and the cause of formation can be further investigated offer grounds of argument on source of sandy material in desert.
