The objection is to provide the theoretical base and scientific methods to control blown sand hazard and improve the eco-environment in the coastal area of Southern China, the field determination about the sand and wind movement was made, based on summary of the research fruits of predecessors. three line transect which were parallel to the main wind direction were laid according to the different underlying surface types, the line transect started from the grand calorie climax, followed by 0m, 5m, 10m, 20m, 40m and 80m, six different sample points, with experiments outdoors and investigation as main method, combining with the analysis of the data of dusty wind weather, studies the whole system composed of blown sand moving process mainly with parallel movement and particle falling process mainly with vertical movement.
