Affected by geography and local climate in the west part of Jilin Province,a large quantity of aeolian sandy soil was formed.And in the windy spring,plowing and sowing was affected seriously due to sand blown by wind.In the long term,a great deal manpower,material resources and financial resources were devoted to windbreak and sand-fixation.In order to checking up the practical effect of windbreak and sand-fixation in the several decades,we use aerial image of different period（1959 and 1978） to investigate sandy soil dynamic trend for finding out if the deep desertification was formed,and which laid the good foundation for agricultural environment plan and construction in Jilin Province.
