Abstract: Naiman Section of Jing-Tong railwary, with abundant sandy deposits on both sides and suffer-ring from spring drought, frequent and strong winds, is in an unique ecological condition. It has been proved that a comprehensively protective system which consists of vegetation stabilization and mechanical sandbreak is a successful measure against sand harms to railway. However, the priority is given to the vegetation stabilization and formed into a fixation-block-afforestation-enclosing system comprising of trees, shrubs and grass. During the succeeding 5 to 10 years this protective system would form a better artificial vegetation belt, thus making shifting sand fixed and ensuring smooth traffic of railway.
