Abstract  Investigation into the effect on reducing wind under three kinds of different vegetation coverage(50%,25%,10%) in lower reaches of the Tarim River shows that their effect are respectively 49.21%, 24.44% and 9.15%. Under wind velocity of 7.7 m\5s-1, the sand transporting rate over vegetation coverage of 10% and 25% is respectively 64.44% and 8.37% of that over non-vegetation cover; Under wind velocity of 10 m\5s-1, only slight wind erosion occurred on the land with 50% vegetation coverage. Quantitatively analysis on the relationship between different vegetation coverage and reduction of wind velocity shows the effective vegetation degree of coverage. Under the common wind velocity (10~15 m\5s-1), the effective vegetation coverage should be above 50% for preventing wind erosion.
