In recent ten years,the concept of slope ecological protection has emerged and the relevant practices are booming.It is urgent to develop a new method for analyzing the stability of slope covered with vegetation because the influences of vegetation on the stability of slope have to be considered.Based on the summary of the existed researches,this paper puts forward a new method for stability analysis of sandy soil slope covered with vegetation.As the distribution principle of root in soil and the improvement of soil shearing strength caused by roots are considered in the method,the method could be put into practice in the near future.
