Abstract Hippophae rhamnoides is a kind of pioneer plant in the gully slopes in Soft Sandstone Area (SSA) for eco-economical consideration. By means of Markov model, the ratio trends of each landscape type was determined, which could support the Hippophae rhamnoides project. Separated from shrub type, Hippophae rhamnoides was listed in the landscape types together with the normal types for analysis of landscape pattern. Hippophae rhamnoides project influences the landscape pattern deeply in SSA. The prediction shows that the maximum ratio of Hippophae rhamnoides in the future should be 10.21%, and the forest percentage under 10%, which is very wise to avoid the serious death of forest including Hippophae rhamnoides in the arid climate and soil conditions. The steady ratio for open vegetation is 32.25%, which is a little larger but suitable in the area for matching the eco-environment.
