Abstract:: There exist a lot of natural seabuckthorn stands in an altitude extent from 2300 to 3600 m in the Beichuanhe basin, which is located on the upper reaches of the Yellow River.Picea crassifolia+Hippophae rhamnoides ssp.sinensis, Betula platyphylla+Hippophae rhamnoides ssp. sinensis, are two kinds of good mixed native stands for imitation of rehabilitation in high mountains of the elevation from 2700 to 3000 m, while two kinds of good artificial stands, that is, Larix principis-rupprechtii+Hippophae rhamnoides ssp. sinensis, Populus cathayana+Hippophae rhamnoides ssp. sinensis, from more than 40 years practice, are suitable to afforest in the shady and semi-shady slopes of the low mountains with an elevation under 2700 m.Pure seabuckthorn stands and mixed types of seabuckthorn forests and herbages, are eligible for high mountains and semishady and shady slopes in the low mountains.In the areas of more than 3000 m altitude, the natural seabuckthorn bushes should be mainly protected according to the concerning laws.On the process of succession, the kinds of plant species not only change from intolerant, moderate to shade-tolerant species, but the number of the species gradually decrease as the stands grow and canopy coverage increase, with the Gleason richness presenting from small to large then small again along with the growth of seabuckthorn going on, and the Simpson dominance index presenting a contrary process.The succession trends in the areas are to get to the climax community of Picea crassifolia+moss forest.The multiple eco-economic function of different seabuckthorn stands can be reached after a suitable allocation, scientific management and technology utilization based on the principle of imitating native seabuckthorn forests.
