The evaluation index system of seabuckthorn ecosystem services in the soft rock region was constructed by expert advices, frequency analysis and so on.We summarized eight main kinds of evaluation systems which covered 29 indexes,and conducted the indexes classification referring to relevant standards,other vegetation characteristic parameters of ecosystem services,empirical formulas and other methods.Besides,we comprehensively evaluated the ecosystem services of seabuckthorn in the Dalad Banner using analytic hierarchy processing method(AHP)-fuzzy model.The results showed that the overall level of ecosystem services of seabuckthorn was in gradeⅢ.The level of ecosystem services of sand-fixing was in gradeⅡ,but the levels of biodiversity and landscape services were both in gradeⅣ.Our results indicate that the AHP-fuzzy comprehensive evaluation method is practicable and feasible in studying ecosystem services of seabuckthorn,and it can be widely applied in practice.
