摘　　要：采用专家咨询、频度分析等方法构建了包含保育土壤、涵养水源、防风固沙等8个方面涵盖29个指标的沙棘生态服务功能评价指标体系,通过参考相关标准、参照其他植被类型的生态服务功能特征参数以及利用经验公式计算等方式进行指标体系分级,应用AHP-模糊综合评价模型对达拉特旗沙棘生态服务功能进行了综合评价。结果表明,目前达拉特旗沙棘总体生态服务功能为Ⅲ级,其中防风固沙服务功能水平为Ⅱ级,而生物多样性和景观游憩服务功能仅为Ⅳ级水平。研究发现,AHP-模糊综合评价法足适合沙棘生态服务功能评价的可行方法,具有一定的推广价值及应用性。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 seabuckthom 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 grade Ⅲ. The level of ecosystem services of sand-fixing was in grade Ⅱ, but the levels of biodiversity and landscape services were both in grade IV. Our results indicate that the AHP-fuzzy comprehensive evaluation method is practicable and feasible in studying ecosystem services of seabuekthom, and it can be widely applied in practice.
