摘　　要：沙棘人工林是晋陕蒙砒砂岩区主要的退耕还林树种之一,在砒砂岩区生态环境治理中发挥着重要作用。通过理论分析、频度分析、专家咨询法构建了砒砂岩区沙棘人工林生态系统服务功能评价指标体系,应用博弈论综合赋权法将主、客观权重进行组合,得到综合权重。采用AHP—模糊综合评价、TOPSIS法、灰色关联投影法对砒砂岩区沙棘人工林生态系统服务功能进行了动态评价。结果表明:砒砂岩区沙棘人工林生态系统服务功能2010年、2007年、2004年、2001年综合评价结果分别为良好、一般、较差、较差,砒砂岩区沙棘人工林生态系统服务功能呈逐年改善的趋势,退耕还林营造沙棘人工林生态措施的实施对砒砂岩区生态环境的改善起到了积极的促进作用。Seabuckthorn plantation is one of the main plant species for returning farmland to forestland in the soft rock area in Shanxi, Shaanxi and Inner Mongolia. It plays an important role in the eco-environmental governance in the soft rock area. Through theoretical analysis, frequency statistics, expert consulting the e- cosystem service evaluation index system of seabuckthorn plantation was established. Subjective and objec- tive weights were combined to obtain the comprehensive weight by the application of Game Theory. We used the method of AHP-fuzzy comprehensive evaluation, Technique for Order Preference by Similarity to an Ideal Solution, Gray Relation Projection to evaluate the quality of seabuckthorn plantation ecosystem services in the soft rock area. The results showed that seabuckthorn plantation ecosystem services in 2010, 2007, 2004 and 2001 were good, general, relatively poor and relatively poor respectively. The quality trend of seabuck- thorn plantation ecosystem services was improving year by year. The implementation of returning farmland to seabuckthorn plantation had played a positive role in promoting the improvement of the ecological environ- ment in soft rock area.
