摘　　要：以超旱生灌木沙冬青在园林应用中的植物景观价值为研究对象,从植物的观赏特征、资源潜力、生态适应、抗逆性、其他价值等主要的制约因素入手,利用层次分析法(AHP)构建植物景观价值评价综合模型,并运用模型对沙冬青在园林应用中的植物景观价值进行综合评价。结果表明:标准层23个因素中观果价值(0.4528)、再生能力(0.3923)、适应环境(0.3764)、耐沙埋性(0.2429)、水土保持(0.2858)等指标的权重较大,分别对沙冬青观赏价值、资源潜力、生态适应、抗逆性和其他价值等约束层的影响较为显著;约束层权重最大的是抗逆性(0.3926),随后依次是生态适应(0.3039)、资源潜力(0.1472)和观赏价值(0.0929),其他价值(0.0635)的权重最小;从总权重可以看出,适应环境(0.1143)、分布范围(0.0916)、耐沙埋性(0.0856)这3个指标的排位比较靠前。To comprehensively evaluate the landscape value of a super xerophytic shrub Ammopiptanthus mongolicus in garden application,this study,based on the main restrictive factors including ornamental characteristics,resource potential,ecological adaptability,stress resistance and other values,has constructed a comprehensive evaluation model of plant landscape value using the analytic hierarchy process(AHP).The results showed that among 23 factors of the criterion layer,fruit ornamental value(0.4528),regenerative capacity(0.3923),environmental adaptability(0.3764),tolerance to sand burial(0.2429),water and soil conservation(0.2858)had greater weights with significant impact on the constraint layer consisting of ornamental value,resource potential,ecological adaptability,stress resistance and other values of Ammopiptanthus mongolicus.Among indicators of the constraint layer,stress resistance had the greatest weight(0.3926),followed by ecological adaptability(0.3039),resource potential(0.1472),and ornamental value(0.0929),while the weight of other values was the lowest(0.0635);seen from the total weight,the three indicators,namely,environment adaptability(0.1143),distribution range(0.0916)and resistance to sand burial(0.0856)ranked ahead.
