摘　　要：为充分挖掘川西亚高山地区观赏类植物资源优势、促进高海拔地区城市园林绿化和景观生态修复的乡土物种产业化发展,基于文献查阅和实地调查,综合考虑植物观赏价值、生态适应性价值和开发价值,确定17个评价指标,建立层次分析法(AHP)评价模型,针对该区域较为常见的50种乡土木本植物进行综合评价,根据综合评价分值将资源化利用价值由高到低划分为4个等级.结果显示:I级(>4.0)植物6种,以山光杜鹃(Rhododendron oreodoxa)为代表,观赏价值和应用价值较高,可优先作为高海拔地区园林绿化和景观植物进行开发利用;II级(3.6-4.0)植物22种,可适度作为高海拔地区园林绿化植物开发应用;III级(3.2-3.6)和IV级(<3.2)植物各11种,建议小范围区域内试种,适时评估其开发利用价值.采用AHP法筛选出的6种I级植物能准确地反映出亚高山地区木本植物的应用价值,予以重点推荐;结果可为亚高山地区生态恢复和城市园林物种的选择提供科学的参考依据.The western Sichuan subalpine region contains ornamental plant resources that promote high-altitude city landscaping,restoration of industrialized areas,and landscape ecological restoration of native species.Based on a literature review and field survey,this study considers plant ornamental value,ecological value,and development value applicability and determines 17 evaluation indexes,to establish a hierarchical analysis method(AHP)evaluation model to determine the plants that are most suitable for landscaping.A comprehensive evaluation was carried out on 50 kinds of native woody plants in the region to categorize the value of woody plant products into four grades,ranging from high to low value.The results showed that six species of Grade I plants(>4.0)with high utilization value,represented by Rhododendron Oreodoxa,had high ornamental and application value,and could be developed and utilized as landscape plants even in high-altitude areas.Twenty-two species were Grade II plants(3.6-4.0),which can be moderately developed and applied as landscape plants in high altitude areas;and 11 species were grade III(3.2-3.6)and grade IV(<3.2).We suggest planting species in a small area and evaluating their development and utilization value in due time.In conclusion,the six Grade I plants screened by the AHP method can accurately reflect the application value of woody plants in subalpine areas and can be recommended as a scientific reference for ecological restoration and selection of urban garden species in subalpine areas.
