摘要
基于对秦岭山地大量的野外实地调查、访问调查和文献资料,从观赏特性、生物学特性和资源潜力3个方面选择了13个具体指标,应用层次分析法(AHP)建立了秦岭山地主要野生木本观赏植物资源的评价指标体系,应用yaahp6.0软件计算了评价体系中各指标的权重,运用综合评价法对135种野生木本观赏植物进行了评价,并根据综合评分结果划分了未来优先开发利用等级。结果表明:四照花(Dendrobenthamia japonica var.chinensis)、陕西卫矛(Euonymus schensianus)等24种植物可作为优先开发利用对象;流苏树(Chionanthus retusus)、金钟花(Forsythia viridissima)等44种植物可作为次重点开发利用对象;山矾(Symplocos sumuntia)、绣线梅(Neillia sinensis)等被48种植物可作为一般开发利用对象;梓树(Catalpa ovata)、紫柳(Salix wilsonii)等19种植物在开发利用中可较少考虑。
The analytical hierarchy process (AHP) was applied to construct the evaluation index system for the main wild woody ornamental plant resources in Qinling Mountains based on a large number of field surveys, inter view surveys in the region and literatures. The evaluation index system was built from ornamental characteristics, biological characteristics and resource potential, including thirteen specific indicators. The weights of evaluation in- dices were calculated using the software yaaph6.0. One hundred sixty three wild woody ornamental plants were e valuated by comprehensive evaluation method. Future priority development and utilization classification for these plants were determined according to the results of composite score. The results demonstrated 24 species could be used as the priority development and utilization objects, such as Dendrobenthamia japonica vat. chinensis, Euony- mus schensianus etc. 44 species could be used as sub-priority development and utilization objects, such as Chio nanthus retusus, Forsythia viridissima etc. 48 species could be used as general development and utilization ob jects, such as Symplocos surnuntia, Neillia sinensis etc. and it could pay less consideration to 19 species in future development and utilization, such as Catalpa ovata, Salix wilsonii etc.
