藤本植物开发利用价值的综合评价

Integrative evaluation on the exploitation and utilization value of vine species

根据藤本植物的生态生物学特性及其在城市园林绿化中的应用,确定了评价藤本植物开发利用价值的目标层,包括株型、叶型及叶色、攀附能力、抗逆性、资源数量、利用程度等16个标准层指标的层次分析(AHP)评价模型。应用这一模型对中国科学院华南植物园引种栽培的81种藤本植物进行开发利用价值的综合评价。结果表明,首冠藤、蔓生金虎尾、锦屏藤、山蒟、异叶爬山虎等8种藤本植物有很高的开发利用价值,心叶蔓绿绒、东南爬山虎、砾叶粉藤、粉叶羊蹄甲等24种藤本植物有较高的开发利用价值,假蒟、樟叶木防已等19种藤本植物开发利用价值低。该评价模型及分析结果将为合理开发利用藤本植物资源提供理论依据。

According to the ecological and biological characteristics of vine species and its utilization in urban landscape greening, we developed a multi-factor appraisal system that consists of 16 appraisal indices, for evaluating the exploitation and utilization value of vine species, based on the Analytic Hierarchy Process （AHP）. A total of 81 ornamental vine species that were introduced and cultivating in South China Botanical Garden, the Chinese Academy of Sciences, were evaluated for their exploitation and utilization value, using this appraisal model. The results showed that some vine species has very high exploitation and utilization value, such as Bauhinia corymbosa, Heteropterys acutifolia, Cissus sicyoide, Piper hancei, Parthenocissus heterophylla, etc.; some others has high exploitation and utilization value, such as Philodendron oxycardium, Parthenocissus austro-orientalis, Cissus rhombifolia, Bauhinia glauca, etc. and some others has very low exploitation and utilization value, such as Piper sarmentosum Cocculus laurifolius etc. This method system and the results in this study were proved to be satisfied in accuracy and very useful for exploiting and utilizing the ornamental vine resources.
