河北省野生木本植物综合评价体系的构建与应用

Establishment of comprehensive evaluation system for wild woody plants in Hebei province

树种选择是城市绿化中重要的技术要素,根据城市环境对城市绿化的要求,野生木本植物的生物学特性,确定了15个评价指标,运用层次分析法建立了河北省野生木本植物综合评价体系。并应用这一评价体系对河北省33种野生木本植物进行了评价。结果表明:盐肤木、脱皮榆、裂叶榆、茅莓、西北荀子、虎榛子6种植物在33种植物中综合评价得分较高。此评价方法将主观判断用数量形式表达和处理,较为全面准确地反映了野生木本植物开发利用的特点,对城市绿化选择野生木本植物具有一定的指导作用。

Tree species selection is a key technical element in urban virescence.According to the urban environment of the urban virescence requirements and biological characteristics of wild woody plants,15 evaluation indexes were used to establish the comprehensive evaluation system of wild woody plants in Hebei province by the Analytic pierarchy process method.33 species of wild woody plants in Hebei province were then evaluated by this evaluation system.The results showed that higher scores were observed in Rhus chinensis,Ulmus lamellosa,Ulmus laciniata,Rubus parvifolius,Cotoneaster zabelli,Ostryopsis davidiana.The subjective judgments were expressed and quantified in light of this system to fully reflect the characteristics of exploitation and utilization of wild woody plants,aiming to provide some guidance in the choice of wild woody plants during the urban greening.
