摘　　要：加强对植物耐旱能力的评估可以在规划时因地制宜、适地适树,增强城市绿地系统的生态弹性。文章在对植物的形态特征、响应机制与耐旱习性分析的基础上构建了由叶型、叶质、枝茎结构和自然生境4类23种耐旱指标组成的评价体系;通过对济南常见的104种园林木本植物的评估总结出它们的耐旱优先特征,并以此探讨了基于形态特征为主导的耐旱园林植物选择途径,为不同立地科学选择树种提供对策。The assessment of plants drought resistance can ensure the suitable species for suitable land in landscape ecosystem planning and increase the ecological resilience of urban green spaces.Based on the analysis of the morphological feature,response mechanism and drought resistance of landscaping plants,the study established an evaluation system which includes 23 drought resistance indicators under 4 categories of leaf shape,leaf texture,stem structure and natural habitat.After assessing the drought-resistant characteristics of 104 species of plants in Jinan,the authors obtained the optimized chain of drought resistance,and explored the approach to woody landscaping species selection oriented to morphological characteristics.This study provides the countermeasures for the reasonable selection of landscaping plants for different habitats.
