昆明市园林植物资源综合评价研究

对昆明市主要公园、道路等的园林植物进行调查,昆明市园林植物共有100科123属302种。采用特尔菲法确定园林植物综合评价指标体系对物种进行了综合评价与分级,结果表明,综合评价Ⅰ级61种,Ⅱ级103种,Ⅲ级105种,Ⅳ级33种,分别占总种数的20.20%、34.12%、34.76%和10.92%。耐寒性对园林植物综合等级起着决定作用;乡土树种的综合指数较高;综合指数较高的园林植物主要集中在广布、泛热带和东亚及北美间断分布的科。

Comprehensive Evaluation of Landscape Plants Resource in Kunming City

Investigation on landscape plants of major parks and roads concluded that,there are 100 families,123 genera and 302 species of landscape plants in the Kunming city. Using Delphi method,comprehensive evaluation system of landscape plants has been determined and used for comprehensive evaluation and classification of landscape plants species. Results showed that there are 61 levelⅠ species,103 levelⅡ species,105 level Ⅲ species and 33 level Ⅳ species,which accounted for 20. 20%,34. 12%,34. 76% and 34. 12% of the total tree species respectively. Cold tolerance of plants plays a decisive role in comprehensive grading; Comprehensive index of native tree species is higher; and higher comprehensive index landscape plants mainly belongs to families discontinuously distributed in the pan tropical,East Asia and North America.
