摘要:
通过对上海近30年的气候因子汇总分析,结合对上 海世博公园主要绿化树种生长状况调查和年度生物量计算,通 过典型相关性分析发现,极端高低温、强风和暴雨等5个气候 因子对树木的生长产生了不同程度的影响,有些因子严重阻碍 了树木的正常生长,成为障碍因子。经过10年的绿化实践验 证,上海世博公园对骨干树种的选择,以乡土树种为主,群落 结构较为稳定,且气候障碍因子对乡土树种的影响较小。在引 种外来树种时,采用气候相似植物区系法,结合植物耐寒、耐 热带图,把种源地划分为2个气候带和3个植物区系,并确定了 最南引种线,成功引种了红花槭等20种观花色叶乔木树种。

Abstract:
Based on the analysis of the climate factors in the past 30 years in Shanghai, combined with the investigation of the biomass of the main tree species in Shanghai World Expo Park, and their performance under the extreme climate factors, it was confirmed that the 5 climate factors, such as extreme high and low temperature, strong wind and rainstorm, made influences on the normal growth of greening trees and became the obstacle factors. After 10 years of greening practice, native tree species were successfully applied in Shanghai World Expo Park, and the impact of climate barriers on native tree species was smaller. In the introduction of exotic tree species, the provenance was divided into 2 climatic zones and 3 flora by adopting the method of climate similarity flora and combining with the cold and tropical tolerance map of plants, and nearly 20 species of color leaf ornamental tree species such as Acer rubrum were successfully introduced.
Key words:  landscape plant  climate obstacle factor  urban greening  suitable tree species  selection
