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. |
