Combustibility Evaluation of 26 Landscape Tree Species in Shanghai

Abstract:

The combustion experiments of branches， leaves and cores of 26 landscape tree species in Shanghai were conducted. Fourteen combustion indexes including moisture content， bark thickness， specific leaf area， combustion calorific value， combustion time and temperature change were determined， of which the specific leaf area was the most important. The fire resistance characteristics of each tree species were evaluated comprehensively. Based on the analysis of variance， the correlation between the functional traits of tree species and the burning characteristics was elaborated. According to their burning characteristics， twenty-six species of landscape trees were divided into 3 categories： strong， medium， and weak. Then the optimal chain of landscape tree species selection for fire response in Shanghai was determined by cluster analysis at last.
