基于灰色关联度分析的城市林荫道树种评价

Evaluation of Species for Urban Street Tree Based on Grey Correlation

在对上海12个城市林荫道树种多个性状指标观测的基础上,用灰色关联度分析方法求得各性状指标的关联系数及各树种与最优树种(理想树种)的关联度,评价城市林荫道树种。结果表明,上海城市林荫道树种表现较好的是悬铃木和珊瑚朴。

On the base of observing of 12 species for urban street trees against the property indicators, the study calculated the correlation factor of the different property indicators as well as the correlation degree of each spe- cies to the most applicable species by means of the grey correlation analysis method for the evaluation of these species. The results showed that Platanus acerifolia and Celtis julianae are the two best species that can be plan- ted as street trees.
