Abstract
The performance features of different tree species and theirs arrangement pattern and different stand density of urban forest in Chenzhou City were investigated in the ice-snow disaster in March , 2008.The results showed as following :1)Different growth performance of the same tree species showed different compressive strength , the stronger the trees grew , the more compressive the trees showed .As for different tree species , the deciduous tree species showed stronger compressive than the ever-green ones , and the native tree species stronger than exotic ones .2)Different arrangement patterns also showed different compressive strength .Cluster planting had stronger compressive than single one , and mixed stands stronger than pure ones .3) The stands with rather lower density showed rather stronger compressive than the higher one .These results would be of high significance for directing urban forest construction.
