Author:Cao Teng Major:Forestry Supervisor:Xu Xuehua
Abstract
In this dissertation,two site types in the hilly area of Taihang Mountain in Hebei Province and 5 vegetation restoration tree species(Cotinus coggygria,Prunus serrulata var. Lannesiana,Forsythia suspensa,Jasminum nudiflorum and Lonicera japonica)were the research field investigation and lab analysis,the ecological benefit and landscape benefit of the vegetation restoration were purpose is to provide reference for the selection of tree species and vegetation restoration in the main results are as follows:
(1)Among shrub herbaceous species for vegetation restoration,the biomass increment
of Cotinus coggygria after 2 years was more than that of Prunus serrulata var.￡口刀咒巴s砌n口.
The biomass distribution in an of Cotinus coggygria and Prunus serrulata vat.
Lannesiana was stem>root> 4 years of terrace slope vegetation restoration,the tree species biomass increment order Was Lonicera japonica>Forsythia suspense> Jasminum biomass allocation rates of Lonicera japonica, Forsythia suspensa and Jasminum nudiflorum were lower than on the ground.
(2)The herbaceous plant in the forest of vegetation restoration in shrub and
herbaceous slope Was renascent herb and annual the number of bieImial herb was less than the renascent herb and annual and evenness of herbage Was highest parison of shrub and herbaceous slope,and the dominance and richness were the Cotinus coggygria forest,herb dominance Was the highest,and diversity Was the Prunus serrulata Var
