Selection of Tree Species for Vegetation Restoration in the Rocky Desertification Areas of Northern Guangdong Province
Selection of correctly planted tree species is the key to vegetation restoration.This paper is based on the survey data of plant sample plots in rocky desertification areas of northern Guangdong was employed to es-tablish tree species selection and evaluation model,with integrating the six quantitative factors involving impor-tance valve,diameter,tree height,height to crown base,crown width,carbon stock.Application of entropy weight-TOPSIS comprehensive evaluation method to tree species selection,on the basis of the estimated values.The results show that:The plant diversity in rocky desertification areas is low,so when vegetation restoration is carried out,in the principle of"suitable land and suitable trees",tree species such as Pinus elliottii,P.massoniana,Loropetalum chinense,and Rhus chinensis can be used as the main extension tree species.Tree species Elaeocarpus decipiens,Osmanthus fragrans,can be used as supplementary tree species.
