Based on the comparative plots monitoring method,the characteristics of forest communities before and after rehabilitation in Shunde of Guangdong Province have been investigated.The main forest types in Shunde were Pinus elliottii,Eucalyptus exserta,and Acacia confuse plantations and were singularity in species composition and low biodiversity indexes before rehabilitation as well as the simple structure.After rehabilitation,the biodiversity index (Shannon-Weiner index) can be increased from 1.6 to 3.7 (calculated by species) or from 2.1 to 4.0 (calculated by important value of species).The tree DBH and Height class curves are becoming "reverse-J" type which is in good status of the forest structure and is favor of the community succession.The suggestion of the forest rehabilitation is to select the endemic broad-leaved species,to remain some tree-layer individuals (about 0.3 of the canopy density) and to remove them gradually in the next 2-5 years along with the endemic species growing.
