The result of typical sampling survey of plantation community in Maoming forest park revealed that there were 64 species,belonging to 55 genera and 34 families,in which there were 10 Pteridophytes belonging to 8 genera and 7 families,48 Dicotyledon belonging to 41 genera and 24 families and 5 Monocotyledon to 5 genera and 3 families.In addition,the predominant plants of Shrub Layer in the plant communities were Rhodomyrtus tomentosa,Psychotra rubra,Aprorosa dioica,Clerodendron cyrtophyllum,Mallotus apella,Clerodendron fortunatum,Embelia laeta,Bridelia tomentosa,while those of Herbaceous Layer were Dicranopteris dichotoma,Microstegium vagans,Eupatorium odoratum,Cyrtococcum patens,et al.The Richness and Shannon-wiener index of shrub layer were higher than those of herbaceous layer in different artificial communities,but the evenness was not the same.Shannon-Wiene index has a positive relationship with Evenness index,and these two indexes had a negative relationship with Species Richness Index.
