As an indispensable part of the rural landscape,rural residential treescape plays a significant role in improving the rural environment and creating the rural landscape. This paper took 10 typical villages in Zhuhai City as the study objects to investigate the tree species composition characteristics of 4 types of rural residential treescape,including courtyard forest,roadside forest,Fengshui forest and public recreational forest,and compare and analyze the differences of residential treescapes between ancient and modern villages. The results showed that: 1) the courtyard forest mainly consisted of fruit trees,eg. Dimocarpus longan,Clausena lansium,Litchi chinensis,Averrhoa carambola, Artocarpus heterophyllus, Citrus maxima, Annona squamosa, etc. Ornamental plants such as Bougainvillea glabra, Platycladus orientalis, Podocarpus macrophyllus, Aglaia odorata, Osmanthus fragrans,Plumeria rubra,etc. were found in the courtyard of the new villages; 2) the roadside forest was dominated by Ficus microcarpa,Dimocarpus longan,Musa nana,L. chinensis,C. lansium,Eriobotrya japonica,P. rubra and Bombax malabaricum,etc.,while F. microcarpa and D. longan had the largest amount; 3) In Fengshui forest,the dominant species were fruit species and timber species,eg. Acacia confusa,Eucalyptus robusta,F. microcarpa,Dendrocalamopsis oldhami,D. longan,and L. chinensis. Fengshui plants were preserved well in the ancient village,while gradually lost in the modern villages; and 4) the public recreational forest were dominated by the ornamental and shading species,including F. microcarpa,Celtis sinensis,Cinnamomum camphora,B. malabaricum and F.religiosa, etc.,among which F. microcarpa was the most common species. In general,the rural treescape of the ancient and modern villages was dominated by native plants. However,the tree species tend to be ornamental and the planting mode to be urbanized in the modern villages.
