The indexes of diversity,dominance,evenness,contagion,isolation,fractal dimension,patch density,landscape fragment of inner habitat area are used to study diversity of type,pattern and patch of forest landscape in Guangzhou area.The results show that:the pine forest is outstanding and orchard developed very quickly in Guangzhou area.Mean patch areas are large,patch density indexes are low and isolation indexes are small in pine forest and evergreen broad-leaf forest.In contrast,the patch areas are small, density indexes and isolation indexes are high in orchard,bamboo forest and China fir forest.Diversity index of forest landscape types in Guangzhou area is a little less than thatin Fujian Province.Above forest landscape characteristics in Guangzhou area is highly relative to human activity.
The courtyards of low density dwellings provided opportunities for the residents to design their garden landscape. Some 1460 houses scattered throughout 38 streets in three districts in Guangzhou and Hong Kong were studied in detail. The characteristics and its long-term prospects of this kind of landscape were explored in the light of the findings. Implications for landscape planning and management of similar courtyards in the south subtropical zone were discussed.
