Characteristics of the Coastal Plant Community and Ecological Restoration Proposal on Ka Ho Hill, Macau

To understand the characteristics of the coastal plant community and natural restoration with artificial help on Ka Ho Hill, Macau, species composition, species diversity, vertical structure and age structure were studied by field investigation. Results showed there were 82 species of vascular plants, belonging to 44 families and 76 genera in plots with areas of 1200 m². Liana phanerophyte, mesophanerophyte, microphanerophyte and nanophanerophyte species accounted for 86.59% of the life form spectrum of the community, with no megaphanerophytes found. The dominant community species were Litsea rotundifolia var. oblongifolia, Eurya nitida, Schefflera heptaphylla, and Sterculia lanceolata. Analysis on age structure indicated that the dominant populations expressed an increasing tendency. The height of communities on Ka Ho Hill was slightly lower than that of forest communities in Macau. Ka Ho Hill had latosol soil, and our study of vegetation restoration can provide a reference for the ecological restoration of seacoast with red soil. To accelerate the development of artificial forest into the local community, we selected 29 species of indigenous plants, and arranged a multi-layer, multi-species forest, and also suggested increasing species in both the upper layer and herb layer based on the characteristics of the Ka Ho Hill coastal community.
