Investigation on ornamental plant resources in Nanning Camellia Park

Objective]Non-camellia ornamental plant resources and afforestation status were investigated in Nanning Camellia Park in order to provide references for selection, analysis and evaluation of plant resources, and landscape design and garden building. Method]Non-camellia ornamental plant resources in Nanning Camellia Park were analyzed and assessed through field survey and literature reference. Result]It was found that the park had 193 species of ornamental plants belonging to 70 families and 149 genera. There were 64 species of local plants accounting for 33.16% of the total species in the park, and the exotic plants occupied 37.82%. There were 124 species of woody plants as the major ornamental plants, and ratio of deciduous trees to evergreen trees was 1∶3.8. Based on the statistics of ornamental characteristics, the ratio of fruit ornamentals∶appearance-viewing plants∶flower ornamentals∶foliage plants was 1∶4.7∶4.8∶5.7. Conclusion]In light of afforestation status in Nanning Camellia Park and experiences from other Nanning parks, it was suggested that local plants should take full advantage of constructing regional special landscape; aquatic plants should be introduced to enrich wetland scenery diversity and vine plants varieties should be supplemented to build vertical green landscape in parks.
