Abstract:

To find out the current situation and characteristics of plant greening resources in Beibu Gulf coastal city parks of Guangxi, 52 standard plots of 10 parks in Beihai, Qinzhou and Fangchenggang of Guangxi Beibu Gulf were investigated by typical random sampling method. The statistical results show that there are 183 species of plant resources in this region, belonging to 60 families and 140 genera, including 1 species of pteridophytes in 1 family and 1 genus, 7 species of gymnosperms in 5 families and 7 genera, 175 species of angiosperms in 54 families and 132 genera. The arbor layer has the most abundant species, with 100 species, accounting for 55% of the total. The second is shrub layer, which has 56 species, accounting for 30% of the total. The herbaceous layer has the fewest species, only 27, accounting for 15% of the total. The plant system composition reflects the tropical, subtropical and coastal characteristics. Most species have regional landscape characteristics, mainly Roystonea regia, Archontophoenix alexandrae, Casuarina equisetifolia and etc. It is suggested to enhance the screening and application of native coastal plants for the greening construction of Beibu Gulf coastal areas.

Key words: landscape plants, plant diversity, park green space, Beibu Gulf, Guangxi
