Research On Application And Configuration Mode Of Zingiberaceae Plants In Waterscape At Pearl River Delta

Since the 20 th century,the construction of water landscape has received more and more attention from the society.Creating a rich and beautiful water landscape is inseparable from the configuration and application of waterscape plants.Nowadays,the society advocates the construction of ecological gardens and health-care gardens.The Zingiberaceae resources are extensive,and there are many distribution areas.It has not only medicinal and edible value,but also has good ornamental value,and its flower colour,flowering period and plant height are diversified.It can also release aromatic odour,soothe people's emotions and provide for people's viewing.Ecologically,it can sterilize and purify the body of water.Through reasonable collocation,it can form a landscape effect with high and low patchwork,flower colour,and flowering period.Therefore,this article through the field survey and analysis of the waterscape plants and water plants of Zingiberaceae,and through the summary and induction,draw the following conclusions and results:(1)By investigating the waterscapes of 23 parks in the Pearl River Delta region,127 species of water-banking plants were recorded in the Pearl River Delta Park,belonging to 80 families and 119 genera.There were 54 species of arbors,accounting for 42.5%;53 species of bushes and ground cover plants,accounting for 41.7%;20species of aquatic plants,accounting for 15.7%.The analysis showed that there were few aromatic plants,the flora was tropical,there were many exotic species,and many native soil wet plants were not used.This shows that the application of waterscape ornamental plants is relatively limited,resulting in the phenomenon that most landscapes are stereotyped and there are few plant species.(2)According to the results of a sample survey on the waterscape of the Pearl River Delta.We found that ten species of Zingiberaceae in the park,Alpinia zerumbet;Alpinia zerumbet(Pers.);Alpinia oxyphylla Miq,Alpinia katsumadai Hayata;Costus speciosus;Zingiber zerumbet;Amomum longiligular;Hedychium coronarium;Amomum villosum;Alpinia pumila,the common use is just two species,Alpinia zerumbet and Alpinia zerumbet(Pers.)There are too few kinds of Zingiberaceae in the waterscape,and many Zingiberaceae can suitable for planting in the water have not been fully utilized.In the water landscape,there are generally categorized species such as Taxodium distichum;Plumeria rubra L;Lagerstroemia indica L;Alocasiamacrorrhiza;Monstera deliciosa;Philodenron selloum Koch;Nymphaea tetragona;Thalia dealbata;Nelumbo nucifera;Canna indica L.;Cyperus alternifolius L.(3)Through the analysis of tree species distribution,landscape planar structure,landscape vertical structure and landscape quarter-phase structure of aquatic plants of Zingiberaceae,overall,the transitional differences of terrestrial plants,shore-side plants,and aquatic plants of planar structures are relatively significant,and it needs improvement.In particular,plant communities with vertical structures have a relatively simple configuration,and the landscape sense is not apparent enough.Regarding seasons,plant selection is an evergreen plant and lacks changes in the scenery of the four seasons.(4)Through the above investigation,the analysis sums up the advantages and disadvantages of the current water features and the current status of the water-based Zingiberaceae,combined with the basis for the allocation of water resources for Zingiberaceae(viewing value,ecological adaptability,and landscape application potential),and selecting 30 species that can be applied very well zingiberaceae plants in waterscapes,including Hedychium,Curcuma,Alpinia,Kaempferia L,Amomum L,Zingiber,Costus,as well as configuration structure,configuration techniques and principles,targeting six different waterscapes,Artificial revetment water features,natural reclaimed water features,stream-type water features,green island-style water features,adjacent water features,and small face-shaped water features are proposed to provide correspondingly different patterns of water-based ginger configuration mode.(5)Finally,I will summarize the distribution patterns of zingiberaceae in different waterscape,combine the site status;design concepts and principles,and apply them to discuss the distribution of plants in Saye farm.
