Comprehensive Evaluation And Application Of Aquatic Flowers In Jinan Gardens

Garden aquatic flowers as an important part of the garden water features,to raise the water landscape aesthetic,improving the water quality,building appropriate aquatic organisms on the ecological environment of life,has an irreplaceable role.To improve the degree of the beauty of the landscape water system,and to establish the reasonable system of aquatic flowers plant configuration,is important strategic direction in the development of modern city waterscape water system,is also a key construction project of the construction of urban wetland.Based on the field research,this paper uses the theories of ecology,statistics,design and other related disciplines,and uses literature research,field investigation,comprehensive evaluation,summarization and other methods to study the characteristics of Jinan garden Research on Comprehensive Evaluation and Application of Aquatic Flower.Field research is the Jinan garden of the major waters of field visits,combined with literature research data,in which the selection of representative 12 Jinan garden waters for detailed observation.Through the study of the relevant literatures of the study of aquatic flowers in Jinan,more than one year of field investigation in Jinan,and the aquatic flowers used in the planting of Jinan at this stage,the species of aquatic flowers that can be developed in Jinan area.A comprehensive finishing.A total of 98 species of aquatic flowers,including 38 kinds of wet flowers,32 kinds of water flowers,10 kinds of floating flowers,10 kinds of floating flowers and 10 kinds of submerged flowers.This paper summarizes the growth and landscape effects of the aquatic flowers in the seasons,and investigates the characteristics of the four seasons of the aquatic flowers.It records the phenological changes of the aquatic flowers and the application of the aquatic flowers in different waters Form,distribution characteristics and application frequency.Classification and sorting,drawing a different refinement of the table,comparative analysis.Screening 45 kinds of ornamental high aquatic flowers,the use of expert evaluation method,questionnaire survey and index and method,the expert evaluation of the classificationof experts.After the evaluation of the two rounds of experts,the evaluation of the classification results are as follows.There are 12 kinds of aquatic flowers with comprehensive evaluation grade Ⅰ :Nymphaea tetragona,Nelumbo nucifera,Phragmites australis,Arundo donax,Typha orientalis,Arundo Donax var.Versiocolor,Acorus calamus,Polygonum orientale,Canna generalis,Thalia dealbata,Iris pseudacorus,Iris ensata.Comprehensive evaluation for the Ⅱ level of a total of 16 kinds of aquatic flowers: Lythrum salicaria,Polygonum hydropiper,Typha minina,Alisma orientale,Caldesia parnassifolias,Nymphoides peltatum,Trapa bispinosa,Nuphar pumilum,Zizania caduciflora,Scirpus validus,Pontederia cordata,Eichhornia crassipes,Sagittaria trifolia,Euryale ferox,Monochoria korsakowii,Hydrocharis dubia.Comprehensive evaluation of grade Ⅲ aquatic flowers a total of 6kinds:Colocasia tonoimo,Cyperus alternifolius,Butomus umbellatus,Scirpus triqueter,Polygonum amphibium,Juncus effusus.Comprehensive evaluation for the Ⅳ level of aquatic flowers a total of 11 kinds:Oenanthe javanica,Myriophyllum verticillatum,Ranunculus sceleratus,Scirpus triangulatus,Potamogeton distinctus,Sium suave,Nasturtium officinale,Juncellus serotinus,Marsilea quadrifolia.,Rumex patientia,Mariscus umbellatus.According to the results of the comprehensive evaluation grading,the landscape plants with high scores were selected for landscape configuration.The Application Mode of Jinan Aquatic Flower.Combine the characteristics of each aquatic flower,such as the growth period of aquatic flowers,the height and color of growth,the design of aquatic flower application optimization model: a single species,two combinations and three or more combinations of aquatic flowers.And for the typical optimization of the appropriate place,the hydrostatic area,moving water area to make a configuration example.But also on the different forms of application of aquatic flowers to make a detailed description.The design and optimization of the aquatic flower application of some gardens in Jinan.
