Research On The Aquatic Plants Landscape Building Of Landscape Water In Xi’an City

As an important part of ecological city construction,landscape water plays an important role in improving the environmental quality of urban landscape.Aquatic plant landscape can not only enhance the ornamental function of landscape water,enrich the cultural connotation of landscape water,but also play a role in purifying water quality and optimizing water environment.However,many aquatic plants in landscape water are planted in a single way and the landscape effect is not good.This paper investigates the application of aquatic plants in landscape water in xi ’an,summarizing and analyzing the species,habits,application frequency and construction methods of aquatic plants.AHP analytic hierarchy process(AHP)is used to screen aquatic plants,which is suitable for landscape building.At the same time,the ideas and methods for aquatic plants landscaping in landscape water bodies are put forward.This paper mainly studies the aquatic plants landscaping in landscape water.Through field investigation,the application types and frequency of aquatic plants in landscape water in xi ’an are mastered.In this study,the author investigates 61 aquatic plants,and the results show that there are many species of aquatic plants,but the application frequency is low,and the plant landscape effect is poor.The analytic hierarchy process(AHP)is used to screen 61 kinds of aquatic plants,and the aquatic plants suitable for landscape building are selected through the two factors of ornamental value and ecological adaptability.Then,the landscape water body is analyzed from the aspects of landscaping theme,space construction,the elements combination of plant and garden,and planting ways so as to study the landscape building methods.Based on the above analysis,the paper puts forward the idea and method of aquatic plants landscape building.Firstly,the upper planning of landscape water is considered,and the site conditions are analyzed.Secondly,according to the positioning of landscape water,the theme of landscape construction of aquatic plants is determined.Then select the suitable aquatic plants according to the theme.Finally,make the plant space layout.Combining with garden architecture,stone,bridge and other elements,aquatic plants can make a planting design,and the plant configuration should take seasonal color of aquatic plants,as well as individual and group beauty into consideration.The study investigates 12 landscape water bodies in xi ’an,and 46 aquatic plants suitable for landscape building were screened.Based on the analysis of the Planting methods of aquatic plants in different landscape waters,the ideas and methods of aquatic plant construction are put forward,and the designing practice is carried out in xi’an new botanical garden.It is hoped that through the study,we can convey an idea and method of aquatic plants landscape building,and provide some lessons for future researchers,at the same time,push the research of aquatic plants landscape building to a deeper level.
