Study On The Evaluation Of Plant Landscape Of Aixihu Wetland Park In Nanchang City

With the development of related disciplines in landscape architecture,a great number of scholars and researchers has conducted numerous studies on landscape evaluation.There are different kinds of researches focus on different types and scales of landscape,studies on corresponding theories and practices related to landscape evaluation has attracted great attention.Wetland Park is a kind of park featured by landscapes,supplemented by leisure,education,and conservation-oriented landscape,which combines ecological and aesthetic values.The construction of urban plant communities is the premise of creating plant landscapes.Meanwhile,the core of wetland park construction is also based on plant landscapes.Therefore,landscape evaluation provides certain theoretical and practical guidance for the construction of plant landscapes.This thesis takes plant landscapes in urban wetland parks as the research object.Based on the available data collection and in-depth surveys,the research methods of multiple disciplines are applied to this thesis.The thesis focuses on plant landscape and adopts a comprehensive evaluation to figure out the specific factors that affect the landscape aesthetics and the configuration of plant landscape in the wetland parks.Meanwhile,the comprehensive evaluation method is adopted in this thesis.By using AHP to determine the indexes weight of evaluation,to measure people's perception of landscape and quantitative evaluation by using SBE,SD,which helps to change the subjective landscape evaluation into the objective data.The application of this method makes the landscape evaluation more practical and reliable.The relevant theories and researches of urban wetland park landscapes at home and abroad are delineated,and the advantages and disadvantages of landscape evaluation are comparatively analyzed in this thesis.This thesis takes the Aixi Lake Forest Wetland Park as an example,conducts the field surveys and collects the compilation of relevant data,a sample method was used to analyze the plant landscape in the Aixi Lake Forest Wetland Park to obtain corresponding quantitative evaluation indicators.By using AHP to calculate and analyze the quantification of the weight of the evaluation factors and landscape factors.It was concluded that the plant landscape level of the Aixi Lake Forest Wetland Park in Nanchang City is good ingeneral.Meanwhile,the important factors that affect the plant landscape are also ranked as qualitative indexes greater than quantitative indexes.In terms of qualitative indexes(ecological indexes),diversity of plant species,life structure,ornamental characteristics,landscape timing,and spatial types are important guarantee to the ecological aesthetics of plant landscapes in urban wetland parks.By using SBE to analyze the ratio of green looking,diversity of ornamental characteristics,richness of landscape levels,harmony of landscapes,and harmonization with the environment have a significant impact on the aesthetics of plant landscapes.Meanwhile,the linear relationship is obvious,which shows the value of significance is 0.015,0.029,0.036,0.017,and 0.030 respectively.However,diversity of plant species and succession landscape,plant landscape and hardiness exert influence on the aesthetics of the plant landscape.The linear relationship is less significant than the aesthetics of landscape quality,which indicates the value of significance is 0.079,0.066,and 0.060 respectively.By using SD to analyze the index of the sense of space,richness,depth,lightness,security,quietness,density,cleanliness,vegetation coverage,coordination,beauty,and attraction have different degrees of connection in the 46 samples of landscape.Meanwhile,the difference between the richness and the cleanliness is significant.This thesis has constructed a comprehensive evaluation system for the plant landscape of wetland parks,explores the method for optimal configuration of plant landscape in urban wetland parks with regional characteristics,which provides reference for the optimal configuration of plant landscapes.
