Study On Plants Landscape Aesthetic Evaluation Of Wetland Parks In Hefei

City wetland is an indispensable part of city ecosystem,it has strong ecological andsocial function,such as accumulated water, degradation of toxic substances,deposition ofnutrients, regulation of microclimate and conservation of biodiversity and other functions.But,many city wetlands are being destroyed by city construction along with thedevelopment of city, the ecological problems are increasing seriously. In order to moreeffectively protect the city wetland, many cities have started the construction of citywetland park on the heat, the academic circles have also carried out on the city wetland andwetland park, but relatively few studies on plant landscape of city wetland park,it providesa good opportunity for development of this research.This article firstly introduced the related concept of plant landscape of city wetlandpark and summarized the research dynamic at home and abroad; secondly analyzed theresearch purpose, significance and the technical route;then explore a set of scientific,practical evaluation method and indicator system from the view of aestheticevaluation;finally studied four wetland park in Hefei,researched on aesthetic evaluation oftheir’s plant landscape.The main contents and results of research as follows:（1）Summarized related concepts and development at home and abroad of city wetlandpark’s plant landscape.（2）This article’s evaluation method was determined by studying the aesthetic evaluationmethod of city wetland park’s plant landscape,it is the combining of the Analytic HierarchyProcess and Fuzzy Comprehensive Evaluation method.（3）Based on the research of evaluation method,that determined the route of evaluationtechnique in this paper:firstly determined the factors of aesthetic evaluation of city wetlandpark’s plant landscape;secondly used the method of AHP to establish evaluation indexsystem;and then determined the weights of evaluation factors and criteria;finallyestablished fuzzy valuation standard and got the results.（4）Analyzed the factors of aesthetic quality of city wetland park’s plant landscape by AHP,and got the sort of each factor’s weights: A-B layer value ordering,B₁（ecological beauty）>B₂（formal beauty）> B₄（artistic beauty）> B₃（space beauty）; in the B₁-C layer of B1（ecological beauty）,the importance degree of order, C₁（species diversity）>C₃（localcommunity）> C₆（water ecology）> C₇（anti-jamming ability）> C₂（community richness）>C₄（vegetation type）>C₅（community spatial heterogeneity）;in the B₂-C layer of B₂（formalbeauty）,the importance degree of order,C₈（ornamental feature）> C₁₁（waterfront landscape） > C₁₀（color and seasonal aspect）> C₁₂（harmony with small garden ornaments）> C₉（artcomposition）;in the B₃-C layer of B₃（space beauty）,the importance degree of order,C₁₄（landscape level）>C₁₅（human space）>C₁₃（space sequence）.（5）The paper studied four wetland park in Hefei,by collecting relevant data and fieldinvestigation,and combining landscape ecology,phytocoenology and landscape aestheticsand other disciplines, using sample method to survey the diversity of plant, speciesrichness and vegetation types of Zhongguo tiejian wetland park,Tangxi river wetlandpark,Paihe wetland park and Dazhangwei wetland park.This paper used the AHP-fuzzycomprehensive evaluation method to value16sample plots and carried out thatonly four sample plots’comprehensive quality to belong to class II, the rest are class III. Itexplained that the construction and building of wetland park’s plant landscape in Hefei stillneeded further development and improvement.
