Landscape Quality Evaluation Of Chengdu Luoshui Wetland Park Based On Analytic Hierarchy Process And Fuzzy Comprehensive Evaluation Method

In recent years,China has attached great importance to the principles of respecting nature,protecting nature,conforming to nature,and integrating ecological civilization construction into all aspects and all processes of economic,political,cultural,and social development.Urban wetland park plays an important ecological role in the urban landscape,and its landscape evaluation will help promote the establishment of evaluation performance systems for various types of parks in urban wetland parks and the entire city,as well as provide construction for the protection and restoration of the ecological environment opinions and strategies.This paper constructs an evaluation system composed of a target layer,three project layers,eleven factor layers and thirty-three indicator layers by using AHP and FCE fuzzy comprehensive evaluation method.We used Excel and Yaahp 10.2 to analyze the landscape quality.Through multiple methods,we explored the qualitative and quantitative evaluation of the tourists’ landscape quality in three different aspects: material,cultural emotion and ecology.The main conclusions are as follows:(1)By establishing an evaluation system for the landscape quality evaluation of Luoshui Wetland Park,the project weights and rankings at each level are obtained,and the target layer weights are as follows: ecological level B3(0.5695),material level B1(0.3331),The cultural sentiment level B2(0.0974)shows that the ecological level is the core evaluation element in the entire park landscape quality evaluation.At the same time,from the top to the bottom,the weight and ranking of each index of the factor layer and the project layer are also calculated.(2)Perform data analysis based on the on-site questionnaire to obtain the respondents’ personal attribute characteristics,travel analysis,analysis of the use frequency and time of urban wetland parks,cognitive analysis of wetland parks,and analysis of the activities of the park.(3)By using FCE fuzzy evaluation method,AHP analytic method and yaahp10.2software,comprehensive expert weights and on-site questionnaire scores are calculated,and the specific scores and weight rankings for each level are obtained,and the evaluation index conclusions are made for each level corresponding analysis.(4)According to the score ranking results of each level,it can be seen that the current Luoshui Wetland Park in Chengdu has low scores for landscape elements in terms of cultural heritage protection,plant configuration and form color aesthetics,scientific research popularization,ecology,etc.An optimization strategy is proposed.The construction of the landscape quality system of Luoshui Wetland Park also provides suggestions for building a livable city and improving the quality of the city wetland park landscape.
