Research On Landscape Evaluation And Design Strategy Of Urban Wetland Park Based On Kansei Engineering

A city is a collection of large-scale man-made entities,and its construction and expansion will inevitably affect or even destroy the local native natural environment.This change not only has an impact on the natural environment,it is also difficult for human beings to adapt to the dramatic changes in the surrounding environment.The original intention of the Urban Wetland Park is to minimize such adverse effects,so that urban expansion has as little impact on the natural environment as possible.Urban wetland parks are a form of parks with equal emphasis on ecological protection and urban functions.They play an important role in ecological protection,cultural display,and provision of residents' activity venues.The particularity of Qianzhong's geographical conditions and cultural heritage requires that the urban wetland park in Qianzhong must consider the local ecology and culture,highlight its characteristics,and adapt measures to local conditions.However,the current planning and construction of urban wetland parks in central Guizhou mostly refers to the design mode of urban wetland parks in plain areas.The form and design methods are rigidly applied to the ecological and regional aspects and cannot highlight the artistic characteristics of the karst landscape in central Guizhou.In terms of sex,they lack the excavation and application of the cultural traditions of ethnic minorities in central Guizhou,such as the Buyi and Miao nationalities,and neglect the construction and maintenance of the recreational facilities that urban wetland parks should have in terms of comfort.This research aims to propose improvement strategies on the basis of evaluating the landscape environment of urban wetland parks from the perspective of visitors,so as to make the landscape modeling of urban wetland parks more in line with the aesthetics of visitors and meet their expectations of the landscape.The research results can not only provide useful suggestions for the construction of wetland parks in the specific environment of Gui'an New District,but also hope that the necessity of protecting the ecological environment is becoming increasingly prominent and the voice of protecting the ecological environment is becoming stronger today.As an example,it provides useful ideas for the planning of the relationship between people and the wetland during the construction of the wetland park.The methods used in this study include literature reading method,Delphi method,analytic hierarchy process,fuzzy mathematics method and other classification and evaluation methods.Perceptual engineering methods including brainwave measurement and semantic analysis were used to collect subjects' perception and evaluation of the Moon Lake Urban Wetland Park.The author first summarized the previous experience of urban wetland parks and perceptual engineering research through literature reading,and found that perceptual engineering methods are rarely used in the evaluation and research of landscape space.On this basis,the author uses the Delphi method,from the perspective of perceptual engineering,and uses the AHP method to construct an evaluation index system for urban wetland parks based on perceptual engineering,and assigns weights to it.Secondly,from the natural geography,history and culture of Gui'an New District,the author classified the landscape nodes of the Moon Lake Urban Wetland Park in Gui'an New District according to their relative positions to Moon Lake.Afterwards,through perceptual engineering methods,field walks and questionnaires,perceptual engineering evaluations of the Moon Lake Urban Wetland Park were collected.After collating the collected data,fuzzy mathematics is used to determine the final comment of the index,and the landscape perception characteristics of the Moon Lake Urban Wetland Park in Gui'an New District are summarized.Finally,based on the perceptual engineering evaluation and landscape perception characteristics of the Moon Lake Urban Wetland Park,the author redesigned the landscape of the Moon Lake Urban Wetland Park in terms of ecological restoration,landscape,road system,culture and architecture.Propose a design strategy.The main content of this research is divided into four parts:(1)By summarizing and combing the research results of urban wetland parks and perceptual engineering,propose a landscape evaluation system based on perceptual engineering methods(2)Comparing the Moon Lake Urban Wetland Park in Gui'an New District Research on the location,geographic characteristics and cultural attributes of the city,and use this as a basis to sort out and classify the landscape nodes in the Moon Lake Urban Wetland Park.(3)The methods of sound loudness measurement,brainwave measurement and semantic difference are used to collect physiological perception data of the landscape nodes in the Moon Lake Urban Wetland Park,and the landscape of the Moon Lake Urban Wetland Park is evaluated through the landscape evaluation system established in the pre-study.Evaluation(4)Combining the natural geography,historical and cultural characteristics of the Moon Lake Urban Wetland Park and the perception evaluation results of the landscape,design and propose design strategies for the Moon Lake Urban Wetland Park.The results of this research are as follows:(1)Through reading,sorting,summarizing and screening previous research methods,a total of 20 secondary indicators have been established with ecological,comfort,diversity,cultural and artistic as the first-level indicators,A hierarchical analysis and evaluation model of urban wetland parks based on perceptual engineering research methods,and weights are assigned to each indicator.(2)The Moon Lake Urban Wetland Park in Gui'an New District takes the surface of Moon Lake as the center,and forms different landscapes on its east,west,south and north shores.(3)In the perception evaluation of Moon Lake Urban Wetland Park,the evaluation of all the first-level indicators is good.Among them,comfort and diversity have the lowest scores,and there is a certain gap between ecological,cultural and artistic evaluations.The ecological score is the highest.(4)The design of the urban wetland park in Gui'an New Area must follow the principles of ecological system protection,environmental maintenance,enrichment of environmental elements,excavation and inheritance of regional culture,and the beauty of landscape artistic conception.Based on the above principles,the author made a landscape design for the Moon Lake Urban Wetland Park,and proposed design strategies for how to improve the comfort and diversity of the Moon Lake Urban Wetland Park.
