| The sunken square gradually emerged along with the development and utilization of the underground space system.Its appearance makes the urban three-dimensional space more complete.On the one hand,as a node space in the urban three-dimensional space,the city sunken square plays an important role in connecting the above-ground and underground spaces.On the other hand,as a three-dimensional form of urban squares,it has the characteristics of publicity and leisure of urban squares,and through effective combination with underground spaces,it has become an important public space for people to socially interact and entertain in the underground space system.Whether it is used as a node space in the urban three-dimensional space or a public activity space in the underground system,it has high requirements for the landscape environment quality of the city sunken square,especially the various disadvantages of the underground space environment require the city sunken square.The landscape environment can alleviate people’s negative emotions and enhance people’s sense of experience in underground space activities.According to the current research on city sunken squares,scholars mostly explore the landscape design strategy from the perspective of the designer,ignoring the user’s evaluation of the existing landscape environment quality.And most of the research is still based on traditional research and theoretical analysis methods,and there are few objective and quantitative research methods.In addition,after reviewing the relevant literature on landscape evaluation,the author found that the commonly used landscape evaluation methods are also subjective in the process of formulating evaluation element systems,setting questionnaires,and collecting questionnaire data.Based on the above analysis,this article takes landscape satisfaction as the comprehensive evaluation standard of landscape environment quality,introduces advanced eye-tracking technology and SD method,and from the user’s point of view,the subjectivity of urban sunken square landscape satisfaction(SD method)Evaluation)and objective evaluation(eye-movement evaluation),to explore the satisfaction of landscape quality of sunken square and its influence law with landscape elements and visual cognition respectively,to provide theoretical guidance suggestions for landscape planning of sunken square.At the same time,the subjective and objective evaluation results are compared and analyzed to explore the feasibility of the landscape satisfaction evaluation method based on eye movement analysis and construct an eye movement evaluation model,which provides an objective quantitative evaluation method for the landscape satisfaction research of sunken squares.The research results show that:(1)The subjective and objective urban Sag Square landscape satisfaction evaluation results are consistent,indicating that eye movement analysis is feasible for the Sag Square landscape satisfaction research,and according to the subject and guest evaluation Model comparison shows that eye movement evaluation is more objective and accurate than landscape element evaluation.(2)The percentage of total fixation time,average pupil diameter and average fixation time have an important mutual relationship with landscape satisfaction.Among them,the average pupil diameter,average fixation time and landscape satisfaction have a linear influence relationship.(3)Stayability and distinctiveness are two important criteria that affect the landscape satisfaction of the sunken square;enriching leisure and rest facilities,improving the comfort of the spatial scale and the sense of landscape coordination can enhance the stayability and characteristics of the sunken square Performance,thereby enhancing its landscape satisfaction;ground pavement,entry and exit design,and space enclosure have a small impact on landscape satisfaction;plant types and plant colors are not an important basis for measuring the landscape satisfaction of sunken squares.(4)The subjective evaluation of the satisfaction of the sunken square landscape between men and women does not have obvious differences.The difference in eye movement evaluation is mainly reflected in the number of blinks.The effort to obtain landscape information is greater than that of men. |
