Landscape Quality Evaluation Of Coal Mining Collapsed Land Based On Eye Movement AnalysisAnalysis

Coal mining subsidence has caused great damage to the urban and rural ecological environment.With the improvement of people's living standards,higher requirements have been placed on the living environment.Therefore,the repair of coal mining subsidence areas has become a social problem that needs to be solved.However,the current researches on coal mining subsidence areas mainly focus on the methods of ecological reclamation of coal mining subsidence,the management of land where the coal mining has collapsed,and the evaluation of the ecological environment quality of coal mining subsidence.The landscape visual quality evaluation is very few.Through the literature study,it is found that the beauty evaluation method is a commonly used method for evaluating landscape quality,but it is found that there are certain limitations in the evaluation process of beauty,and the evaluation elements are also relatively independent,and there are deficiencies in the combination of factors;Can not reflect the psychological changes in the assessment process.The evaluation of landscape visual quality is the evaluation of the visual beauty of the landscape.The eye tracker is used to explore the intrinsic psychological activity or cognitive process through the recording and analysis of the eye movement trajectory when people observe external things.It can record the subconscious of people.Eye movement behavior,and through the analysis of "heat map","path map" and eye movement data can find out its potential visual aesthetic rules.This paper studies the coal mining subsidence in Xuzhou City as an example.Through the evaluation of the visual quality of the landscape,the eye movement evaluation is introduced.The correlation analysis,factor analysis and regression analysis of the data are performed by SPSS 22.0,and the comprehensive evaluation model is established.The differences in the subjects of different professions and genders were analyzed.Finally,suggestions were made for the landscape planning and design of coal mining subsidence areas.The research shows that it is feasible to evaluate the landscape quality based on the beauty degree evaluation method and supplemented by eye movement evaluation.It not only provides perfection and supplement to the beauty degree evaluation,but also improves the objectivity and accuracy of the landscape quality assessment to some extent.Sex,its comprehensive evaluation model is very representative.And found that subjects of differentprofessions and genders have no significant difference in average aesthetic value,but there are certain differences in eye movement data.
