| As the main public open space in the city,city park is an important reflection of the city's overall environmental level and residents'quality of life,and plays an important role in the lives of residents.Urban mountain parks are distinguished from other more artificial urban parks because of their rich terrain,primitive forest vegetation,and diverse spatial forms,and are a type of landscape with high sensitivity.With the rapid development of the country's urbanization process,people's quality of life is increasing,and the demand for outdoor leisure and recreation is also increasing.Therefore,urban mountain parks are more and more valued by citizens because of their particularity.It is particularly important to evaluate the visual quality of urban mountain parks and explore how to create a better mountain park landscape.Aiming at the particularity of urban mountain parks,this paper takes Gaogaishan Park in Fuzhou as the research object,and uses a combination of subjective and objective research methods to carry out landscape visual quality evaluation research.The evaluation mainly includes the evaluation of landscape visual sensitivity based on the level of the landscape's objective physical attributes,and the evaluation of subjective beauty based on the perception level of the landscape audience,and the introduction of eye movement analysis methods commonly used in the field of psychology in the study to explore people's subconscious landscape The law of visual aesthetic preference combines qualitative analysis and quantitative analysis.Finally,based on two levels of evaluation research,a comprehensive superposition analysis is carried out to obtain the landscape visual quality evaluation results of the park,then analyze them based on the results,and give suggestion for the development and construction of the park.The main conclusions of the paper are as follows:(1)In the evaluation of landscape visual sensitivity,this study analyzed and processed the DEM elevation data of Gaogai Mountain with the help of GIS-related technologies to obtain the visual sensitivity evaluation results of various landscapes in the park.The visual sensitivity evaluation results of each scenic spot are ranked as follows:Deyin Pavilion(3.45)>Foxian Temple(3.1629)>Sudden Terrace(2.9)>Taohuaxi-Guanyin Rock(2.8372)>Laojun Hall(2.7372)>Theater(2.3257)>North Entrance Square(2.295)>Martyrs Memorial Park(2.2564)>Nantian Temple(2.1551)>Gazebo(2.0936)>Magnolia Incense Path(2.0858)>Qinglong Pond(2.0308)>Fangsheng Pond(1.6358).(2)In the evaluation of landscape beauty,the scenic beauty of each scenic spot is ranked as follows:Yulan Fragrant Trail(0.3164)>Observation Deck(0.2825)>Foxian Temple(0.1557)>Qinglongchi(0.1324)>Fangshengchi(0.1208)>Theater(0.0803)>Sudden Terrace(0.0140)>Nantian Temple(-0.595)>North Entrance Plaza(-0.1134)>Taohuaxi-Guanyin Rock(-0.1758)>Deyin Pavilion(-0.1802)>Laojun Hall(-0.2848)>Martyrs Memorial Park(-0.4188).(3)In the eye movement analysis,for the different landscape pictures in Gaogaishan Park,the longer the average fixation time of the pictures with blurred boundaries of the landscape elements,the clearer the combination relationship,the more distinctive the landscape features,the shorter the average fixation time;Participants were more interested in the picture or the more abundant the landscape elements of the picture,and the longer the total time of gaze;the subjects were more interested in the landscape structures and text information such as buildings and sketches in the picture;The more concentrated the gaze range of the test,the greater the proportion of saccade time,and the greater the search interest of the subjects.For the pictures with obvious main scenes and easy to form visual focus,the average saccade amplitude of the subjects is smaller.(4)A regression model equation of beauty degree and eye movement index was established in the study:SBE=-2.510+0.157Xa+0.138Xb+0.097Xc+8.341Xd(R~2=0.790),where Xa is architecture and sketch,Xb is color Contrast,Xc is the plant configuration mode,Xd is the proportion of saccade time.There is a significant correlation between the degree of beauty and the eye movement index,indicating that there is a reliable correlation between the eye movement analysis and the subjective degree of beauty evaluation.The eye movement analysis method and the subjective evaluation can complement each other and are used in landscape visual quality The evaluation has objective feasibility.(5)Comprehensive research results include two aspects:landscape natural attributes and landscape perception.The comprehensive evaluation score of landscape visual quality of each scenic spot is:Deyin Pavilion(0.5064)>Foxian Temple(0.4378)>Huarantai(0.2746)>Peach Blossom Xi-Guanyin Rock(0.1420)>Magnolia Incense Path(0.0995)>Laojun Hall(0.0600)>Gazebo(-0.0896)>Nantian Temple(-0.1271)>Theater(-0.1649)>Qinglongchi(-0.2024)>Release Chi(-0.2988)>North Entrance Plaza(-0.3287)>Martyrs Memorial Park(-0.3750).(6)Divided into four landscape grades at equal intervals according to the visual quality comprehensive evaluation score,which are first-level landscape area(0.2861-0.5064),second-level landscape area(0.0657-0.2861),and third-level landscape area(-0.1546-0.0657),four-level landscape area(-0.3750--0.1546).The scenic spots in the first-level landscape area include Deyin Pavilion and Foxian Temple,the scenic spots in the second-level landscape area include Huarantai,Taohuaxi-Guanyin Rock,and Magnolia Fragrant Trail.The scenic spots in the fourth-level landscape area include theater,Qinglongchi,Fangshengchi,North Entrance Plaza,and Martyrs Memorial Park. |
