Visual Quality Evaluation Of Harbin Wetland Park Landscape Based On Eye Movements Analysis

In the context of the restoration and construction of urban wetland park,the study of wetland park landscape has attracted the attention of experts and scholars at home and abroad.With the continuous development and utilization of Harbin wetland park,the visual quality problems in wetland conservation management and restoration have been exposed.Taking the Qunli national wetland park,Cultural center wetland park and Binjiang wetland park in Harbin city as the research objects,this paper adopts the eye movement analysis method combined with the subjective evaluation method to make a qualitative research on the landscape quality of the wetland park from the perspective of vision.In this paper,the aesthetic degree,landscape feature elements and eye movement index of the three parks are quantitatively studied from two aspects:eye movement analysis and subjective evaluation analysis.The comprehensive evaluation model of landscape visual quality was established and applied to evaluate Harbin wetland park.The results are as follows:(1)It is feasible to evaluate the visual quality of landscape by combining the eye movement analysis method with the subjective evaluation method.The two methods verify and complement each other,thus achieving the unity of the subjective evaluation and the objective evaluation,and improving the accuracy and comprehensiveness of the visual quality evaluation of landscape.(2)Through the supplement of subjective evaluation to the eye movement analysis method and the evaluation of various landscape elements from the perspective of visual aesthetics,the research shows that the buildings with unique natural shapes are more likely to attract people’s attention;Adequate plant coverage can promote the visual landscape effect of open water,while excessive plant coverage can inhibit the visual landscape effect of open water.The function and form of revetment influence people’s visual attraction;The reasonable combination of characteristic architectural sketch,road bridge,road bridge and landscape elements on both sides has a strong visual attraction.(3)The comprehensive evaluation model established based on the two evaluation methods is of high representativeness,which can explain the visual quality of the landscape from six aspects,such as the total fixation time,the number of eye jumps,the number of fixation,the coordination of the landscape,the architectural aesthetic feeling,and the willingness to go.The comprehensive evaluation model is used to evaluate the visual landscape quality of three wetland parks in Harbin and to sort out the landscape features of each park.The results show that the cultural center wetland park has the best visual landscape quality,followed by binjiang wetland park,and finally qunli national wetland park.In conclusion,eye movement analysis combined with the traditional subjective evaluation method can make a more objective and comprehensive evaluation on the visual quality of wetland park landscape,so as to provide a basis for the upgrading and renovation of Harbin wetland park.
