Research On Perception Recovery Of Small Green Space Based On Landscape Quality Evaluation

Accelerated pace of life and the competitive pressure increasion makes city residents' mental load is in a long time in the overweight state, such long- term state of stress in overweight serious threat to people's health. K aplan proposed the Attention Restoration Theory which pointed out that when the attention of people due to excessive fatigue, the attractive environment could provide the best rest, this kind of environment has four characteristics, charming, escape, extended and compatibility. In this study, we evaluated the perceived recovery degree were evaluated of a small green space based on landscape quality assessment, to understand the impact of the different elements of the perception with landscape restoration degrees.In this study, we chose a small public green space in Harbin as the research object, then changed the vegetation, climate, facilities and management and other landscape quality evaluation factors in the field with virtual reality software, to build different scenes. A total of 9 animation had been bulit, including the status quo, as a medium for the study of the relationship between the quality of the landscape and the degree of recovery. Then, the scene animation was carried out in the form of video player in the virtual laboratory and the network, to carry out the questionnaire survey, and the results were analyzed by using statistical analysis software SPSS19.0, and then obtained the relationship between the quality of the landscape quality evaluation of the perceived recovery, as well as the perception of the relationship between the restoration and landscape preference.The analysis results showed that the quality of the landscape was different, and so did the degree of recovery. In the four evaluation factors, the greatest impact on perceived recovery was plant factor, followed by facilities, and then the climate factor, the impact of management. The correlation study showed that there was a positive correlation between the perceived recovery characteristics and perceived recovery and landscape preference, but the linear correlation was not found by stepwise regression analys is. In addition, the influence of different landscape evaluation factors on the recovery of perception was different, the effect of plant factor on the charming and the escape characteristic was the most significant, and the impact of the elements of the facilit ies on the compatibility and the escape from the influence of the factors was significant. By using principal component analysis, the four facters were eventually return to the natural features and environmental facilities in two dimensions. The main function of the two dimensions was the natural feature dimension.After the above research, it could be confirmed that the three research hypotheses were all established in this paper. The results of correlation analys is could provide reference basis for the perception of small public green space in the future, so as to further explore the relationship between landscape quality and perceived recovery.
