Study On Animation Media-based Perceived Safety Evaluation On Visual Landscape Of Urban Park Plants

Perceived safety is the most basic mental feeling of people in the outdoor environmental activities,it directly affects people’s other feelings and behaviors.The plant landscape in urban parks always brings positive meanings,such as beautifying the environment,adjusting the microclimate,relieving the emotion of the citizens;the previous researches pay more attention to people’s preferences and rules on plant landscapes.This paper takes the people’s basic needs towards the perceived safety in park plant landscape space as the research direction.This paper researches the effects of the relevant factors in park plant landscape space on people’s perceived safety,the relationships among perceived safety,preferences and stay willing,and the similarities and differences rules of the perceived safety of the people with different characteristics in the park plant landscape space,to reveal the internal relations of the effects of park plant landscape construction on people’s perceived safety.This paper refers to the theory and method of visual landscape evaluation,and firstly puts forward to use the landscape animation as the media of evaluation.Experimental demonstration shows that,in the overall evaluation of plant visual landscape perception,using landscape animation media for real scenery replacement is more effective than using photo media,the animation media have obvious replacement advantages in the evaluation of actual plant landscape in the aspects of perceived safety and preference perception attributes;However,in the plant landscape with an area of more than 4000M,the replacement effect of the animation and photo to the real scenery begins to weaken.There are 4 groups(24 in total)of plant landscape animation with different characteristics made in accordance with the plant landscape space factors(planting method,permeability,size of the space),and 1481 persons evaluated successively in the method of online questionnaires and WeChat push.The following conclusions are drawn:(1)Planting method,permeability and the size of the space has significant effects on the evaluation of the plant landscape’s perceived safety;The natural planting method has a higher perceived safety than the regular planting method;the permeability of the plant landscape space is larger,the perceived safety of people is higher;and the space of the plant landscape is larger,the perceived safety of people is higher.(2)The sequence of the plant landscape space factors that affect the perceived safety,in accordance with the significance of the effect is:permeability>the size of the space>the composite effect of permeability and the size of the space>planting method(3)There’s a significant positive correlation between the perceived safety on plant landscape space and preferences,i.e.,the perceived safety is higher,the preference is higher.The sequence of the plant landscape space factors that affect people’s preference,in accordance with the significance of the effect,is:planting method>the composite effect of the permeability and the size of the space>the composite effect of the permeability and planting method.(4)The stay willing in the plant landscape space environment is jointly affected by the perceived safety and preferences,both of the perceived safety and preferences have a positive correlation with the stay willing.(5)The following conclusion can be drawn by analyzing the perceived safety evaluation of the people with different population characteristics on plant visual landscape:In the park plant landscape space,the perceived safety of the male is higher than that of the female,the perceived safety of middle-aged is higher than that of the elder and the younger,the perceived safety of the people with a high school background is higher than that of the people with other backgrounds,the perceived safety of the middle-low income community is higher than that of high-income community and non-fixed income community,the perceived safety of the farmer,migrant worker and civil servant populations is higher than other populations,and the population with the experience of invading and harassing has a lower perceived safety evaluation.(6)Among the population characteristics affecting the plant visual landscape perceived safety evaluation,the effect of the sex is most significant,and the next one is the suffering invading and harassing of the lawbreakers;among the factors of the population characteristics,the sex has the most significant effect on the preference,followed by the age.The research concludes that the construction of plant landscape in urban parks needs to pay attention to the requirements of permeability.This research provides more references for the future research methods of plant visual landscape evaluation and evaluation media.With the development of computer technology,the urban park plant visual landscape evaluation research,with the help of landscape animation media,will be more convenient and more objective.
