| Summary: | 碩士 === 國立臺灣大學 === 園藝學研究所 === 100 === The main purpose of this study is to determine the effect factors of landscape preferences, evaluate whether there are different perceived degrees of naturalness within different park contexts, and discuss the relationship between perceived naturalness and preferences in different park contexts. The research method was by field photography survey, and collection of stimuli by taking pictures in national and urban parks. After choosing 100 pictures as stimuli, respondents placed value on the abundance of vegetation, spontaneous nature, quantity of anthropic element, health, perceived naturalness, and preference. The results showed that perceived naturalness is negatively correlated to the quantity of anthropic elements and positively correlated to the abundance of vegetation, spontaneous nature, and health; with the main factors of perceived naturalness as spontaneous nature and health. Regarding the different contexts, perceived naturalness for respondents of urban parks is higher than the respondents of national parks. It was inferred that natural environments have higher standards of perceived naturalness than in artificial environments. In national parks, while perceived naturalness value is higher, the landscape preference value continues to increase. The regression model showed that perceived naturalness and perceived naturalness square can explain 14.8% of landscape preference for national parks. On the other hand, urban scenes showed an inverted U-shape curve was found between perceived naturalness and landscape preference, with 6.36 the most preferred perceived naturalness value. The regression model showed that perceived naturalness and squared perceived naturalness can explain 11.9% of landscape preference for urban parks. In conclusion, when respondents are in a rather natural environment, the higher perceived naturalness would lead to higher preference, and when respondent are in a rather artificial environment, the higher perceived naturalness would lead to higher preference; however, when perceived naturalness is higher than a certain extent, the preference will be reduced.
