民眾對常見野生草本植物之視覺偏好研究

A Study of Visual Preference for Wild herbaceous Plants

本研究之主要目的在探討民眾對各種常見野生草本植物之視覺偏好。研究中以12種常見野生草本植物種植於庭園之狀況進行探討，並以觀賞距離、植物本身之時令變化以及個人社經特性為研究變項，使用電腦模擬各植栽景觀之彩色照片，作為常見野生草本植物視覺偏好之環境刺激媒體，由民眾進行視覺偏好評分工作。主要研究結果如下：）1.民眾會因不同時令變化與觀賞距離，而對野生草本植物之偏好有所改變。）2.觀賞距離與時令變化，在民眾對紫茉莉與大花咸豐草之視覺偏好的影響，會產生交互作用。）3.性別與專業訓練影礬民眾對常見野生草本植物視覺偏好之程度非常輕微。）4.不同年齡層的民眾對常見野生草本植物常有不同之視覺偏好，且年齡在18歲以下以及46歲以上之民眾，偏好評值一般較其他年齡層民眾為高。

The purpose of this study is to explore the visual preference for twelve kinds of wild herbaceous plants. The variables were 'observer distance', 'seasonal change', and 'personal characteristics'. The authors used forty-eight color photos in this computer simulated experiment and asked respondents to answer a questionnaire. The results are summarized as followed: I .'Observer distance' and 'seasonal change' have significant influences on the preference for wild herbaceous plants. 2.'0bserver distance' and 'seasonal change' have interactive influences on the preference for Mirabilis jalapa and Bidens alba. 3.The degree of influence that the personal characteristics, such as·'sex' and 'professional training' have on the preference for usual wild herbaceous plants are slight. 4.People with different age often have different visual preferences for wild herbaceous plants. Furthermore, the preference level of people who are under sixteen years old and above forty-six years old is proved to be higher than other groups'regarding to their preferences.
