| 景观意象作为游客主体和景观客体之间的映射，是

研究对象，通过Google Cloud Vision提供的在线机器学习
算法，自定义景观标签，构建Auto ML模型对16 883张网

景观的感知高于人文景观，其中水体景观、林木景观、历史文
化是湖泊公园的核心感知要素；大尺度空间广阔深远的自然景
观和小尺度精细化设计的人文景观更受游客偏好；常绿树、湖
泊、背景建筑群、草地和倒影是湖泊公园中感知最强的意象元

据图片实现景观偏好的相关研究提供了思路与参考。 |

| A Study on Landscape Image and Public Perception and Preferences of Lake Parks Based on Internet Photo Data and Auto ML Model |

| Abstract: |
| The study of landscape image serves as an important
theoretical basis for improving landscape attractiveness which
correlates the subject of tourists and the object of landscape. This
study used the online machine-learning algorithm provided by
Google Cloud Vision to categorize 16 883 landscape photos of
seven lake parks in Wuhan with the Auto ML model trained by
self-developed landscape tags, so as to conduct image mining and
content recognition. Then people's perceptions of different types
and elements of landscape, space dimensions and imagery elements
were analyzed to explore how common or different people's
preferences were towards these landscape images as well as the
factors affecting people's different perceptions. The results show
that: 1) the natural landscape of lake parks is better appreciated
than man-made landscape, among which waters, trees as well
as historical and cultural elements are the core factors affecting
people's perceptions; 2) natural landscape covering a large area
with a broad view and man-made landscape with delicate designs
covering a relatively small area are preferred by tourists; 3) evergreen
trees, lakes, background buildings, grass and water reflection are the
most appreciated imagery elements; and 4) landscape with unique
natural or man-made units are more likely to be highly appreciated
by tourists. Therefore, this study provides new observations on the
subjects and analytical methods of landscape image, and presents
some references for big data analysis of photos and landscape
preference. |
