Abstract: The site of this study is Da'an Forest Park in Taipei. It studies the influence of space composition on users' behavior to find different needs of different users. The user's activity types can be divided into two categories: static activities and dynamic activities. The study uses space closures, and landscape elements to study the requirement of various activities. Research findings show that different users need different space. The spatial closure degree increases gradually when the activity transformation direction is from the competitive dynamic activity to the leisure dynamic activity, to the exercise dynamic activity, to the social static activity, then to the non-social static activity. The space more people prefer may have the following characteristics: 1) have one focus; 2) space closures; 3) have a certain degree of openness; 4) have a shade. This study can help landscape designers learn more about the behavior of users and to design better.
