Abstract:Taking Suseong Lake in Daegu Metropolitan City as the research object, behavioral observation method is used to analyze the user’s behavior of waterfront platform in summer and autumn. In order to reflect the differences between different platforms, seven platform characteristic indicators are developed. According to the relationship between the platform and water and the purpose of the platform, the waterfront platforms are divided into 6 types. By analyzing the number of people used,the length of stay and the types of activities, the results show that the most popular types are waterfront observation deck, water observation deck, multi-layer observation deck on the water and water boardwalk. The construction of the user’s favorite water-type platform should highlight the hydrophilicity, accessibility and diversity of vision, meanwhile, the construction of the above-ground platform should pay attention to accessibility, site selection and overlooking effect.
