本研究旨在探討聯合分析法中文字敘述以及圖片輔助呈現方案方式受測者對各方案排序、偏好評估結果以及各類型設施願付費用之差異，以公園設施重要性為例，依文獻整理出四項公園設施屬性，包括遊憩及運動設施多樣性、植栽豐富性、有無提供藝文表演設施及水景，並以年入園使用費作為價格屬性，五項屬性採部分因子設計產生八種替選方案，於公園進行使用者問卷訪談。研究結果顯示，以文字描述及圖片輔助呈現替選方案方式，並不影響受測者的方案偏好排序及偏好校估模式之結果。進一步估算各方案之願付金額並比較兩種方案呈現方式之差異，結果並無顯著差異。然而各屬性相對重要性中僅以有無提供水景設施一項達顯著差異；而對各項設施每年願付費用則以遊憩及運動設施多樣性有顯著差異。

The purpose of this study is to compare the differences between verbal description and pictorial representation in preference ranking, preference score and willingness to pay for each alternative. Based on the results of previous studies, four major attributes of urban parks, including various recreational facilities, diverse vegetation, exhibition stage and water scenes, were selected. Annual entrance fee was designed as the price attribute. Eight alternatives were created by orthogonal design method. On site interview was conducted in urban park. Analysis results indicated that two alternative representations have no significant difference in preference ranking and preference score for eight alternatives. WTP for each alternative also has no significant difference between vocal and pictorial representations. However, there is difference between verbal and pictorial questionnaires in the relative importance for providing water scenes and recreational facilities in the WTP.
