海堤景觀之視覺評估模式建立

Abstract

親水性海堤及護岸為使用舒適感覺之建材，結合顏色、形狀之設計，並兼顧安全性而與自然環境相調和之海洋結構物，為未來海岸設施設計必然之趨勢。因此找出一套適合評估親水性海堤的方法乃是當務之急，本文的研究目的在於擬定一套較合理的海堤景觀評估模式，供設計規畫時參考。 在本研究當中，研究步驟主要分為四個階段。第一階段就現有景觀資源評估研究文獻加以分析研究，從其中選定三種常用的評估方法：SD法（Semantic Differential Method）、VIA法（視覺衝擊評估法 Visual Impact Analysis）、SBE法（景觀美質評估法Scenic Beauty Estimation Method）。第二階段中，先選出六張不同形式的海堤照片，再設計一套評估問卷，問卷內容分為兩部份：1.受訪者的背景資料，2.受訪者對海堤照片的反應程度。第三階段透過三種評估法來統計與分析問卷的結果。第四階段就各種評估法的結果加以分析與討論，並就分析的結果篩選出一種評估海堤的最佳評估方法。 由分析結果顯示SD法比較不適用於評估海堤景觀，但是由其評估因子之間的相關性，可以提供設計者在設計海堤時，做一個參考。其次VIA法與SBE法兩個則因為設計案的不同而有其適用的範圍。

Promenade breakwaters have been appreciated greatly since their comfortable materials, colors and forms have safety facilities and are in high harmony with the natural environment. For highly developed coast areas promenade breakwaters have been increasingly built abroad. However, there are no promenade breakwaters until now in Taiwan. Therefore, it is important to set up available evaluation models for future constructions of promenade breakwaters. The purpose of this paper is to propose some fair evaluation models for promenade breakwaters so that they can provide leading references for designing breakwaters. The research proceedings have four steps. The first step is to choose three previously proposed evaluation methods for landscape. These are SD method (Semantic Differential Method), VIA method (Visual Impact Analysis) and SBE method (Scenic Beauty Estimation Method). In the second step, we chose six different pictures about breakwaters, and designed a set of questionnaire in which both the background data of visitants and sensational measure are included. The third step is to statistically analyze all questionnaires. The last step is to explain final outcomes when we related them to corresponding factors by one-way Anova method. The results shows that SD method is a sensible examination but not a good evaluation for promenade breakwaters and only offers leading favorite factors of people for them. Secondly, Both VIA method and SBE method are suitable to evaluate the promenade breakwaters.
