| 中文摘要 | 本研究利用“視覺和諧”這一認知因素來評估山區河流工程的視覺質量。收集了台灣山區溪流中的護岸和防砂壩等工程結構的圖像。採用3組不同結構的植被侵入圖像進行問卷調查，共獲得154個有效樣本。我們使用統計分析來開發視覺和諧 H 模型，該模型與可見綠化 GR 的百分比有關，即植被變化的感知曲線。我們的數據與文獻的比較確定了 H 和 GR 之間關係的上限和下限曲線。我們發現“軟景觀”和“硬景觀”的物理元素——即可見水 WR、可見結構 IR 和結構 NR 上可見天然材料的百分比——影響了這種關係。結果表明，H 等同於視覺偏好 P，兩者都可以通過更好的綠色能見度（增加 GR 和 GR < 50%）、避免低水能見度（WR < 10%）或增加可見的天然材料的量來改善（ NR > 0.9)。結構的高可見性（IR > 0.3）可能會降低 H 和 P。我們最終提出了一個視覺和諧或偏好模型，涉及包含 GR、WR、IR 和 NR 的組合物理指標。這項研究的結果可能有助於改善或了解流工程設計的美學。 |
| 英文摘要 | This study uses the cognitive factor of “visual harmony” to assess the visual quality of stream engineering in a mountainous region. Images of engineering structures such as revetments and submerged dams in the mountain streams of Taiwan were collected. Three image groups with different structures invaded by vegetation were used for a questionnaire survey, which yielded 154 valid samples. We used statistical analysis to develop a model of visual harmony H with respect to the percentage of visible greenery GR, that is, the perceived curve of vegetation change. A comparison of our data with the literature determined the upper and lower bound curves of the relationship between H and GR. We found that the physical elements of “softscape” and “hardscape”—namely, percentage of visible water WR, visible structure IR, and visible natural material on the structure NR—affected this relationship. Results show that H is equivalent to visual preference P, and both can be improved by better green visibility (increasing GR and GR < 50%), avoiding low water visibility (WR < 10%), or increasing the amount of visible natural material (NR > 0.9). High visibility of the structures (IR > 0.3) may decrease H and P. We ultimately propose a visual harmony or preference model concerning a combined physical indicator that comprises GR, WR, IR and NR. Results of this study could be helpful to improve or access the aesthetics of stream engineering design. |
