色彩及碎形維度對自然景觀偏好之影響

The Effect of Color and Fractal Dimension on natural Landscape Preference

指導教授 : 林晏州

摘要


本研究之主要目的為利用客觀的測量工具,評估景觀色彩中明度、色相、彩度及色彩變異量等色彩屬性之變化與組合,以及畫面構成之複雜度等因子對人們自然景觀偏好之影響。在景觀色彩屬性方面,本研究利用Lab色彩空間作為表色方法將色彩量化,在景觀複雜度方面則以碎形維度作為複雜度的預測指標。本研究先從資料庫中選取大量自然景觀照片,利用軟體進行色彩屬性及碎形維度之數值分析,並根據分析結果,選出共210張包含各種不同色彩屬性及碎形維度變化之景觀照片作為刺激物。其中10張作為基準,將其餘200張分成兩組後,進行景觀偏好問卷調查,請受測者觀看照片後,根據其偏好以1~10分之等距尺度針對每張照片進行評分,並利用基準將偏好評值進行標準化處理,以消除因不同受測者個人評量尺度不同所造成之誤差。最後將所獲得之資料進行統計分析及假設之驗證,並建立綜合偏好預測迴歸模型。分析結果顯示在色彩屬性方面,景觀偏好與Lab色彩空間中之L值成負相關、與a值、a值之標準差、b平方值及彩度值成正相關;在碎形維度方面,景觀偏好與碎形維度值兩者之間為一倒U字形二次曲線關係,當碎形維度值為1.333時,景觀偏好值最高;在景觀偏好預測模型中,a值、b平方值、碎形維度值及其平方等4個變項皆可顯著解釋景觀偏好,迴歸模型之解釋力為20.4%。根據本研究之研究結果,人們在色彩方面偏好明度較低、色相偏紅、偏黃或偏藍且紅-綠變化多、色彩鮮豔或對比強烈之景觀;在複雜度方面則以複雜度中間偏低之景觀最受偏好。本研究證實Lab色彩空間可以有效將景觀照片中各項色彩屬性量化,且碎形維度可以作為景觀複雜度的預測指標,研究結果可以作為未來景觀偏好領域研究之參考。

The main purpose of this study is to evaluate the effect of different color qualities and complexity on people’s preferences for natural landscape. In this study, Lab color space is used to quantify color qualities, and Fractal Dimension is applied as the index of landscape complexity. In the beginning, large amount of landscape pictures were collected from the database built earlier. Then researcher used software to analyze each picture, calculating fractal dimension and the color qualities in Lab color space, including Brightness, Hue, Chroma and the variance of color. The final samples contained 210 pictures with varying color qualities and fractal dimension, including 10 Baseline pictures and two groups of 100 pictures each. Second, people’s landscape preferences of each picture were collected through a 10-point-scale questionnaire. Finally, the quantified data was analyzed to vertify the hypotheses. The result shows that people’s landscape preference is negative correlated to L, but positive correlated to a, aS.D., b2, and Chroma in Lab color space. An inverted U-shape curve was found between fractal dimension and landscape preference, 1.333 is the most preferred Db value. The regression model shows that a, b2, Db, Db2 can explain 20.4% of landscape preference. According to the results, people tend to prefer natural landscape which is darker in Brightness, more red, yellow or blue in Hue, more colorful in Saturation and more red-green variances in color, and lower-middle landscape complexity is preferred more. This study proves that Lab color space is an effective tool to quantify color qualities, and Fractal Dimension is a predictive index of landscape complexity. The results can contribute to future studies in the field of landscape preference.
