摘要
为分析观景距离和光照条件对景观色彩呈现的影响,以八达岭国家森林公园红叶岭黄栌森林景观为研究对象,通过利用在不同观景距离、光照条件下拍摄的照片,设计试验,定量提取并计算HSV色彩,进行显著性检验等。结果表明:1)观景距离对景观色彩影响的试验中,Friedman秩和检验色彩全分量P值均远大于显著性水平α=0.05,色彩分量占比差值的T检验均以P值小于α=0.05拒绝μ≥0.1的原假设,即观景距离对森林景观色彩无明显影响。2)光照条件对景观色彩影响的试验中,Friedman检验全分量统计量均小于χ_(0.05)~2(12-1)=4.575,色相分量占比差值以92%的比例拒绝T检验的原假设μ≥0.1,彩度分量和明度分量分别以33%和27%的比例接受原假设μ≥0.1,即光照条件对景观色彩的色相分量无明显影响,对彩度和明度分量影响较大。3)本研究提出了使用色彩占比差值实施T检验的方法,对森林景观呈现进行定量分析,否定了观景距离、光照条件等客观因素对森林景观色彩呈现有较大影响的感性观点,为景观美学进一步研究提供了理论依据。
Forest landscape of Cotinus coggygria var. cinerea in Hongyeling in Badaling National Forest Park was studied to analyze effects of viewing distance and light conditions on landscape color rendering. Pictures taken under different viewing distances and lighting conditions were used, two experiment modes were designed, quantitative extraction and calculation of HSV color were made,and significance test were conducted. The results were shown below. 1) In the experiment of the influence of viewing distance on landscape color, p-value of the Friedman rank sum test was far greater than the significance level α=0.05, and the T test p-value of the difference of the color component ratio was smaller than α=0.05, rejecting the null hypothesis μ ≥ 0.1;That is, the viewing distance has no obvious influence on the color of the forest landscape. 2) In the experiment of the influence of light conditions on landscape color, the statistics of Friedman test was smaller than χ0.05^2(12-1)=4.575, the null hypothesis of T test was rejected by 92% hue component, what’s more, 33% saturation and 27% value component accepted the null hypothesis μ ≥ 0.1 respectively;In a word, lighting conditions had no significant effect on the hue components of the landscape color, and had some impact on the saturation and value components. 3) This study proposes a method of performing T-test using the difference in color ratio, the forest landscape presentation was quantitatively analyzed, the perceptual view that objective factors such as viewing distance and illumination conditions have a greater impact on the color of forest landscape was negated, and the findings provides a theoretical basis in aesthetics.
