摘要/Abstract

摘要： 景观美学质量评价是森林资源管理体系中的重要环节,色彩是秋季景观林的重要组成部分,色彩的定量分析及科学地进行景观美学质量评价对秋季景观林的经营管理具有重要意义。本研究通过美景度评判法评估川西亚高山秋季景观林整体的美学质量,根据人眼视觉特性从色彩组成和色彩空间格局两方面定量分析色彩特征对秋季景观林观赏价值的影响。结果表明: 根据美景度值将川西亚高山秋季景观林景观美学质量从高到低划分为5个等级(Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ),71.5%的景观属于Ⅰ、Ⅱ、Ⅲ等级,说明川西亚高山秋季景观林具有较高的观赏价值;按美景度值大小排序,阔叶混交林的景观美学质量大于针阔混交林和纯林;在色彩要素综合指标评价体系中,按指标权重大小排序,色彩斑块异质性因子>秋季主色调因子>色彩饱和度与明度因子>色彩多样性与均匀度因子;通过聚类分析将川西亚高山秋季景观分为3类,其中,观赏价值较高的秋季景观林具有斑块破碎化和异质性程度大、秋季彩色占比大、绿色占比小、高明度和高饱和度、高色彩多样性指数和高均匀度指数的色彩特征;群落中植物或彩叶植物越丰富,多样性和均匀度指数越高,美景度值越大。在秋季景观林的打造中,应注重色彩的多样性和破碎化处理,通过种植和培育叶色多样且色泽鲜亮的树种来提高秋季景观林的美学质量。

Abstract: Evaluation of landscape aesthetic quality is a key step in the management system of forest resource. Color is an important component of autumn landscape forest, and quantitative analysis of color and scientific evaluation of landscape aesthetic quality are important for the management of autumn landscape forest. We assessed the aesthetic quality of autumn landscape forest using scenic beauty estimation and analyzed the effects of color characteristics on ornamental value of autumn landscape forest based on color composition and color spatial pattern according to human’s visual characteristics. The results showed that the overall landscape quality of subalpine region of western Sichuan could be divided into five grades according to beauty value (I to V). About 71.5% of autumn landscape forests could be classified into grade I, II, and III, indicating that autumn landscape forests of subalpine region in western Sichuan had higher ornamental value. According to the scenic beauty estimation value, the landscape aesthetic quality of broadleaved mixed forests was higher than that of coniferous and broadleaved mixed forests and pure forests. In terms of the comprehensive index evaluation system of color elements, the index weight coefficient order was landscape patch heterogeneity factors>autumn main color factors>color saturation and brightness factors>color diversity and evenness factors. With cluster analysis, autumn landscape forests of western Sichuan could be divided into three types. The forests with higher ornamental value showed following characteristics: larger degree of patch fragmentation and heterogeneity, higher percentage of orange and yellow and lower percentage of green in autumn, higher percentage of color saturation and brightness, and higher color diversity and uniformity index. The communities with higher richness, species diversity and evenness index would have higher beauty values. We concluded that species diversity and fragmentation of colors should be considered in the construction of autumn landscape forests, and that aesthetic quality of autumn landscape forest could be improved by planting and cultivating tree species with various and bright autumn leaf colors.
