摘　　要：基于群落调查、美景度评判及色彩定量分析,对陕西省金丝大峡谷国家森林公园的秋季景观林的色彩量化进行初步研究。结果表明:1)低海拔地区与高海拔地区相比,物种丰富度,多样性指数及均匀度指数都较高,落叶树种的种类较多,分布的科属范围也广;2)落叶树种单体色彩以黄色、黄橙色为主,群落景观的色彩构成主要包括红色、红黄色、黄色、黄绿色、绿色以及红紫色等,色彩数量受海拔的影响;3)当群落景观色彩斑块主色调为黄棕色、黄绿色、红棕色,3种颜色的斑块在群落色彩面积中占的比例分别为10.88%、9.33%和8.75%,且主色调斑块共占群落的28.97%时,美景度评价值最高;当群落景观色彩斑块主色调为黄棕色、黄绿色、棕色,分别占群落色彩面积的5.87%、5.82%和5.3%,且主色调斑块共占群落的16.99%时,美景度评价值最低。A preliminary study was conducted on the color quantization for the landscape of the fall scenic forests located in Jinsixia Canyon National Forest Park by using the methods of community curvey,SBE and color quantization.The results indicated that：1）in the low altitude region,the values of the species richness index R,the species diversity index H and the species evenness index E were higher than those in the high altitude region,there were more species of deciduous trees with wide distribution.2）The main colors of deciduous trees included yellow and yellow-orange.The color composition of community landscape included red,red-yellow,yellow-green,green and red-purple.The number of color patches was influenced by altitude.3）When the main color patches of the community presented as yellow-brown,yellow-green and red-brown,the proportions of the three color patches were 10.88%,9.33%,and 8.75% of the total color area of plant community.The highest evaluation value of scenic beauty was achieved when the ratios of the three color patches were 28.97%.When the main color patches of the community presented as yellowbrown,yellow-green,and brown,the proportions of the three color patches were 5.87%,5.82%,and 5.3%of the total color area.The value of scenic beauty was the lowest when the total ratio of the three color patches was 16.99%.
