本文利用高光谱技术分析了两幅模拟壁画，通过比较模拟壁画颜料与标准颜料光谱曲线的形状特征及其一阶导数特征峰和计算颜料光谱匹配度，有效准确地甄别出蓝铜矿、孔雀石、雌黄、藤黄、雄黄、铅丹和朱砂，但无法判别胭脂。同时，高光谱技术鉴定出的西藏拉萨大昭寺转经廊壁画中蓝铜矿、孔雀石、铅丹和朱砂颜料，与便携式 X 射线荧光元素成分结果一致。本研究结果表明高光谱技术可无损与准确地鉴定中国古代颜料，与便携式 X 射线荧光元素成分分析相结合，是壁画现场无损快速分析的重要手段。

Two simulated wall paintings were analyzed with hyperspectral technology and their spectral in-formation collected. Comparing their reflectance spectral curves, characteristic reflectance peaks, first derivative peaks and spectral similarity shared with wall paintings of standard pigments, we have effectively and accurately differentiated azurite, malachite, orpiment, realgar, gamboge, red lead, and cinnabar, though kermes could not be identified. In addition, the identification of pigments such as azurite, malachite, red lead, and cinnabar in the wall paintings at Jokhang Monastery in Lhasa, Tibet, can be verified by portable XRF analysis. This research in-dicates that hyperspectral technology combined with portable XRF is an effective method for non-destructive and large-scale in-situ investigation of mural pigments.
