摘　　要：为得到微环境参数对古建园林彩画色彩衰变量化影响规律,以颐和园为样本,选取颐和园典型彩画作为研究对象,并开发微环境参数监测系统,对彩画所处微环境信息进行全年实时监测,得到温湿度、风速及照度数据。同时,选取颐和园典型彩画进行周期性测试,提取彩画色坐标及亮度参数,并根据所采集的色彩信息计算出色彩的主波长及兴奋纯度,并拟合主波长、兴奋纯度、亮度随时间的衰变曲线。通过将微环境测试数据与色彩衰变曲线进行对比分析,发现温度、湿度、风速对彩画色彩影响较小,光照是造成彩画色彩衰变的主要因素,而且光照对彩画色相、亮度、兴奋纯度3个参数的影响程度不同,不同颜色受光照影响变化程度也有较大差异。A micro environment monitoring system has been developed to quantify the impact of micro environmental parameters on color decay of color paintings＇ at Chinese classical garden.The environment parameters including temperature,humidity,velocity and sunlight in micro environment is a were recorded for the whole year at the Summer Palace.Besides,the color parameters of color painting were recorded periodically.Then fit curve graphs were obtained with dominant wavelength,excitation purity and luminance changed over time.Comparative analysis of micro environmental test data and color decay curve revealed that the temperature,humidity and wind speed has slight impact on the color of color painting,while sunlight is the dominant factor responsible for the color decay of painting.The extents to which the sunlight affect dominantwavelength,excitation purity and luminancewere different.are different on and impact of sunlight on different colors are different.
