摘要： 基于新疆8个城市连续50 a（1961—2010年）的太阳辐射及气象数据，结合中国辐射光当量模型，获取各城市天然光年总照度值。应用MannKendall 检验方法，分析各城市天然光年总照度变化趋势及年际变化趋势。结果表明：年总照度变化幅度最大的城市为喀什，其年总照度降低2.4×108 lx•（10a）-1；年总照度变化幅度最小的城市为若羌，其年总照度降低1.1×108 lx•（10a）-1。城市年总照度年际变化趋势为喀什逐年递减；阿勒泰、乌鲁木齐、伊宁、哈密、吐鲁番及和田为先波动后下降，且下降趋势显著，若羌为先波动后下降，但下降趋势不显著。

Abstract: The total natural light illuminance values of 8 cities in Xinjiang Uygur Autonomous Region, China were obtained in this study based on the solar irradiance data and meteorological data of these cities in recent 50 years from 1961 to 2010. The luminous efficacy models were integrated in the data analysis. MannKendall test was adopted to analyze the overall and interannual change trends of total natural light illuminance values in these cities. Results showed that the overall change trends of total annual natural light illuminance values in Altay, Yining, Kashgar, Hotan, Urumqi, Turpan and Hami were extremely obvious, and the change trend in Ruoqiang was obvious. The change of total annual illuminance in Kashgar was the most significant and decreased by 2.4×108 lx•(10a)-1, and that in Ruoqiang was the lowest and decreased by 1.1×108 lx•(10a)-1. The interannual variation of total annual natural light illuminance in Kashgar was in a continuous decrease trend, that in Altay, Urumqi, Yining, Hami, Turpan and Hotan fluctuated at first and then decreased, that in Ruoqiang fluctuated at first and then decreased, but the decrease was not significant.
