| 摘 要： | 基于塔克拉玛干沙漠腹地面积最大的天然孤立绿洲达理雅博依2015年1月—2016年2月太阳总辐射观测资料,运用H.L.Penman经验公式模拟计算了该地区2015年逐日总辐射累计量,模拟值与实测值的误差分析显示:本气候学方法成功模拟了沙漠腹地总辐射的年内变化趋势。使用模拟值估算得到达理雅博依绿洲2015年太阳总辐射累计量约为5 332.23 MJ·m-2。又以相同方法模拟了塔中气象站2015年3—5月总辐射变化,结果较达理雅博依的模拟更接近实测值,说明本模拟在塔克拉玛干沙漠腹地不同地点结果有效。

| Abstract: | The study of solar radiation include its characteristic and variation, is of great significance to explore regional ecology system formation and evolution. The Taklimakan Desert, the largest mobile desert in China, is located in the center of the Tarim Basin. The oasis study in this desert is important to understand ecosystem process in arid land. However, for traffic problem, the desert"s meteorology datum, especially solar radiation data (long period), are very scare, which brings difficult in related oasis ecosystem process further discuss. In this work, the Daliyaboyi, the largest isolated pristine oasis in the Taklimakan desert hinterland, was taken as a case study to simulate the solar radiation. The daily total solar radiation of the Daliyaboyi oasis cumulants in 2015 were simulated based on the H.L.Penman"s method Q=S0(a+bs). Using this formula, the simulated datum Q in the natural oasis had been derived, and then compared with observed datum to calculate the bias and absolute errors. The result shows that we selected method of climatological empirical formula successfully estimate the annual variation trend of the total radiation. Even though, there exist a slightly but relatively larger bias between simulated and measured results in calculating the solar radiation in spring. This is because the Taklimakan Desert"s sandstorm activities are more frequent in spring, which weakens radiation intensity of the sun reach the ground. Through our calculations, the relative error of simulated values was 0.77 %. The mean bias error, the mean absolute bias error and the root square error were -0.11,2.97,3.89 MJ·m-2·d-1 respectively. And the mean absolute percentage error was 21.02%. These show that the parameters of the empirical formula need to be further modified before simulating the solar radiation when applied to area around the Taklimakan desert hinter land . |
