摘要
本文利用2015年3月至2016年11月每旬逢8的0～20cm经过质量控制的自动土壤水分观测站实况数据和同期人工站数据对CLDAS土壤湿度模拟结果进行评估,结果表明:CLDAS能很好地模拟出鄂尔多斯市0～20cm土壤湿度的变化趋势;自动站数据与CLDAS数据拟合程度较人工观测数据要好;鄂尔多斯西部地区人工观测站点的相关系数较东部地区偏高,但东部地区的平均偏差和均方根误差较西部地区小,总体评估不如自动站数据。
In this paper, the results of CLDAS soil moisture simulation were evaluated by using the quality control da- ta of automatic soil moisture observation station from March 2015 to November 2016. The results showed that CLDAS could well simulate the variation trend of soil moisture of 0- 20cm in Ordos. The correlation coefficient of artificial observation stations in Western Ordos was higher than that in eastern Ordos, but the mean deviation and root mean square error in eastern Ordos were smaller than that in Western Ordos, and the overall evaluation was inferior to that of automatic observation stations.
