摘要:

本文应用内蒙古自治区5个旗/县的19个墒情监测点的数据验证土壤墒情综合诊断模型在内蒙古区半干旱地区的适用性,建模使用2012—2014年的数据,模型验证使用2015年的数据。结果表明:模型在内蒙古自治区半干旱地区具有较好的适应性,验证合格率为94%以上;模型预测合格率与纬度、经度之间没有显著的相关关系,这是因为所有监测点都位于半干旱地区,降水量差异较小。墒情综合诊断模型可以应用于内蒙古境内半干旱地区。

Abstract: The data of 19 soil moisture monitoring sites in 5 counties in Inner Mongolia were used to verify the adaptability of integrated diagnostic mode of soil moisture in the semi-arid regions in Inner Mongolia. Model was established by the data of 2012-2014, and validated by the data of 2015. The results showed that the model had good adaptability in the semiarid regions of Inner Mongolia, and the qualification rate was over 94%. There was no obvious pattern between the qualification rate of the model’s prediction and latitude and longitude, because all monitoring sites were located in semi-arid areas and rainfall difference was small. In conclusion, integrated diagnostic model can be used in semi-arid areas of Inner Mongolia.
