【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]:In this paper, the data of 19 soil moisture monitoring points in 5 banners / counties of Inner Mongolia Autonomous region are used to verify the applicability of the comprehensive diagnosis model of soil moisture in semi-arid areas of Inner Mongolia. The data from 2012 to 2014 are used for modeling, and the data for 2015 are verified by the model. The results show that the model has good adaptability in semi-arid areas of Inner Mongolia Autonomous region, and the qualified rate is more than 94%. There is no significant correlation between the qualified rate of the model and latitude and longitude, which is due to the fact that all the monitoring points are located in semi-arid areas and the difference of precipitation is small. The comprehensive diagnosis model of soil moisture can be applied to semi-arid areas in Inner Mongolia.
