摘要: 本文应用河南省3个市县的7个墒情监测点的数据验证土壤墒情综合诊断模型在华中区半湿润地区的适应性,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:模型在华中区河南省半湿润地区具有较好的适应性,验证合格率为80%以上;同一气候区,季节降水量的不同对模型预测合格率的影响可能更大,这为今后提高模型预测合格率指明了新的研究内容;墒情综合诊断模型可以应用于华中半湿润地区。

Abstract: The data of 7 soil moisture monitoring sites in 3 counties in Henan Province were applied to verify the adaptability of integrated diagnostic model of soil moisture in humid regions in Central China. Model was established by the data of 7 monitoring sites in 3 counties in Henan Province during the period of 2012-2014, and validated by the data of 2015. The results showed that the model had good adaptability in semi-humid regions of Henan Province, and the qualification rate was over 80%. In the same climatic region, the seasonal precipitation had a greater impact on the prediction qualification rate of the model, which indicated new research content for improving the prediction qualification rate of model in the future. Integrated diagnostic model can be used in semi-humid areas of Central China.
