【摘要】：本文应用湖南省4个市县的12个墒情监测点的数据验证土壤墒情综合诊断模型在华中湿润地区的适应性,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:模型在湖南省湿润地区具有较好的适应性,验证合格率平均为85%以上,模型合格率呈现随多年平均降水量减少而提高的趋势。
[Abstract]:In this paper, the data of 12 soil moisture monitoring points in 4 cities and counties of Hunan Province are used to verify the adaptability of the comprehensive diagnosis model of soil moisture in the humid area of central China. The data of 2012-2014 are used in the model and the data of 2015 are used in the model verification. The results show that the model has good adaptability in the humid area of Hunan Province, the average qualification rate of the model is more than 85%, and the qualified rate of the model increases with the decrease of annual average precipitation.
