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。
This paper used the data of 12 monitoring sites of soil moisture in 4 counties of Hunan Province to verify the adaptability of integrated diagnosis model in humid regions of Central Chi- na. Model was established by the data of 12 monitoring sites in 4 counties in Hunan Province dur- ing the period of 2012-2014, and validated by the data of 2015. The results showed that the model had good adaptability in humid regions of Hunan Province, and the qualification rate was over 85%. The qualification rate of the model showed a tendency to increase with the decrease of average precipitation over the years.
