【摘要】：本文應(yīng)用湖南省4個市縣的12個墑情監(jiān)測點(diǎn)的數(shù)據(jù)驗證土壤墑情綜合診斷模型在華中濕潤地區(qū)的適應(yīng)性,建模使用2012—2014年的數(shù)據(jù),模型驗證使用2015年的數(shù)據(jù)。結(jié)果表明:模型在湖南省濕潤地區(qū)具有較好的適應(yīng)性,驗證合格率平均為85%以上,模型合格率呈現(xiàn)隨多年平均降水量減少而提高的趨勢。
[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.
