【摘要】：本文應(yīng)用山西省2個(gè)市縣的16個(gè)墑情監(jiān)測(cè)點(diǎn)的數(shù)據(jù)驗(yàn)證土壤墑情綜合診斷模型在華北區(qū)半濕潤(rùn)地區(qū)的適應(yīng)性,建模使用2012—2014年的數(shù)據(jù),模型驗(yàn)證使用2015年的數(shù)據(jù)。結(jié)果表明:模型在山西省半濕潤(rùn)地區(qū)具有較好的適應(yīng)性,驗(yàn)證合格率為90%以上;由于2個(gè)監(jiān)測(cè)縣降水量接近,模型預(yù)測(cè)合格率與緯度、經(jīng)度之間沒有明顯的規(guī)律。本研究表明,墑情綜合診斷模型建模數(shù)據(jù)量大,數(shù)據(jù)范圍涵蓋了作物整個(gè)生長(zhǎng)季的數(shù)據(jù),相對(duì)于其他模型有一定的優(yōu)勢(shì),可以應(yīng)用于華北半濕潤(rùn)地區(qū)。
[Abstract]:In this paper, the data of 16 soil moisture monitoring points in 2 cities and counties of Shanxi Province are used to verify the adaptability of the comprehensive diagnosis model of soil moisture in the semi-humid area of North China. The data of 2012-2014 are used in the modeling and the data of 2015 are verified by the model.The results show that the model has good adaptability in the sub-humid area of Shanxi Province, and the qualification rate of verification is over 90%, and there is no obvious rule between the qualified rate and latitude and longitude because of the close precipitation in the two monitoring counties.This study shows that the model has a large amount of data and the range of data covers the whole growing season of crops. It has some advantages over other models and can be used in the sub-humid area of North China.
