    摘要:

    針對河南省土壤旱情災(zāi)害頻發(fā),,地面土壤墑情監(jiān)測站監(jiān)測面積有限等問題,,將氣象干旱指數(shù)與遙感監(jiān)測模型相結(jié)合對土壤旱情開展預(yù)測研究。以2012—2021年間氣象資料計算的標(biāo)準(zhǔn)化降水蒸散指數(shù)(Standardized precipitation evapotranspiration index, SPEI)為依據(jù),,對作物缺水指數(shù)(Crop water scarcity index, CWSI),、植被供水指數(shù)(Vegetation supply water index, VSWI)、溫度植被干旱指數(shù)(Temperature vegetation drought index, TVDI)和條件植被溫度指數(shù)(Vegetation temperature condition index, VTCI)4個指數(shù)的干旱監(jiān)測效果進行適用性評價,,然后分析2012—2021年間河南省的TVDI空間分布規(guī)律和變化趨勢,,最后用ARIMA(Autoregressive integrated moving average)模型預(yù)測2022年土壤旱情。結(jié)果表明,,CWSI,、VSWI、VTCI研究結(jié)果不符合實際土壤墑情結(jié)果,,TVDI值與實地歷史記錄的土壤墑情變化趨勢整體一致,,總體呈現(xiàn)出河南省西北部、中部,、北部隨時間變化而呈增大趨勢,,且ARIMA模型預(yù)測的2022年土壤墑情結(jié)果效果良好,為河南省的農(nóng)業(yè)生產(chǎn)精準(zhǔn)管理提供參考依據(jù),。

    Abstract:

    Aim at the frequent soil drought disasters and the limited monitoring area of ground soil moisture monitoring stations in Henan Province, the meteorological drought index and remote sensing monitoring model were combined to predict soil drought. It was based on the standardized precipitation evapotranspiration index calculated by meteorological data from 2012 to 2021, and the drought monitoring effects of four indices of commonly used remote sensing models, namely crop water scarcity index, vegetation supply water index, temperature vegetation drought index and vegetation temperature condition index were evaluated. Taking 2019 as a typical drought year, the differences among the four indices were compared, and the spatial distribution and change trend of TVDI in Henan Province from 2012 to 2021 were analyzed. Finally, ARIMA model was used to predict soil drought in 2022. The results showed that the research results of CWSI, VSWI and VTCI were different from the actual results. Only the TVDI value was consistent with the change trend of soil moisture recorded in the field, and showed an increasing trend with time in the northwest, central and northern parts of Henan Province. The spatial evolution results showed that the coverage pixels of arid areas in 2019 accounted for 76%, which accounted for the largest proportion in this decade, and the soil moisture predicted by the ARIMA model in 2022 was consistent with the reality. On the basis of soil drought prediction, it can provide reference for the precise management of agricultural production in Henan Province.
