Abstract:【Objective】To mitigate theriskoffreezing injury to ChineseoliveinFuzhou,clasificationcriteriaof Chinese olivefreezing injurylevelisestablishedinthisstudy.【Method】Through fieldinvestigationofhistoricalChineseolive frezing injury events,literature reviewand orchard observation,6O samplesofChinese olive frezing injuryin Fuzhou from1991to 2024 were collected.Acording to morphological characteristics of Chinese olive freezing injurysymptoms, Chinese olivefrezing injurywas clasified intofivelevels:none,light,moderate,severe,andextreme.Afiting equation between Chineseolive freezing injury levelanddailyminimum temperatureoforchardsisdeveloped.And through classificationanalysismethod,meteorological clasificationcriteriaofFuzhou Chineseolive frezing injurylevel is established.【Result】Freezing injuryto Chinese oliveisclassified into five levels,withcoresponding thresholdvaluesof dailyminimum temperature(T ⋅min )oforchardsas follows:none freezinginjury(Level 0 ):T ; light freezing injury(Level 1): -2.5∘Cmin⩽-1.5∘C ;moderate freezing injury(Level2): -3.0∘Cmin⩽-2.5∘C ; severe freezing injury(Level 3): -3.5∘Cmin⩽-3.0∘C ; extreme freezing injury(Level 4): Γmin⩽-3.5∘C . Through geographical transplantation testsandcomparativevalidationof Chinese olivefrezing injury events in typical years,theestablished classificationcriteriaofChineseolivefreezing injurylevelshowedahighconsistencywithactualconditionsofChinese olive in Fuzhou. The matching rate reached 80% orabove.【Conclusion】 The results indicated that the classification criteriaofFuzhou Chineseolive freezing injury level can providereferences forthemonitoring andearly warningof Chinese olive freeze damage.
