Abstract：This study proposed a deep learning-based model integrating Convolutional Neural Network （CNN），BidirectionalLongShort-TermMemory（BiLSTM）andatentionmechanismtopredictflaxyield.Themodelcombinedthe spatialfeature extractioncapabilityofCNN，the temporal dynamicmodelingabilityof BiLSTM，and the featureadaptive weighting functionof the Atentionmechanism.The model was trained using climatedata，vegetation indices，andyielddata during 2000-2020.Experimentalresultsshowed that theCNN-BiLSTM-Attntionmodel significantlyoutperformedtraditional models in prediction accuracy，with a root mean square error （ RMSE ）of 316.98kg/hm2 and a coefficient of determination （ R2 ）of 0.83.The model maintained good stabilityand high accuracy under interannual climate change conditions.This studyprovides technical supportforflaxyieldprediction，and itsmodulardesign frameworkcanalsobeextended tohe growth monitoring and yield prediction of other crops.

胡麻（油用亞麻）是亞麻科（Liancease）亞麻屬（Linum）的重要油料作物[1]，其籽粒富含不飽和脂肪酸（亞麻酸、亞油酸、油酸）、木酚素和亞麻膠等活性物質(zhì)，具有降血脂、降血壓、降血糖以及預(yù)防心腦血管疾病等功能[2]。（剩余11298字）
