Abstract Phenology is highly responsive to environmental changes, particularly in ecologically vulnerable regions that have undergone significant anthropogenic management and rapid climate change. While previous research has mainly focused on interannual variations of specific phenological events such as the start (SOS), peak (POS), end (EOS) growing season, little attention been given abrupt shifts long‐term seasonality resulting from land management. In this study, we utilized full temporal details Moderate Resolution Imaging Spectroradiometer‐derived normalized difference vegetation index investigate how metrics changed within Loess Plateau. Our results indicated an earlier initial phase (SOS‐POS) a prolonged POS‐EOS phenophase. Earlier spring onset was dominated by increasing water availability autumn, SOS led POS but no carryover effect EOS. addition, grassland sensitive precipitation while forest community strongly influenced temperature. We also reported changes across plateau, shift controlled season precipitation. Moreover, use/land cover change played role with importance after seasonality. sum, our findings highlight shaping patterns semiarid plateau illuminate are indispensable comprehensive understanding phenology dynamics.
