摘要: The variation of the vegetation growing season in Three-Rivers Headwater Region Tibetan Plateau has recently become a controversial topic. One issue is that estimated local trend start (SOS) based on remote sensing data easily affected by outliers because this series short. In study, we determine spring minimum temperature most influential factor for SOS. significant negative linear relationship between two variables region evaluated using Moderate Resolution Imaging Spectroradiometer–Normalized Difference Vegetation Index 2000–13. We then reconstruct SOS time 1960–2013. regional mean shows an advancing 1.42 d (10 yr)−1 during 1960–2013, with occurring 160th and 151st days 1960 2013, respectively. enhances to 6.04 past 14 years. spatiotemporal variations reconstructed are similar those deduced from latter exhibit even larger [7.98 yr−1)] Arctic Oscillation found have significantly influenced changing SOS, especially eastern part region,
