Urbanization is becoming one of the most important drivers of global environmental change as human population and economic development rapidly increase. However, the effects of urbanization on plant phenology are still poorly understood, especially for leaf senescence and growing season length across large spatial scales. We aimed to fill this knowledge gap by combining in situ observations and remote sensing phenological data.

城市化延迟了植物叶片衰老并延长了寒冷地区的生长季节长度，但在北半球温暖地区则不然

随着人口和经济发展的迅速增加，城市化正在成为全球环境变化的最重要驱动因素之一。然而，城市化对植物物候学的影响仍然知之甚少，尤其是在大空间尺度上的叶片衰老和生长季节长度。我们旨在通过结合原位观测和遥感物候数据来填补这一知识空白。
