据广泛报道，城市环境改变了叶子和开花的物候期；然而，目前尚不清楚土地路面是否与这些变化相关。本文将中国北方两种常见的落叶城市树木水曲柳 (Fraxinus chinensis) 和元宝枫 (Acer truncatum) 以三种间距（0.5 m × 0.5 m、1.0 m × 1.0 m 和 2.0 m × 2.0 m）种植在透水和不透水路面上。分开）。叶芽和衰老过程的开始和结束日期分别记录在2015年春季和秋季。结果表明，与非铺装土地相比，铺装土地的叶片发芽和衰老显着提前。路面下的白蜡树和枫树的全叶发芽日期分别比非路面早 0.7-9.3 天和 0.3-2.3 天。随着树距的增大，叶芽提前天数变长。我们的结果清楚地表明，叶子物候期的改变是由土地铺装造成的，在城市规划和城市植物管理中应考虑到这一点。
It has been widely reported that the urban environment alters leaf and flowering phenophases; however, it remains unclear if land pavement is correlated with these alterations. In this paper, two popular deciduous urban trees in northern China, ash (Fraxinus chinensis) and maple (Acer truncatum), were planted in pervious and impervious pavements at three spacings (0.5 m × 0.5 m, 1.0 m × 1.0 m, and 2.0 m × 2.0 m apart). The beginning and end dates of the processes of leaf budburst and senescence were recorded in spring and fall of 2015, respectively. The results show that leaf budburst and senescence were significantly advanced in pavement compared to non-pavement lands. The date of full leaf budburst was earlier by 0.7–9.3 days for ash and by 0.3–2.3 days for maple under pavements than non-pavements, respectively. As tree spacing increases, the advanced days of leaf budburst became longer. Our results clearly indicate that alteration of leaf phenophases is attributed to land pavement, which should be taken into consideration in urban planning and urban plant management.
