图3 夜间灯光对外来入侵植物和本地植物平均株高和相对盖度的影响。无路灯表示无路灯直接照射区域, 有路灯(不亮)表示该区域有路灯灯杆但是路灯不亮, 有路灯(亮)表示该区域有路灯灯杆且路灯正常亮。图中数据为平均值 ± 标准误。不同字母表示同一指标在不同夜间灯光水平间差异显著(P < 0.05)。左上角的回归图展示了外来入侵植物或本地植物的生长指标与夜间灯光强度的关系。在显著以及边际显著关系的模型中展示了模型的R2、P值和回归拟合线。

Fig. 3 The impacts of artificial light at night on the average plant height and relative cover of invasive alien plants and native plants. The areas lacking direct illumination from streetlights (NO POLES). The areas where streetlights on poles are not lit (UNLIT POLES). The areas where streetlights on poles are lit (LIT POLES). The values are the mean ± SE. Different letters indicate significant differences in the same index among different levels of artificial light at night (P < 0.05). The regression plots in the upper left corner illustrate the relationships between the growth indices of invasive alien plants or native plants and the intensity of artificial light at night. For models showing significant and marginally significant relationships, the R², P values, and regression fit lines are displayed.
