公路是一个人工干扰廊道,其边坡的植被受其影响具有明显的边缘效应。但与其他区域的边缘效应不同,它的植物物种并不是最丰富的区域,相反受公路小气候条件影响,其风速大、污染重、温度高,而且N元素可以得到不断的补充,这与其他自然原因造成的边缘效应明显不同,本研究仔细调查了多条不同路龄的公路边坡植被,分析公路边坡边缘植被的特点,为将来进行公路边坡植被恢复提供理论依据。 Road is a man-made disturbance corridor, the vegetation on the slope affected by it has obvious edge effect. However, its marginal effect is different from that of other regions. Its plant species are not the most abundant regions. On the contrary, it is affected by the microclimate of the highway. Its wind speed is heavy, the pollution is heavy and the temperature is high. Moreover, the N element can be constantly replenished, The reason is that the marginal effects are obviously different. In this study, we carefully investigated the vegetation of roadsides with different road age and analyzed the characteristics of the vegetation on the edge of the roadsides for providing theoretical basis for the future vegetation restoration of highway slopes.
