为了探讨公路边坡不同生态恢复模式的恢复效果,对北京市延庆县境内的栾赤公路进行了植被调查和土壤性质的实验分析。研究结果表明:人工恢复模式下乔木层群落结构要明显优于自然恢复模式;自然恢复模式下灌木层、草本植物层的物种数量、多样性指数略优于人工恢复模式,而植被盖度小于人工恢复模式;人工恢复模式下的土壤养分状况优于自然恢复模式。在尊重自然生态演替规律的前提下,对公路边坡进行合理的植物种植将有利于边坡植被的恢复。
In order to explore the restoration effect of different ecological restoration patterns on highway slopes, vegetation survey and soil properties of Luanchuan Road in Yanqing County of Beijing were conducted. The results showed that the structure of arbor layer under artificial restoration was obviously better than that of natural restoration. The species number and diversity index of shrub layer and herb layer in natural restoration mode were slightly better than artificial restoration mode, while the vegetation coverage was less than that of artificial Recovery mode; soil nutrient status under artificial recovery mode is better than natural recovery mode. On the premise of respecting the law of natural ecological succession, reasonable planting of roadside slopes will be beneficial to the restoration of slope vegetation.
