摘要
植被护坡是公路边坡防护的有效途径,为探讨黄土高原地区植被恢复效果,为道路边坡恢复与重建提供理论与技术依据,依托高速公路建设工程,遵循恢复生态学原理,研究了高速公路边坡植被恢复的生态效果。结果表明:植被护坡中,理想植物群落设计组合应该是草-灌混合群落;豆科植物在群落中所占比例是评价护坡群落生态效益的重要指标;护坡植被覆盖度控制在合理范围内,有利于本土植被侵入和群落演替;护坡群落由人工群落向自然群落演替是一个动态、长期的过程。
Revegetation on side slope was an effective way for the highway side slope protection. On support of highway constructmg project and principle of restoration ecology, this paper studied the ecological effects of vegetation restoration in highway slope protection on loess plateau. The research can provide theoretical and technique supports to highway slope restoration. The results showed that: In revegetation project, the ideal community combination should be grass-shrub mixed community. The percentage of leguminous plant was a significant index for evaluating the ecological benefit in a slope community. The vegetation fractional coverage should be controlled in a reasonable range which was favor of native vegetation invasion and community succession. It was a dynamic and long-term process for the slope communities to change from artificial to natural communities.
