摘要
为查清河南省高速公路沿线外来入侵植物种类组成以及高速公路边坡生态恢复过程中对护坡植被的影响程度,采用植物群落野外调查方法对河南省高速公路典型边坡植被进行了统计和研究,结果表明:研究路段共有植物60种,隶属于25科,55属。其中本地入侵植物30种、外来入侵植物12种,入侵途径主要包括人为有意引入、人类活动无意引入和自然侵入;据建立的河南省高速公路外来入侵植物危害风险评价指标分析:在12种外来入侵植物中,其中有4种属于高风险危害植物,5种属于中风险危害植物,3种尚未构成危害。因此,应该密切关注高速公路沿线外来植物入侵问题,并采取相应的措施进行有效控制。
In order to figure out the species of invasive plans and in the process of ecological restoration of expressway in Henan Province, it has some degree of influence to slope protection plantation, the field investigation of plant community is used to gather statistics and study the typical slope vegetation of expre ssway in Henan Province. The conclusion can be shown as： this research studied 60 species in one section of expressway, and they are belongs to 25 families, 55 genera. And there are 30 local invasive plants, 12 alien invasive plans in that. The invasion pathways include contrived intentional introduction, unintention- al introduction of human activity and natural ialien invasive plants＇ hazard of Henan expressway. In the 12 alien invasive plans, there are 4 species belong to high hazard plants, 5 species are middle hazard plants and 3 species have not constitute a hazard yet. Therefore, we should pay close attention to the problem of invasive plant of expressway, and take measures to control it effectively.
