摘要

近年来

外来入侵植物逐渐增多

对生态构成了一定的威胁。为查清高速公路中出现的外来入侵植物对当地生态系统的影响程度

采用实地调查的方法

对河南省高速公路边坡的植被进行了德式多度制统计

共调查植物58种。发现已有外来入侵植物4种

有些入侵植物如加拿大蓬的入侵情况已经比较严重

而有些人工种植植物如波斯菊由于不适应野外环境而频临灭绝。针对以上问题

提出了高速公路边坡入侵植物的防治建议

即加大人工防治的力度

缩短边坡植被恢复时间

慎选观赏植物

加强入侵植物研究等。

Abstract

Increased exotic plant invasion has a great effect on ecology

especially on highway side-slope. In order to find out the influence degree of exotic plant invasion on local ecosystem

statistics are made for vege-tation on highway side-slope in He′nan Province by field investigation methods. 58 plant species are investi-gated totally. 4 kinds of exotic plant invasion are identified

of which some invades the region heavily

such as Conyza canadensis. However

some artificial plants are facing extinction due to inadaptable field environ-ment

such as Cosmos bipinnata. For above problems

control suggestions are proposed

such as taking arti-ficial control

shortening the time of vegetation restoration on side-slope

selecting ornamental plants critical-ly

and enhancing the research on exotic plant invasion.
