摘要: 公路已成为全球景观中一种重要的景观类型,其里程和密度在逐年增加。公路建设项目,尤其是公路网络的形成不仅减少了自然生境的数量,而且严重降低了自然生境的质量。公路建设对生态环境造成的影响主要包括生境损失、生态干扰、公路致死、阻碍作用、廊道效应以及公路网络造成的严重生境破碎化。缓解公路生态影响的措施有避免、消减和补偿3种。

Abstract: Road is an important type of global landscapes,and its length and density is increasing year after year.The quantity and quality of natural habitats are decreased and worsened by road infrastructures and road networks.The major ecological effects of road construction on eco-environment include habitat loss,eco-disturbance,barrier effects,corridor effects,and serious habitat fragmentation induced by road networks.Three countermeasures were put forward to mitigate the habitat fragmentation by road infrastructure.

Key words: Tripterygium wilfordii, endophytic bacteria, growth-promotion, secondary metabolism, triptolide.
