Major effects of road construction on eco-environment

Abstract

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.
