Abstract: The overall global-dispersed environmental pollutants,to a certain extent,have been altering natural environment.During industrial revolution,the changing rate,scale and effect ranges are much larger than any other periods among the process of organismic evolution;In the situation of this anthropogenic pollution,organisms in principal would adapt and evolve towards the newly-Renerated environment in stead of the evolutionary model in coordinated development between organisms and physical environment.Rest,arches should be focused on whether today“living beings,having experienced life evolution and passed down gene flow,have the capability to adapt the environment,and how they do it.This paper reviewed plant adaptive effects to pollutants and their differentiation int tolerance.The significance and focal points of research in this area were also discussed.

Key words: halophilic bacteria, ARDRA, diversity, enzyme-producing activity.
