Abstract: The resistant adaptation occurs in plant populations in response to anthropogenic pollution stress. Sensitive genotypes would be eliminated and resistant genotypes would be reserved during pollutant_imposed selection process. As results, pollution_resistant ecotypes evolved. The evolution is obviously of benefit for the plant populations to escape from extinction caused by pollution stress. However, accompanied with the evolution, genetic losses within populations are ecological costs in ecosystem processes. The results of these genetic losses are in great threats to genetic diversity and intergrity of natural systems.
