Abstract: The paper reviewed the plant resistance mechanisms under lead stress from physiological and biochemical aspects,e.g.,cell division,permeability of plant membrane,photosynthesis,antioxidative enzymes system,etc.,and discussed the relationships of plant resistance with Pb2+ transportation across membranes,root exudates,metal cheaters,and Pb2+ distribution in plants.

Key words: the least cost path method, species distribution models, GIS, phylogeography, Quaternary, Pedicularis longiflora.
