Abstract: In the leaching process, the concentration or caicium declines, but no remarkable difference has been found with different acid rains. As for the concentration of alumunium, there is no distinct change after leaching with acid rain of pH>3.0, but it's markedly increased after acidic leaching of pH2.5 Consequently, the declination of Ca/Al ratio is the result of leaching process when the pH of acid rain is atove 3.0. Only when pH<2.5, the leaching of acid rain starts to reduce this ratio. The declination speed becomes slower with the intensification of leaching.
Key words: development zone, planning environment impact assessment, land carrying capacity, eco-sensibility, eco-suitability, ecological land use
