Abstract:The effect of atmosphere pollution on forest growth and soil characteristics was investigated in Pearl River Delta of China from 1998 to 1999. The preliminary results showed that the atmosphere contaminator mainly contained SO\-2, NO\-\%x\% and suspended granule. Which caused large area acid rain with high frequency. As pollution became more serious, there were decreases in pH value and increases in the content of SO\ \{2-\}\-4 and Al\ \{3 \} in forest soil; the chlorophyll concentration also would decrease both in \%Pinus massoniana\% Lamb. and\% Pinus elliottii\% Engelm., and their growth declined, even died. But their sensitivity of atmosphere pollution varied in species. Compared with \%Pinus massoniana\% Lamb., planting with \?acia mangium\% Willd. Would increased the land buffer capability relatively and improved soil fertility preferably.
Keywords:atmosphere Pollution  growth of forest  characteristic of soil  Pearl River Delta
