Abstract:The forest, mainly masson pines (Pinus massoniana Lamb) in Nanshan, Chongqing has exhibited decline since the beginning of the 1980's.According to the results of the diagnosis of injury symptoms, the determination of sulfur and fluorine contents of leaves and the monitoring of the atmospheric S02 and fluoride in the area, it may be concluded that the air pollution by SO2 and fluoride is the major cause of the decline of the forest. The contributions by acid rain, acid fog and pests to the decline were discussed as well.
Keywords:masson pine  forest decline  air pollution  SO_2  fluoride
