Abstract: The coniferous forest in the subtropical zone of China is suffering from very severe decline. The paper studied the declining pattern of polluted P. massoniana stand in terms of stand characters ,tree growth, physiological properties and contents of nutrients such as nitrogen, phosphorus and potassium of the needles. The results indicated that the number of chlorotic individuals increased with air pollution. The weight of needles and the number of corns per tree in the polluted site respectively, the contents of chlorophyll and nutritive elements of the needles in the polluted sites were lower than in the non-polluted site. In addition, the growth values of the height, diameter and volume of the pine in the polluted sites were lower than those of pine in the non-polluted site.
