Abstract: The status of soil nutrient in the southern forest ecosystem of China was synthetically studied. The main results showed that different forests had different effects on the status of soil organic matter and nutrient. Broad-leaved forest could accumulate organic matter and improve the nutrient status of soil. The forest of Pinus massoniana had active effects on available nutrient (nitrogen,phosphorus and potassium) of the soil,especially on available phosphorus. Cunninghamia lanceolata could not help improve the nutrient status,chemical and physical properties of the soil,while the forest mixed with conifer and broadleaf tree could improve the status of soil nutrient,especially for available micronutrient of soil,so the properly mixed forest was advantageous to the continued development of forestry. In addition it was found that the content of available micronutrient in the rhizosphere was higher in the early spring than that at other time,which could supply a need for the trees in growing season. So the supply of soil micronutrient in forest was scarcely insufficient.
