In degraded red soil area

taking the Pinus massoniana forest mixed by shrub and grass measures with 4 different management years as the object of study

and the unmanaged severely degraded pine as control

the effects of management years on soil nutrients were studied. The results showed that: (1) The range of soil organic matter

total nitrogen and total phosphorus contents were 0.81～28.10 g/kg

0.18～1.15 g/kg and 0.03～0.18 g/kg

respectively

and all contents increased with the increase of management duration

and first fast and then slow in increasing rates. Total potassium contents ranged in 0.92～4.65 g/kg

with the highest in the 40—60 cm soil layer after managed for 13 years

the increasing rate was first slow then fast. (2) There was a correlation between soil nutrient content and management years: management years gave a significant correlation with soil organic matter and total N contents（P＜0.05）

and a highly significant correlation with total P（P＜0.01）. But no correlation was observed between soil total K content and management years. These findings suggested that the soil nutrient contents of Pinus massoniana forest soil was related to the management years

and provided scientific basis for ecological management and restoration.
