Taiwania flousiana plantations with different stand ages (9-, 14-and 20-year-old) in Nandan Shankou Forest Farm of Guangxi were selected to study the soil physical and chemical properties and enzyme activities by spacial-temporal exchange method. The results showed that there existed differences in the soil physical and chemical properties and enzyme activities among the 3 age classes of T. flousiana plantations. The surface soil(0-20 cm)density, total porosity and maximum moisture capacity were 0.978 g·cm-3, 63.10% and 64.55% in 8-year-old T. flousiana plantation; 0.914 g·cm-3, 65.53% and 71.70% in 14-year-old T. flousiana plantation; and 0.890 g·cm-3, 66.40% and 74.58 in 20-year-old T. flousiana plantation. With the increase of stand age, the changes of soil chemical and biochemical indicators were not the same, but to 20-year-old forest period, most soil nutrient and enzyme activity index increased, the soil fertility conditions improved.

Abstract: Taiwania flousiana plantations with different stand ages (9-, 14-and 20-year-old) in Nandan Shankou Forest Farm of Guangxi were selected to study the soil physical and chemical properties and enzyme activities by spacial-temporal exchange method. The results showed that there existed differences in the soil physical and chemical properties and enzyme activities among the 3 age classes of T. flousiana plantations. The surface soil(0-20 cm)density, total porosity and maximum moisture capacity were 0.978 g·cm-3, 63.10% and 64.55% in 8-year-old T. flousiana plantation; 0.914 g·cm-3, 65.53% and 71.70% in 14-year-old T. flousiana plantation; and 0.890 g·cm-3, 66.40% and 74.58 in 20-year-old T. flousiana plantation. With the increase of stand age, the changes of soil chemical and biochemical indicators were not the same, but to 20-year-old forest period, most soil nutrient and enzyme activity index increased, the soil fertility conditions improved.
