| 摘 要： | 采用时空互换法,于广西南丹县山口林场选取不同林龄(9、14、20 a)的秃杉人工林作为研究对象,对其土壤物理性质、化学性质和生物化学性质(土壤酶活性)进行研究。结果表明:不同林分年龄土壤性质存在一定的差异,8、14、20 a秃杉人工林表层土壤(0 20 cm)土壤密度分别为0.978、0.914、0.890 g·cm-3,总孔隙度分别为63.10%、65.53 %、66.40%,土壤最大持水量分别为64.55%、71.70%、74.58%。随着林龄的增长,土壤各化学和生物化学指标的变化不尽相同,但林分年龄到20年生时,多数土壤养分和酶活性指标都有所升高,土壤肥力状况得到提高。

| 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. |
