| 摘 要： | 森林的不同更新方式对森林土壤理化性质有重要影响．本研究通过野外调查探讨中亚热带山区杉木人工林和米槠人促更新林2种不同更新方式下林地土壤理化性质的变化特征，并用土壤退化指数定量描述土壤质量变化．结果表明：杉木人工林土壤表层（0—10cm）容重显著高于米槠人促更新林（P〈0．05）；随土壤深度的增加，杉木人工林和米槠人促更新林土壤有机C、全N、全P、水解N和有效P均逐渐降低．米槠人促更新林表层（0—10cm）土壤有机c比杉木人工林高出15．6％，全N、全P以及水解N和速效P也均表现出人促米槠更新林高于杉木人工林的趋势；土壤退化指数的计算结果表明杉木林土壤质量显著低于米槠人促更新林．

| Abstract: | Through field investigation and laboratory analysis, the soil physical and chemical properties were compared between Cunninghamia lanceolata and Castanopsis carlesii plantations under two different reforestation treatments in mid-subtropical mountainous area in the South of China. The resuits showed that the soil bulk density in the surface （0 - 10 cm） of Chinese fir plantation was significantly higher than that in the CastaNopsis carlesii plantation （P 〈 0. 05 ） ; the soil organic carbon content （SOC）, total N and P, hydrolysable N and available P in both plantations decreased generally with soil depth; the surface （0 -10 cm） SOC of Castanopsis carlesii was 15.6% higher than that of Chinese fir plantation, and the total N and P, hydrolysable N and available P of Castanopsis carlesii were higher than those of Chinese fir. In addition, the soil degradation index showed that the soil quality in Chinese fir plantation was poorer than in Castanopsis carlesii plantation. |
