摘 要：
对海南儋州两种经营方式下桉树林与人工椰林样地连续定点采样,分析不同经营方式下林地土壤的物理性状差异。结果表明:(1)短伐桉树林、椰林土壤表层的0~10 cm粒级组成"粗化"明显,而非短伐桉树林的变化较小;(2)短伐桉树林、非短伐桉树林、椰林表层0~10cm的土壤容重分别为1.65,1.69,1.56 g·cm-3,较其他林地要大;(3)短伐桉树林、非短伐桉树林和椰林的土壤毛管孔隙度非常接近,约为33%,而非毛管孔隙度分别为8.66%,4.95%,5.99%,总孔隙度分别为41.89%,38.62%,39.05%;(4)短伐桉树林、非短伐桉树林、椰林的土壤紧实度随着深度增加而增加,非短伐桉树林的土壤紧实度明显高于短伐桉树林和椰林,而短伐林与椰林的土壤紧实度相近。

摘 要：
Two Eucalyptus plantations and one Cocos plantation were chosen as study sample plots in Danzhou Forest Farm, which lies in west Hainan Island. Through monitoring and sampling in the fixed sites, differences in soil physical properties of plantations managed in different ways were analyzed. The results showed that:(1) Soil separates were obviously "coarsening" in 0 ~10 cm soil layer of short-rotation Eucalyptus plantation and Cocos plantation, and the change was little in the layer of non-short-rotation Eucalyptus plantation;(2) The soil bulk densities in 0~10 cm soil layer of short-rotation Eucalyptus plantation, non-short-rotation Eucalyptus plantation and Cocos plantation were 1.65, 1.69 and 1.56 g·cm-3respectively, which were higher than other woodlands;(3)Capillary porosity was almost equal of short-rotation Eucalyptus plantation, non-short-rotation Eucalyptus plantation and Cocos plantation, about 33%. Non-capillary porosity was 8.66%, 4.95% and 5.99% and total porosity, 41.89%, 38.62%, 39.05%, respectively;(4) The compaction of non-short-rotation Eucalyptus plantation was obviously higher than short-rotation Eucalyptus plantation and Cocos plantation, and the values of which were very similar.
