| 摘 要： | 对1代杉木人工林皆伐后,采用不同更新方式形成的14年生人工更新杉木林和14年生天然更新杉阔混交林进行了研究,探讨不同更新方式对杉木林地土壤肥力的影响。通过对不同更新方式林地土壤理化性质的分析测定,结果表明:不同更新方式对林地土壤物理和化学性质均有影响。天然更新林地0-20 cm和20-40 cm土层土壤容重分别比人工更新林地低1.73%和1.69%,毛管孔隙度分别高31.75%和30.99%;天然更新林地土壤各水分含量指标均有不同程度的提高;天然更新林地0-20 cm和20-40 cm土层土壤pH值分别比人工更新林地高0.16和0.14,有机质分别高24.15%和30.66%,全N含量分别高21.99%和21.63%,全P含量分别高44.94%和65.28%。与人工更新相比,天然更新更有利于林地土壤肥力的恢复和维持。

| Abstract: | Regenerated Chinese fir plantations by different regeneration patterns after clear cutting(14 year-old artificial regeneration forest,14 year-old Chinese fir and broad leaved natural regeneration forest) were selected as the research object,and the effects of different regeneration patterns on the second-generation Chinese fir plantation soil fertility were detected.Through analytic determination on soil physico-chemical properties in different woodlands,the result indicated that different regeneration patt... |
