摘要:炼山是中国南方人工林经营过程中处理采伐剩余物的常用手段。 但近年研究表明炼山会引起土壤养分流
失等负面问题。 为研究炼山林地清理方式对杉木人工林土壤物理化学性质的影响,文章以福建省南平葫芦山国有林
场杉木人工林为研究对象,调查并分析炼山及不炼山 2 种造林方式对土壤物理化学性质的影响。结果表明:炼山能降
低表层土壤容重,改善土壤蓄水保水功能并提高土壤的渗透性能;炼山后土壤表层 pH 值提高,全氮和有机质含量降
低,水解氮、速效钾明显增加。

Abstract: Slash burning is a common way to deal with the cutting residues in the process of plantation man-
agement in South China,but in recent years,research shows that slash burning will cause negative effects such
as soil nutrient loss. In order to study the influence of slash burning on the soil physical and chemical properties
of Chinese fir plantation,this paper takes the Chinese fir plantation of Hulushan state-owned forest farm in
