摘要: 对天然更新米槠林、人工促进更新米槠林、杉木幼林和杉木中龄林等林地土壤的孔隙组成和养分状况作了研究分析。结果表明:与天然更新米槠林相比, 人工促进更新米槠林、杉木幼林和杉木中龄林林地的土壤总孔隙度、非毛管孔隙度、自然含水率和通气度均下降,容重增大, 土壤结构性变差, 通气性和渗透性减弱, 土壤蓄水能力下降, 土壤有机质、全量养分、速效养分和pH 值均减少, 土壤的保肥供肥能力变差, 土壤肥力下降。这说明自然更新米槠林更少受到人为干扰, 枯落物数量和质量均优于其他林分, 有利于养分的贮存和转化, 对土壤肥力的保持作用更明显。表2 参10

Abstract: Soil pore space composition and nutrient status under natural formation of Castanopsis carlesii community , artificial forcing regeneration Castanopsis carlesii community , young Chinese fir plantation and halfmature Chinese fir plantation were studied .The results indicated that , compared to natural formation of Castanopsis carlesii community , the soil total porosity , non-capillary porosity , natural water percentage and air permeability of artificial forcing regeneration Castanopsis carlesii community , Chinese fir plantation and halfmature Chinese fir plantation were decreasing , but soil volume weight was increasing , soil structural property was weak , air permeability and water permeability were decreasing , soil water-storage ability was weak , soil organic matter , total nutrient , available nutrient and soil pH were decreasing , and soil capacity of nutrient supplying and storage was decreasing .It concluded that natural formation of Castanopsis carlesii community was worse influenced by human being , and the quantity and quality of treelitter were better than other forest stands , which benefits storage and convertion of nutrient .It was obvious that Castanopsis carlesii community maintained greatly soil fertility .
