摘　　要：研究滨海沙地不同竹林土壤理化性质差异并评价土壤质量,旨在充分了解滨海沙地竹林防护林土壤肥力状况,指导滨海沙地竹林防护林建设和经营。在福建省东山县赤山国有防护林场选取8种滨海沙地适生竹林,分别测定各竹林0~20 cm土层土壤理化性质;采用单因素方差分析对各项指标进行显著性检验,运用主成分分析、加权综合指数法和模糊数学法,对不同竹林土壤肥力质量进行综合评价。四季竹(Oligostachyum lubricum)的土壤含水率、土壤密度、毛管孔隙度、非毛管孔隙度、土壤总孔隙度等物理性质指标与其他竹林对应物理性质指标皆存在显著性差异(P<0.05)。土壤pH平均变化范围为5.01~7.36,除绿竹(Bambusa oldhamii)土壤pH偏中性外,其他竹林土壤pH呈弱酸性,且均不存在显著性差异(P>0.05)。土壤有机质平均变化范围为4.43~11.06 g/kg,福建茶秆竹(Pseudosasa amabilis var.convexa)有机质含量显著低于其他竹林。土壤全钾和速效钾平均变化范围分别为4.59~79.33 g/kg和0.78~43.11 mg/kg,土壤全氮和全磷平均变化范围分别为0.47~2.42 g/kg和0.09~0.37 g/kg,土壤电导率,氮、磷、钾全效及速效等养分指标在不同竹林间存在显著性差异(P<0.05)。8种竹林土壤质量由高到底依次为:矢竹(Pseudosasa japonica)>四季竹>实肚竹(Phyllostachys nidularia f.farcata)>绿竹>花吊丝竹(Dendrocalamus minor var.amoenus)>鼓节竹(Bambusa tuldoides‘Swollenintrnode’)>青丝黄竹(Bambusa eutuldoides var.viridi-vittata)>福建茶秆竹。滨海沙地竹林防护林土壤理化性质和总体质量均受竹林类型的显著影响,矢竹林能有效改善土壤质量,福建茶秆竹林对土壤的改善作用不明显,滨海沙地竹林防护林建设经营应合理选择竹种和种植方式。In order to determine the quality of soil fertility of bamboo species in coastal sandy land and guide the construction and management of bamboo shelter forest in coastal sandy land,the difference of soil physical and chemical properties of different bamboo forests in coastal sandy land and evaluate the soil quality were studied.Eight bamboo species in coastal sandy land were selected from Chishan State-owned Farm in Dongshan County,Fujian Province.The physical and chemical properties of the 0-20 cm soil layer of each bamboo species were determined.One-way ANOVA analysis was conducted to test the significance of each index,and principal component analysis weighted comprehensive index method and fuzzy mathematics were used to comprehensively evaluate the soil fertility quality of different bamboo species.Soil moisture content,soil density,capillary porosity,non-capillary porosity and total soil porosity of Oligostachyum lubricum were significantly different from those of other bamboo forest(P<0.05).The average pH of soil ranged from 5.01 to 7.36,and there was no significant difference in the pH of other bamboo forests except the neutral soil pH of Bambusa oldhamii(P>0.05).The average soil organic from 4.43-11.06 g/kg,Pseudosasa amabilis var.convexa was significantly lower than that of other bamboo forests.The average range of soil total potassium and available potassium was 4.59-79.33 g/kg and 0.78-43.11 mg/kg.The average range of soil total nitrogen and total phosphorus was 0.47-2.42 g/kg and 0.09-0.37 g/kg,and soil electrical conductivity,total availability and quick availability of N,P,K.had significant differences among different bamboo forests(P<0.05).The order of soil fertility quality index order of the eight bamboo species was P.japonica>O.lubricum>Phyllostachys nidularia f.farcata>B.oldhamii>Dendrocalamus minor var.amoenus>B.tuldoides‘Swollenintrnode’>B.eutuldoides var.viridi-vittata>P.amabilis var.convexa.The physical and chemical properties and total soil quality of bamboo shelterbelt in coastal sand
