摘要
对肇庆市北岭山23种10 a生乡土树种及造林地进行调查。结果表明:红锥(Castanopsis hystrix)、黧蒴(Castanopsis fissa)、红荷木(Schima wallichii)、西南桦(Betula alnoides)生长表现最好,树高和冠幅生长较快,林分形成较好的森林环境;火力楠(Machilus macclurei)、木荷(Schima superba)、樟树(Cinnamomum camphora)、仪花(Lysidice rhodostegia)、白锥(Castanopsis fabri)、蒲桃(Syzygium jambos)、毛栗(Castanea henryi)生长次之;潺槁(Litsea glutinosa)、海南红豆(Ormosia pinnata)、阴香(Cinnamomum burmanii)、鸭脚木(Schefflera heptaphylla)、水翁(Cleistocalyx operculatus)、铁冬青(Ilex rotunda)、扁桃(Mangifera perciliformis)和猫尾木(Dolichandrone cauda-felina)生长表现一般;尖叶杜英(Elaeocarpus apiculatus)、蕊木(Kopsia arborea)、幌伞枫(Heteropanax fragrans)和秋枫(Bischofia javanica)等生长表现较差。混交造林的乔木层、灌木层、草本层的物种丰富度指数、多样性指数和均匀度指数均高于木荷林;混交造林枯落物厚度、枯落物储量、最大持水率和最大持水量也均大于木荷林;混交造林不同土层的全氮、全磷、全钾、有效氮、有效磷和有效钾含量均高于木荷林。乡土树种混交种植的森林生态效益明显优于单一树种的木荷林。
The growth of23broad-leaved trees species in the10-year-old plantation at Zhaoqing Beiling mountain was investigated.With their fast growth in height and crown surface,and better performance in forming forest,all investigated tree species,Betula alnoides,Castanopsis hystrix,Castanopsis fissa,Schima wallichii were considered the best.Machilus macclurei,Schima superba,Cinnamomum camphora,Lysidice rhodostegia,Castanopsis fabri,Syzygium jambos and Castanea henryi formed a group with medium rapid growth,Litsea glutinosa,Ormosia pinnata,Cinnamomum burmanii,Schefflera heptaphylla,Cleistocalyx operculatus,Ilex rotunda,Mangifera perciliformis,Dolichandrone cauda-felina formed another group with medium slow growth,Elaeocarpus apiculatus,Kopsia arborea,Heteropanax fragrans,Bischofia javanica with slowly growth.The richness index,diversified index,evenness index of the mixed afforested stand'tree layer,shrub layer and herb layer were higher than the Schima superba stand.The same results appeared in the data of thickness,litterstanding crop,maximum water absorption rate of litter and maximum water holding capacity of litter.The soil nutrients of mixed afforested stands were also higher than single afforested ones.The forest eco-efficiency of mixed afforestation of indigenous tree species were obviously superior to those of the single Schima superba stand.
