摘要:
<正>以江西省泰和县严重退化红壤为研究对象。于1991年采取不同模式重建森林,2001年调查7种不同重建模式的土壤团聚结构及孔隙状况指标,研究森林重建对退化红壤土壤结构特性影响,结果表明:(1)不同模式重建森林对0~40cm土层内团聚结构产生显著影响,阔叶纯林模式的土壤团聚结构优于针阔混交林模式,并且都优于针叶纯林模式;(2)重建森林对土壤孔隙状况也有一定影响,孔隙状况最好的是枫香与湿地松行间混交林地,最差的是湿地松纯林林地;(3)对不同模式重建森林土壤结构稳定性(0~40cm)的综合评价,优劣顺序为:木荷纯林模式>枫香纯林>马尾松×枫香株间混交模式>湿地松×枫香行间混交模式>中等栽植密度晚松纯林模式>湿地松纯林模式>高栽植密度晚松纯林模式。因而可以得出,对于严重退化红壤,在10a内能改善土壤结构的优良森林重建模式是阔叶纯林。
Abstract:
According to the studies on soil structure characteristics of rehabilitated forest in 7 different models in 1991 in Taihe county of Jiangxi province,the results show that:(1)the rehabilitated forest in different models has on obvious effect on soil aggregate structure at the depth of 0~40 cm.The soil aggregate structure of pure broadleaf forest model is the best,that of mixed coniferous and broadleaf forest model comes second,that of pure coniferous is the worst.(2)the rehabilitated forest has some effects on soil pore state.The state of Liquidambar formosana and Pinus elliottii mixed forest model is the best,that of pure Pinus elliottii forest model is the worst.(3)the order of the stability of soil structure of rehabilitated forest is:pure Schima superba forest model>pure Liquidambar formosana forest model>the model of Liquidambar formosana and P.massoniana mixed forest in inter>the model of Liquidambar formosana and P.elliottii mixed forest in line>the model of pure P.serotina Michx forest in middle planting density>the model of pure P.elliottii forest>the model of pure P.serotina Michx forest in high planting density.The good models which can improve the soil structure in 10 years on severely degraded red soil are pure broadleaf forest models.
