摘要:对竹木混交林和改为毛竹纯林后处于不同经营时期的林地土壤肥力变化进行了调查分析。研究结果表明,竹木混交林土壤的自然肥力均高于相近地段上相同立地条件的毛竹纯林。毛竹纯林随经营期的延长,其土壤的自然肥力呈下降趋势,这是毛竹纯林的生长特性和经营方式决定的。在改为纯林经营后的第一个10a中,林分土壤肥力指标下降十分显著,下降速率高于第二个10a,在纯林经营的不同时期,各肥力指标变化速率不一致。毛竹林鞭根系对竹林土壤孔隙度有明显的影响。
Soil fertility analyses in a mixed bamboo forest and two pure bamboo forests transformed at different growth stages from mixed stands at various times had been done and the results showed the natural soil fertility in a mixed bamboo stand was better than those in pure bamboo stands in the neighbouring sites after a longterm management.As the management term of pure bamboo stands prolonged the natural soil fertility declined,which resulted from the growth characteristics of pure bamboo forest and the management methods. The soil fertility in pure bamboo stands declined faster in the first 10 years than that in the second 10 years after they were transformed from mixed forest with trees.The fertility index varied at different rate during the period. The rhizomes and root of bamboo affect the soil porosity obviously.
