摘要
[目的]探究不同模式红椎及马尾松人工林自然更新状况。[方法]对环江县华山林场4种林分(红椎纯林、马尾松纯林、红椎与马尾松同龄混交林、红椎与马尾松异龄混交林)建立固定幼苗样方,进行林下幼苗更新研究。[结果]乔木层中自然更新情况一般,主要表现为物种数、个体数稀少;灌木层中的乔木树种的个体大部分为人工林目标树种的幼树,自然更新的乔木幼树在各林分中所占比例很低。[结论]结果为红椎、马尾松人工林林下更新研究提供了科学依据。
[Objective]To explore the natural regeneration status of different models of Castanopsis hystrix and Pinus massoniana plantations.[Method]Fixed seedling quadrats were established to study the regeneration of undergrowth seedlings in four stands(Castanopsis hystrix pure forest,Pinus massoniana pure forest,Castanopsis hystrix and Pinus massoniana mixed forest of the same age,Castanopsis hystrix and Pinus massoniana mixed forest of different age)in Huashan forest farm of Huanjiang County.[Result]Tree layer had a general regeneration,mainly as the low level of individual number and species number;Most saplings of tree species on the shrub layer were the saplings of plantation species.Saplings of natural regeneration trees had the low proportion in each forest.[Conclusion]The results provide a scientific basis for the study of understory regeneration of Castanopsis hystrix and Pinus massoniana plantations.
