甘肃插岗梁自然保护区苔藓植物与针叶林更新关系研究

Study on Updating Relations between Bryophytes and Coniferous Forest in Chagangliang Nature Reserve of Gansu

寒温性针叶林是甘肃插岗梁自然保护区内的主要森林植被,苔藓资源十分丰富,形成了苔藓云杉冷杉林以及草类、箭竹云杉冷杉林等丰富多样的林型。以苔藓林分和非苔藓林分为对比,研究了苔藓植物对保护区内寒温性针叶林林木更新的影响。通过对林木萌发质量及数量、土壤含水量、土壤类型、腐殖质、枯枝落叶层有机质含量的调查分析发现,藓类林分相比非藓类林分而言,更有利于树木的生长和更新。

The cold-temperate coniferous forest is main forest vegetation in Chagangliang Nature Reserve of Gan-su,resource of bryophytes is abundant,and forming varieties of forest types including bryophytes spruce fir forest and grass,arrow bamboo spruce fir and so on.Compared forest stand of bryophytes and forest stand of non-bryophytes,the study was conducted on the effect of bryophytes on wood updating of the cold-temperate coniferous forest in Nature Re-serve,Through survey analysis of germination quality and quantity of forest stands,soil moisture,soil type,humus,or-ganic matter content of litter,the results showed that moss forest stands were more conducive to growth and regeneration of trees than non-moss forest stands.
