探讨了对针阔混交林过伐林种子更新的动态,通过对样地乔木树种的种子库、枯枝落叶层的种子库以及土壤种子库与当年生幼苗的关系得出:在自然条件下,各树种的种子库中种子转化为幼苗的比率极低,一般在0.0055%—0.5000%之间。同时,分析并强调了枯枝落叶层在种子库动态中以及在森林更新中的生态学意义。并且,结合植被动态演替和现有林的经营提出了“潜接层”概念。 The dynamics of over-deforestation seed regeneration in coniferous-broad-leaved mixed forest was discussed. The relationship between the seed bank of seed bank, litter layer and soil seed bank in the sample tree was studied. The results showed that under the natural conditions, Seed in each species of seed bank into the seedling ratio is very low, usually between 0.0055% -0.5000%. At the same time, the ecological significance of litter layer in seed bank dynamics and in forest renewal was analyzed and emphasized. And, combined with the dynamic succession of vegetation and the management of the existing forest, we put forward the concept of “latent layer”.
