宝华山主要植被类型土壤种子库存初探

 落叶常绿阔叶混交林和落叶阔叶林的土壤种子库分别有49种和33种植物，其中，前者有草本42种，灌木3种，乔木4种，密度为255粒／m2；后者有草本29种，灌木1种，乔木3种，密度为145粒／m2。两植被类型的土壤种子库组成与其现存地上植被的组成相似性极小。落叶常绿阔叶混交林林窗的土壤种子库有33个种，密度为413粒／m2，与非林窗区域的土壤种子库组成仅有53.1%的相似性。

A Preliminary Study on the Soil Seed Banks of the Dominant Vegetation Forms on Baohua Mountain

49 species, including 42 herbs, 3 shrubs and 4 trees, and 33 species, including 29 herbs, 1 shrubs and 3 trees were recorded in the soil seed bank of a deciduous & evergreen broad-leaved mixed forest and in that of a deciduous broad-leaved forest respectively. The seed density for the former forest was 255 grains/m2 and that for the latter one was 145 grains/m2. Little similarity between the species composition of the soil seed bank and the aboveground vegetation species composition for both forests could be found. 33 species and 413 grains/m2 were observed in the gap part of the soil seed bank for the former forest type, and the similarity in species composition between the gap soil seed bank and the non-gap one was only 53.1%.
