中文摘要	采用幼苗萌发法对广西平果县龙何示范区石漠化山地的土壤种子库进行初步研究.结果表明, 该地区土壤种子库共有108种植物, 隶属于33科81属, 其中草本81种、灌木20种、藤本7种;其土壤种子库的种子密度为 64.6～339.7 粒·m^-2,且在不同土地利用类型区及不同季节存在较大差别.在分析土壤种子库对其植被恢复作用的基础上,认为可采取自然封育和人工造林等措施,以促进现存植被的正向演替.
英文摘要	Soil seed banks had been studied preliminarily with seedling germination in rock desertification mountain land in Longhe Eco-demonstration Area of Pingguo County of Guangxi. The results showed that there were 108 species belonging to 33 families and 81 genera in soil seed banks. These species included 81 herbs, 20 shrubs and 7 vines. Seed densities varied from 64.6 to 339.7 grain·m^-2 in according to different land utilization types and seasons. Based on effect of soil seed banks on vegetation restoration, the befitting measures of vegetation restoration were put forward, which included natural close hillsides and artificial forestation to accelerate positive succession of vegetation.
