摘要
通过对定海松林及更新层的调查，发现多数松林在皆伐后演替为落叶阔叶林，少数为常绿落叶阔叶林和灌、草丛。更新树种共计34种，占优势的仅9种，且多为落叶阔叶树种。针对演替类型及更新树种存在单调贫乏的现状，结合海岛具体实际，提出封山育林、人工造林和树种选择的方向性建议，将为松村线虫病除治迹地的更新改造提供依据。
Investigations of regeneration storey of pine forest in Dinghai, Zhejiang province demonstrated that succession species after clear cut was mostly deciduous broad-leaf forest with few evergreen broad-leaf forest and shrub, even some hassock. There were 34 succession species, 9 deminant, mostly deciduous broad-leaf species. Proposals like closing hillside to facilitate afforestation, artificial forestation and species selection were made for regeneration of Bursaphelenchus xylophilus deseased pine forest.
