摘要
根据野外调查,探讨了广西桉树人工林外来入侵植物的种类组成、生长型、危害程度和生活史对策。结果表明:桉树人工林内现有外来入侵植物12科26属30种,种数最多为菊科植物,有13种,占总种数43.3%,生活型组成以草本植物为主,共有23种,占总物种数76.7%;危害状况严重的有7种。改变林地清理方式、适当人工清理和加强监控管理是控制入侵植物危害的有效途径。
Based on the field investigation,the species composition,growth type,damage degree and life history strategy of alien invasive in Eucalyptus spp. plantations in Guangxi area were discussed.The results showed that ,the existing invasive plants in Eucalyptus spp. plantation were 12 families and 26 genera and 30 species,and most species was 13 species in compositae plant,accounted for 43.3%.The life type dominated by herbaceous plants form a total of 23 species, accounted for 76.7% of the total number of species.Change the ground clearance, the appropriate manual cleaning and strengthen monitoring and management is the effective way to control invasive plant hazards.
