上海城市森林林下外来入侵植物分布特征
Distribution Characteristics of Invasive Alien Plants under Urban Forest in Shanghai
摘要
Abstract
[Objective]To clarify the species and distribution pattern of invasive alien plants under urban forest in Shanghai,and to promote the healthy development of forest.[Method]A total of 610 herbaceous plots were selected from 122 woodlands in Shanghai from June to September 2022,to investigate and analyze the herbaceous communities in Shanghai's urban forests.[Result]There are 179 species of herbaceous plants in the urban forest ecosystem in Shanghai,belonging to 127 genera in 51 families.Among them,43 species are invasive alien plants,accounting for 24.02%of the total species,and 136 species are native plants,accounting for 75.98%.The alien plants in Shanghai urban forest have generally high degree of invasion,and the majority of woodland has more than 60%of the area invaded.Solidago canadensis,Erigeron philadelphicus,E.sumatrensis and Alternanthera philoxeroides are the plants with the highest frequency and importance value in terms of invasion,which dominate plant communities with a strong competition for resources.Chongming Island,Changxing Island,Baoshan District,Jiading District,Jinshan District,southern Fengxian and northern Pudong New Area,mostly in the outer suburbs of the city,are where the most invasions occur.[Conclusion]The invasion degree of alien plants in Shanghai urban forest is generally high.In the future,it is necessary to identify the plant for which the prevention and control measures should be taken according to the degree of harm,select suitable tree species to create a multi-species and multi-layer stand structure,and adopt multiple targeted options such as mowing and ploughing to prevent and control invasive alien plants.关键词
