摘　　要：The species composition and succession discipline after eruption of volcanoes in Wudalianchi Nature Reserve, China, including new volcanoes, such as Huoshao and Laohei Mountains, and old volcanoes, such as East Jiaodebu, Wohu and North Gelaqiu Mountains, in different historical periods were investigated by adopting the concept of space as a substitute for time. The species composition, community characteristics and diversity analysis in the remains of volcanic lava flow at various stages were analyzed. The results showed that 192 types of vascular plants that belonged to 50 families and 126 genera in the survey areas existed in the restoration process of primary succession. At the same time, the agglomeration process of plant community succession and the diversity of dominant community were investigated, and the changes in plant diversity at different succession stages were calculated using Margalef, Simpson, Shannon–Wiener, Pielou, Jaccard and Cody indices.The species composition and succession discipline after eruption of volcanoes in Wudalianchi Nature Reserve, China, including new volcanoes, such as Huoshao and Laohei Mountains, and old volcanoes, such as East Jiaodebu, Wohu and North Gelaqiu Mountains, in different historical periods were investigated by adopting the concept of space as a substitute for time.
