自然演替15年的亚热带人工混交林物种多样性与群落结构恢复特征
Recovery Characteristics of Species Diversity and Community Structure in Subtropical Mixed Plantations after 15 Years of Natural Succession
摘要
Abstract
The resilience of species diversity and community structure are important indicators to judge the success of mixed plantation construction.This study was conducted in the subtropical mixed plantations formed after the renovation of pure forest of Cunninghamia lanceolata in 2005 in Yunyong forest farm,Foshan City,Guangdong Province.Recovery characteristics of species diversity and community structure were analyzed based on the 6.48 hm2 plot which was set up in the typical areas of the above plantations in 2020.The results were as follows:(1)169 woody plant species belonging to 121 genera in 55 families colonized the community after 15 years of natural restoration,indicating the subtropical mixed plantations had a strong conservation ability of species diversity.(2)Seven of the top ten species in terms of importance value were artificially introduced species,indicating that early introduced species still had an important effect on the community structure of subtropical mixed plantations after 15 years of natural succession.(3)The average diameter at breast height(DBH)of all individuals was 8.60 cm,and the DBH distribution was an inverse-J shape,indicating the community had normal regeneration ability.(4)Early artificially introduced species could also have normal regeneration ability,although their DBH shapes mainly showed a bell curve due to the short recovery time.The results revealed the subtropical mixed plantations had strong conservation ability of species diversity and community structure.These findings could provide a theoretical basis for optimizing forest restoration strategies in subtropical areas.关键词
