摘要:
为探讨遂昌县次生常绿阔叶林的物种间关系和群落结构,2019年10月,基于9个50 m×50 m样地数据,从物种组成、生态位宽度、生态位重叠和相似性、种间联结角度研究了森林群落15个主要树种的生态位特征和种间关联。结果显示,样地中共有木本植物66种,分属34科53属,主要优势种为甜槠Castanopsis eyrei、杉木Cunninghamia lanceolata和木荷Schima superba;主要物种种对间生态位相似指数>0.6的有88对(83.8%),且生态位重叠指数>0.6的有93对(88.6%);此外,主要物种对总体上呈显著负联结,且正负联结的比值小于1。遂昌县天然次生林已形成以甜槠为建群种的群落,但是群落结构不稳定,种间竞争激烈,优势种之间并未达成动态平衡。基于上述分析结果,遂昌县次生常绿阔叶林的恢复措施,应根据物种间生态位特征和种间联结,搭配补植与甜槠成正联结的树种,为遂昌县森林的经营管理提供理论依据和参考。
Abstract:
In October 2019, 9 sample plots with 50 m×50 m were established in secondary evergreen broad leaf forest in Suichang, Zhejiang province. Investigation was carried out on growth traits of trees and site conditions. The results showed that there were 66 species of woody plants, belonging to 53 genera and 34 families. The dominant species were Castanopsis eyrei, Cunninghamia lanceolata and Schima superba. There were 88 pairs (83.8%) of similarity between the main species and 93 pairs (88.6%) of niche overlap index more than 0.6. In addition, there was a significant negative association among main species, and the positive and negative association ratio was less than 1, indicating that the competition among species was intense and the community structure was unstable. The natural secondary forest in Suichang was a community with Castanopsis eyrei as the constructive specie, but the community structure was unstable, the interspecific competition was fierce, and no dynamic balance among the dominant species.
