台州地区雁荡山系和括苍山系森林群落结构与物种组成分析
Analysis of the structure and species composition of the forest communities in Yandang and Kuocang Mountains in Taizhou,Zhejiang Province,China
摘要
Abstract
[Objective]Taking the forest communities of Yandang and Kuocang Mountains in Taizhou as the research objects,this study focuses on the differences of forest community structure and species composition of 2 mountain systems and their causes,which provides technical support for understanding the changes of evergreen broad-leaved forests in Taizhou.[Method]Based on the survey of 11 plots in Yandang Mountain and 15 plots in Kuocang Mountain(20 m×20 m),species composition,diameter structure and their relationships with the environmental factors were analyzed using methods such as Redundancy Analysis(RDA).[Result]Forest communities of Yandang Mountain recorded 67 species of trees,belonging to 31 families and 46 genera while those of Kuocang Mountain recorded 89 species of trees,belonging to 38 families and 62 genera.Species having important values≥1%in the forest communities of Yandang and Kuocang Mountains were Schima superba,Liquidambar formosana,Cinnamomum camphora,Cunninghamia lanceolata,Loropetalum chinense,Eurya rubiginosa,Cyclobalanopsis glauca,Castanopsis sclerophylla,Adina pilulifera,Eurya muricata,Styrax faberi.The important value of Schima superba in the forest communities of Kuocang Mountain was 27.37%,which was 16.80%higher than that in Yandang Mountain.Shannon-Wiener index and Pielou evenness index of the forest communities of Yandang Mountain were significantly higher than those of Kuocang Mountain(P＜0.05).The total individual diameter distribution of species in 2 forest communities showed inverted"J"shapes.Total nitrogen,rock exposure rate,pH,soil total carbon and electrical conductivity were the main factors affecting the diversity indexes of forest communities of 2 mountains.[Conclusion]Shannon-Wiener index and Pielou evenness index of Yandang Mountain forest community were significantly higher than those of Kuocang Mountain forest communities.The main difference between 2 mountain forest communities is that the important value of Schima superba in Kuocang Mountain forest community is significantly higher than that in Yandang Mountain.关键词
