巾子峰国家森林公园常绿阔叶林群落特征及其与土壤关系
Characteristics of broad-leaved evergreen forest communities and their relationships with soil in Jinzifeng National Forest Park
摘要
Abstract
This study investigated the community characteristics of the evergreen broad-leaved forest in Jinzifeng National Forest Park and their relationships with soil properties,aiming to elucidate the underlying mechanisms of biodiversity maintenance.The data of plant community survey and soil chemical analyses in the park were integrated for comprehensive ecological assessment.The study examined the species-area cumulative curve,species composition,floristic elements,α-diversity indices,and diameter at breast height(DBH)structure,while employing Mantel tests to assess correlations between species diversity and soil chemical variables.The species-area cumulative curve exhibited a rapid initial increase followed by gradual saturation,indicating that the sampling effort adequately captured the species composition of the mid-elevation zone within the park.A total of 4 810 woody individuals(DBH≥1 cm)were recorded,distributed across 105 species,58 genera,and 29 families.Evergreen species(3 697 individuals)substantially outnumbered deciduous species(1 113 individuals).Dominant families included Fagaceae,Rosaceae,Ericaceae,Lauraceae,and Theaceae.Genera with tropical floristic affinities(25 genera)exceeded those of temperate origin(15 genera)by a ratio of 1.67∶1,indicating the predominance of tropical elements in the flora.The mean DBH of woody plants was 6.10 cm,and the DBH distribution displayed a typical inverted"J"shape,with 91.56%of individuals falling with the range of 1 cm≤DBH<20 cm,suggesting robust natural regeneration and favorable community dynamics.Mantel test results revealed that soil available phosphorus and nitrate nitrogen levels were correlated with α-diversity indices(P<0.01,P<0.05).关键词
