Niche and interspecific connectivity of dominant species of woody plants in evergreen broad-leaved forest of Jinzifeng National Forest Park
摘要
Abstract
[Objective]This study explore the ecological niche and interspecific association of the dominant species of woody plants in evergreen broad-leaved forest in Jinzifeng National Forest Park,Zhejiang Province,in order to provide a reference for ecological restoration and biodiversity conservation of subtropical evergreen broad-leaved forest.[Method]Niche composition,niche width,niche overlap index,niche similarity coefficient,variance ratio method,χ2 test,Pearson correlation coefficient,and Spearman rank correlation coefficient were used to study the niche and interspecific association of 21 dominant species of woody plants with important values≥1%.[Result](1)There were 113 species of woody plants belonging to 31 families and 62 genera in the evergreen broad-leaved forest community in Jinzifeng National Forest Park,including Fagaceae,Rosaceae,Lauraceae,and Ericaceae.(2)The importance values and niche widths of Schima superba,Castanopsis eyrei and Pinus taiwanensis were larger.They were established species in this community,and had higher niche overlap values and niche similarity coefficients with other dominant species of woody plants.The niche overlap values and niche similarity coefficients of 21 dominant species of woody plants were mainly concentrated in the range of 0.10-0.50.(3)The dominant species of evergreen broad-leaved forest woody plants in Jinzifeng National Forest Park showed a significant positive association(P<0.05).Among 210 species pairs,112 species pairs showed no significant positive association,49 species pairs showed no significant negative association,only 2 species pairs showed extremely significant positive association(P<0.01),8 species pairs showed significant positive association(P<0.05),39 species pairs showed no association.Spearman rank correlation test and Pearson correlation test showed no significant association.Species pairs accounted for 81.4%and 80.0%,respectively.The interspecific association was weak,with positive and negative association ratios greater than 1.(4)The regression analysis of Pearson correlation coefficient and niche overlap values of dominant tree species showed a extremely significant positive correlation(P<0.01).[Conclusion]The evergreen broad-leaved forest community in Jinzifeng National Forest Park is in the middle stage of succession,and the competition among species is gradually balanced.关键词
