紫金山栓皮栎枫香混交林群落结构与物种多样性
Plant diversity in a mixed plantation of Quercus variabilis and Liquidambar formosana in the Zijinshan Mountion
摘要
Abstract
In order to understand the plant diversity in a mixed plantation of Quercus variabilis and Liquidambarformosana in the Zijinshan Mountain,the importance values of the tree layer species,the age structure of the dominant populations and the species diversity,richness and species evenness were analyzed.The results showed the mingled forest of Quercus variabilis and Liquidambarformosana had 102 species belonging to 59 families,93 genera.In the tree layer,Quercus variabilis,Liquidambarformosana and Pinus massoniana had the dominant positions,and the sum of the importance values of the three species reached 77.88％.Quercus variabilis in this community approximated to the stable population and Liquidambarformosana was a typical growing population.Pinus massoniana appeared to be a typical decreasing population.In the future,Quercus variabilis and Liquidambarformosana will continue to be the dominant positions in this area,but Pinus massoniana will be replaced by the species that has better renewal capacity.In this community,the Simpson's and Shannon-Wiener's indices of the shrub layer were the greatest,followed by the herb layer and the tree layer.The Simpson's and Shannon-Wiener's indices of the shrub layer,the herb layer and the tree layer were 0.948 and 3.370,0.894 and 2.480,0.717 and 1.690,respectively.The species richness index of the tree layer was close to that of the herb layer,which was 24 and 22,respectively.The shrub layer had the greatest species richness index of 68.The Pielou's index of the shrub layer was close to that of the herb layer,which was 0.799 and 0.802,respectively.The tree layer had the smallest Pielou's index of 0.532.关键词
