岷山中段高山峡谷区主要森林群落林下植物多样性研究
Understory Plant Diversity of Major Communities in the Alpine and Canyon Region of the Middle Part of Minshan Mountains
摘要
Abstract
Based on the field survey data,the application of Margalef richness index,Shannon-Wiener diversity index,Pielou evenness index and Simpson dominance index were studied in the area in 10 kinds of main forest community in understory plant diversity.The results showed that the species composition and diversity of understory shrubs and herbaceous plant presented significant differences in different communities,canopy density had a significant influence on species composition and diversity.The species diversity of understory in forest communities presented as evergreen and deciduous broadleaved mixed forest ＞ broadleaved forest ＞ plantation.The species diversity index of different forest communities basically presented as herb layer ＞ shrub layer.Vegetation restoration in the mountain area should be mixed forest forestation,evergreen tree species and deciduous tree species collocation at the planting.Tree species should be selected native tree species that suitable for environmental characteristics and altitude.关键词
