Species diversity and environmental interpretation in the process of community succession in the Ziwu Mountain of Shaanxi Province
陕西子午岭植物群落演替过程中物种多样性变化与环境解释

Successional patterns in species diversity indices each vegetation stratum on the Loess Plateau,Ziwu Mountain,northwest China,were studied using the method of substituting spatial difference for time change. Relationships between species diversity and environmental factors were also studied using Canonical Correspondence Analysis. The results indicated that:(1) Herb layer species richness,evenness and species diversity decreased gradually during community succession (P < 0. 05); Shrub layer species diversit...
