The Characteristics of Species Diversity in Different Stages in Castanopsis fissa Communities Under Forest Enclosing and Tending

Characteristics of species diversity in Castanopsis fissa communities in different stages under forest enclosing and tending in Nanping city of Fujuan province was analyzed in this paperThe results showed that:the numbers of species,total number of individuals,index of species diversity,and evenness of community in tree layer in young stand stage were larger than those in nearmature stand stage,but ecological dominance had an opposite trend;in young stand stage,the numbers of species,total number of individuals,and ecological dominance of community in shrub layer were larger than those in nearmature stand stage,but index of species diversity and evenness showed an opposite trend;the numbers of species,index of species diversity,and evenness of community in herb layer in young stand stage were larger than those in nearmature stand stage,but total number of individuals and ecological dominance had an opposite trend
