Plant biological diversity in natural secondary forests on Mao’es Mountains

Abstract

The forest plant biological diversity investigations were conducted in Laoyeling Forest Ecological Experimental Station on Mao’er Mountains in eastern Heilongjiang Province. Sample plots were six different forest communities. Field works were divided into three seasons: spring, summer and autumn in one year. The results showed that forest plant biological diversity varied with seasons as well as growth forms. Herb species diversity values were the highest in the community growth forms. Diversity indices No,H′ andE ₁ were selected out as the best richness, diversity and evenness indices to indicate the biological diversity in forest community.
