黄河三角洲自然保护区典型植物群落物种组成及多样性梯度变化
Changes in Floristic Composition and Species Diversity of Plant Community along Environment Gradient in the Yellow River Delta National Natural Reserve, China
摘要
Abstract
The typical wetlands in the Yellow River Delta National Natural Reserve had been selected to research on the variation rules of plant community composition and diversity along the environment gradient explored. The results showed that from the community of Ass. Phragmites australis-Typha angustifolia to Ass. Suaeda salsa, (1) the species richness fluctuated and there was the highest species richness in the community of Ass. Salix matsudana-Phragmites australis-Imperata cylinddrica var. major, while there was the lowest species richness in the community of Ass. Suaeda salsa;(2)αdiversity of the community had a different fashion compared with species richness, and the Shannon-Winner diversity and Pelou evenness index had a pattern of fluctuated downward trend, while Simpson dominance index showed a pattern of fluctuating upward trend;(3) the changes of theβdiversity pattern were not the same, and Jaccard index showed a fluctuated change, while the Copy index had a pattern of fluctuated downward trend. The changes of typical community composition and species richness in the Yellow River Delta wetlands were mainly related to the changes of habitats.关键词
