南矶山碟形湖湿地植被群落分布特征与评价
|
摘要
为阐明南矶山碟形湖湿地植物物种多样性特征,采取了多样性指数等调查方法对代表性碟形湖优势植被群落进行了分析。结果表明,研究区域植物物种共有10科18属28种,其中丰富度依次为芦苇群落>南荻群落>苔草群落;多样性指数依次为芦苇群落>南荻群落>苔草群落;均匀度指数依次为南荻群落>芦苇群落>苔草群落;优势度指数依次为苔草群落>芦苇群落>南荻群落。在研究的3个群落中,丰富度、多样性指数、均匀度指数和优势度指数在不同群落中存在显著的差异,并体现出多样性指数以及丰富度高的群落往往优势度指数就小的一般规律。南矶山湿地碟形湖区物种多样性差异与湖泊水位、植物繁殖特性、物种种间竞争力是显著相关的,并充分体现出南矶山湿地生境的多样化特征。
In order to elucidate the characteristics of plant species diversity in the Shallow-Lake District of Nanjishan wetland reserve,the dominant vegetation communities in the representative Shallow-Lake District were studied with r diversity indices and other survey methods.The results show that there were 10 families 18 genera and 28 species,of which the richness order was as follows:Phragmites community > Nandi community > Carex community;The diversity index was as follows:Phragmites community > Nandi community > Carex community;The evenness index was as follows:Nandi community >Phragmites community > Carex community;The dominance index was as follows:Carex community > Phragmites community> Nandi community.In the three communities studied,there were significant differences among different communities about the richness,diversity index,evenness index and dominance index,which reflected the general rule that the high index of diversity and richness often have a small dominate index.The species diversity is significantly related to the lake water level,the characteristics of plant reproduction,and the species competitiveness in the Shallow-Lake area at the Nanjishan wetland reserve,which can fully reflect the diversified characteristics of the Nanjishan wetland reserve.
