黑河流域甘州区湿地植物物种多样性研究OA北大核心CSCDCSTPCD
Plant Species Diversity of Wetlands at Ganzhou District of Heihe River Basin
以芦苇群落和西藏嵩草两个群落为对象,研究了两个群落的植物物种及组成特征。结果表明,芦苇群落以芦苇为优势种,以西藏嵩草为亚优势种,二者重要值之和为0.434 2;西藏嵩草群落以西藏嵩草为优势种,重要值为0.187 6。物种多样性分析表明,两群落的物种多样性指数（H）和均匀度指数（J）均波动幅度较大,优势度（D）值波动幅度较小;芦苇和西藏嵩草群落的多样性指数与均匀度指数呈现出显著的正相关关系,但与物种丰富度指数无明显相关,而与生态优势度指数呈明显的负…查看全部>>
Plant species and composition characteristics were investigated in Phragmites communis community and Kobresia tibetica community.The results show that Phragmites communis and Kobresia tibetica were the dominant and the subdominant species in Phragmites communis community,with important values of 0.434 2 as in sum.Kobresia tibetica was the dominant species in Kobresia tibetica community,with an important value of 0.187 6.Species diversity analysis showed that…查看全部>>
