| 摘 要： | 采用样方法对水城县保华乡双桥水库工程区草本植物群落特征进行了调查研究。结果表明：水库工程区草本植物群落样方中,种密度为6.167×10^4种/hm^2,个体密度为8.067×10^6株/hm^2,主要以禾本科、菊科、唇形科、蝶形花科等科的植物占优势;草本植物优势种群在不同程度上均表现为集群分布;6个样地中,Simpson指数和Shannon指数的平均值分别为0.680和2.170,表明其物种多样性较丰富。

| Abstract: | To investigate and study on community characteristeristics of herbaceous plant in Shuangqiao reservoir, village Baohua of Shuicheng county, Quadrat sampling method was used. The main result was as follows： （1）The species density was 6.167×10^4 per hm^2, and the population density was 8.067×10^6 individuals per hmz in the samples . The dominant species usually belong to the family of Gramineae, Asteraceae,Labiatae and Papilionaceae. （2） The Dominant Species distribution pattern of herbaceous plants register as clumped in varying degrees. （3） The average values of Simpson index and Shannon index are 0.680 and 2.170 respectively, which indicate that the diversity and richness of herbaceous plants in Longdishui Nature Reserve were higher . |
