采取随机加局部控制抽样法,对石家庄市三大综合公园植物群落物种组成、植物来源、物种多样性指数等进行了调查统计和比较分析。结果表明:石家庄市公园群落物种组成中本地种在数量和地位上均具有明显优势;各公园Margalef物种丰富度指数、Simpson多样性指数和Shannon-Wiener指数均表现为乔木层>灌木层>草本层;Pielou均匀度指数在各公园的3个群落层次上顺序不一。
Random sampling method was adopted to investigate the species composition, plant origin and species diversity index of plant communities in the three major integrated parks in Shijiazhuang City. The results showed that there were obvious advantages in the species and status of species in the park community in Shijiazhuang City. The Margalef species richness index, Simpson diversity index and Shannon-Wiener index in each park showed the characteristics of arbor layer> shrub layer> herb layer The Pielou evenness index varied in order at three community levels in each park.
