摘要
为进一步了解和改善大连市公园绿地植物配置模式,采用典型样地取样法,对大连市5个公园样地的植物配置模式进行了研究,并在设置的30个样方内进行了植物组成、生长型、群落密度、乔灌比和覆盖度等的调查。结果表明:(1)配置模式所占比例分别为乔灌草型70%,乔灌型10%和乔草型20%,主要采用乔灌草型;(2)乔木覆盖度是62.94%,灌木覆盖度是6.95%,草本覆盖度是66.51%。总体覆盖度较高,中层结构简单;(3)乔木层的平均密度为每300m214株,灌木层的平均密度为每300m217株,灌木层密度略大于乔木层;(4)应用最多的乔木有水杉和银杏等7种;应用的主要灌木有冬青和小叶黄杨等8种;应用的地被植物有花叶玉簪和矮牵牛等12种;草坪草都是早熟禾。
In order to further understand and improve the plants disposition patterns in green space of public gardens in Dalian city,by using typical sample sampling method, the plants disposition patterns in 5 parks have been researched. What＇s more, the plants composition, growth form, community density, the ratio of arbores and bushes and coverage in the given thirty quadrats were surveyed. The results showed thatz （1）The arborshrub-grass disposition pattern took up 70 percent,the arbor-shrub disposition pattern took up 10 percent and the arbor-grass disposition pattern took up 20 percent. The arbor-shrub-grass disposition pattern was mainly used. （2）The coverage of arbor was 62.94 percent,the coverage of shrub was 6.95 percent and the coverage of grass was 66.51 percent. The overall coverage was high and the middle structure was simple. （3）The average density of arbors was 14 plant per 300 mz ,the average density of shrubs was 17 plant per 300 m2 and the latter was slightly bigger than the former. （4）The.;ost： used arbors were Metasequoia glyptostroboides, Ginkgo biloba ,etc. 7 plants;the most used shrubs were Ilex purpurea ,Buxus sinica ,etc. 8 plantsiHosta planta ginea ＇Fairy variegata＇ and Petunia hybrid ,etc. 12 herbal plants were used as cover ptant;The Poa was used as the only type turfgrass.
