摘　　要：公园绿地对城市的环境与发展起着重要作用,为掌握安康市北辰公园植物群落情况、植物配置模式及物种多样性,在安康市北辰公园展开实地踏查和取样调查,对园林植物详细数据进行计算和分析,统计各植物的重要值、丰富度指数、多样性指数等。结果表明:北辰公园主要应用的园林植物有36科52属56种。乔木层中重要值前三名是香樟、广玉兰、桂花,灌木层重要值前三名是海桐、女贞、栀子,草本层中重要值以狗牙根最高。乔木层物种丰富度指数和多样性指数最高,草本层最低。说明北辰公园植物群落和景观配置优良,不足之处在于其草本植物品种较少,植物群落大多应用乡土树种,外来树种栽植过少,建议多增加本地已引种可行的外来树种栽种。In the modern life,the park green space plays an important role in the urban environment and development.In order to master the garden plant disposition pattern,plant community structure and species diversity of Beichen Park in Ankang City was selected as the object to carry out investigation and research.Through field investigation,we calculated and analyzed a large amount of plant data,and counted the important value,richness index and diversity index of each plant.The results showed that there were 56 species,52 genera and 36 families of garden plants in Beichen Park.The first three important values of tree layer were Cinnamomum camphora,Magnolia grandiflora and Osmanthus fragrans.The first three important values of shrub layer were Pittosporum tobira,Ligustrum lucidum and Gardenia jasminoides.The most important value of the herb layer was Cynodon dactylon.The species richness index and diversity index of arbor layer were the highest,and those of herb layer were the lowest.The plant community and landscape of Beichen Park were well arranged,but the shortage was that there were few herbaceous plant species,the plant community mostly uses native tree species,and the exotic tree species were seldom planted.It is suggested to increase the planting of exotic tree species which are feasible through long-term test.
