Diversity and distribution of Rhododendron species in Tangjiahe area of Giant Panda National Park
通过对四川大熊猫国家公园唐家河片区杜鹃花属植物的野外调查及资料收集整理发现,区内现有杜鹃花属植物2亚属、3 组、10 亚组,涵盖16种1亚种1变种,共计18个分类群;杜鹃花物种在区域内主要分布于2 000～3 000 m 的海拔区域,物种多样性整体随海拔升高呈现先增加后减少的趋势;区内杜鹃花属植物分布广泛,具有较高的景观及药用价值,岷江杜鹃、美容杜鹃、山光杜鹃、麻花杜鹃、毛肋杜鹃等可作为选育新品种的亲本材料,建议在保护的基础上加强资源育种和利用工作.
Through field investigation and data collection of Rhododendron species in Tangjiahe area of Sichuan Giant Panda National Park,it was found that there were 2 subgenera,3 groups,and 10 subgroups within this region,including 16 species,1 subspecies,and 1 variety,18 taxa in total.Rhododendron species were mainly distributed at the altitude of 2,000-3,000 m,and the overall species diversity first increased and then decreased with the elevation.Rhododendron plants were widely distributed in the area,exhibiting high ecological and landscape application value.Some species could be served as parent materials for breeding new cultivars,such as Rhododendron hunnewellianum,R.calophytum,R.oreodoxa,R.maculiferum and R.augustinii.In addition to preserve Rhododendron plant resources in the area,it is recommended to strengthen the breeding and utilization of resources.
