摘要
为更好地掌握怒江州兰科植物资源状况和分布特征,该研究基于云南省野生兰科植物资源野外调查成果和文献资料,分析其保护级别、濒危等级、特有性、属的分布区类型、地理和海拔分布状况。结果表明:(1)怒江州分布有兰科植物63属218种,其中被《国家重点保护野生植物名录(2021)》收录的有38种,被《云南省生物物种红色名录(2017版)》收录的有95种,中国特有种20种,云南特有种11种。(2)属的分布区类型可划分为10种类型和3种变型,以热带成分占优势,温带成分是其重要组成。(3)垂直分布呈两端低中间高分布,主要分布于海拔1400~2399 m,并在1400~1899 m处达到峰值。(4)在水平分布上,贡山(155种)>泸水(78种)=福贡(78种)>兰坪(24种)。综上,怒江州兰科植物资源丰富,建议加强保护体系建设和兰科植物资源调查及科学研究,并尽快制定地方性野生兰科植物保护条例。
In order to better understand the status and distribution of orchid resources in Nujiang Prefecture of Yunnan Province,this study,based on the results of field survey and literature review of orchid resources,we analyzed the protection grade,endangered grade,endemism,distribution area type of genus,geographical and altitude distribution.The results showed that there were 218 species of orchids in Nujiang Prefecture,belonging to 63 genera.Among them,38 species are listed in the National Key Protected Wild Plants List(2021),95 species in the Red list of biological species in Yunnan Province(2017),20 species endemic to China and 11 species endemic to Yunnan.At generic level,there were 10 types and 3 subtypes of orchids in Nujiang Prefecture.The tropical elements are dominated,the temperate elements are its important component.The vertical distribution of orchids showed a“low-high-low”pattern,which was mainly distributed at 1400-2399 m above sea level and reached the peak at 1400-1899 m.The richness of orchid plants of horizontal distribution presented Gongshan(155 species)>Lushui(78 species)=Fugong(78 species)>Lanping(24 species).Based on the above analysis,Nujiang Prefecture is rich in orchid plants.It is recommended to strengthen the construction of a protection system,survey and scientific research of orchid plants,and formulate local wild orchid plant protection regulations as soon as possible.
