陕西省兰科植物种类及其分布研究

Study on the species and distribution of orchidaceae in Shaanxi province

对陕西省兰科植物种类及分布进行了调查研究.调查地点涉及兰科植物分布相对集中的30个县以及植物物种多样性相对丰富的15个自然保护区,野外调查在不同季节进行;分别对陕西省兰科植物进行了资源调查、标本采集和图片拍摄.对采集的标本通过查阅相关文献和与相关植物标本馆(室)兰科植物标本进行对比研究,共发现陕西省野生兰科植物41属82种,属、种数比以往的记录有大幅度增加.在此基础上,对陕西省兰科植物资源的合理开发、保护和管理提出了建议.
