云南龙棕资源调查及生物学特性的研究

龙棕(Trachycarpus nana)为特产于云南的国家二级珍稀保护植物,通过调查,初步查明龙棕在云南的分布状况,发现了南华、姚安等6个新分布点。确认龙棕在云南主要分布于滇中高原,云南楚雄地区是其分布中心。同时对龙棕的生物学特性及生态学习性进行了初步研究,为保护和开发利用这一珍稀濒危植物资源提供科学依据。并且对龙棕濒危原因作了初步探讨,提出了相应的保护措施。

Surver of Yunnans Trachycarpus nana and its biological features

Trchycarpus nana is a national grade-2 protected rare plant that grows in Yunnan Province. On the basis of a survey, the paper has ascertained the areas of the plants growth in Yunnan Province and found six more growth spots as NanHua and YaoAn. It confirms that Trachycarpus nana plant grows principally in Central Yunnan Plateau, with Chuxiong at its heart. The paper also makes a preliminary study of the plant's biological and ecological features and thus paves the way for protection and utilization of this rare and near-extinctive plant.A probe is also made into the causes of the plant's near-extinctiveness ,so as to facilitate taking protective measures.
