采用实地调研、文献查阅、走访等方法,对玉屏侗族自治县境内古树名木的种类、数量、树龄,以及保护级别、生长势及植物区系特征进行调查,结果显示:玉屏侗族自治县共有古树名木485株,分属23科30属34种,其中,一级古树32株,二级古树38株,三级古树415株;古树名木的数量与海拔和坡度呈极显著相关,不同树种海拔、坡度分布差异较大;古树具有南北区系过渡特征,属的分布具有以温带分布为主,热带分布为辅的特点。通过调查发现,玉屏侗族自治县古树名木保护中存在缺乏保护资金,养护水平低,重保护轻利用等问题。针对相关问题,提出拓宽融资渠道,建设专业技术队伍,新建古树公园等保护和管理对策。

Based on the spot investigation,consulting document and interviewing,the species,quantities,ages,protection grades,growth potential,floristic characteristics,protection conditions,current problems of the ancient or rare trees were studied in Yuping Dong Autonomous County. The result showed that there were up to 485 ancient or rare trees in Yuping Dong Autonomous County,which belong to 23 families,30 genera,34 species. There are 32 trees over 500 years,38 trees between 300 years and 499 years,415 trees between 100 years and 299 years.There was significant correlation with the altitude,slope and the number of ancient or rare trees,there were many differences among them. The floristic characteristics of the ancient or rare trees were also analyzed,the result showed that the temperate distribution-type had a significant dominance,and the tropic distribution-type played a secondary role in the floristic characteristics. There are lots of problems in the protection of ancient or rare trees,such as the shortage of funds,low maintenance level,etc. Therefore,some effective countermeasures should be adopted,including widen financing channel,developing professional contingent,constructing Ancient Trees Park,etc.
