雷公山自然保护区秃杉保护成效初步研究

雷公山自然保护区位于贵州省黔东南州雷山、榕江、剑河和台江四县交界,是以保护秃杉为主的保护区,自1983年建立距2018年也有35年的历史。经调查统计,天然秃杉种群数量胸径在10cm以上分别为：1985年有5000株左右,2005年有4922株,2015年实测5452株;秃杉群落中物种多样性丰富,即科属种保持在60～80科、110～190属、140～240种。可见,雷公山自然保护区这35年来天然秃杉种群及群落中物种多样性得到了有效保护,保护成效显著。

The Preliminary Study on Conservation Effect of Taiwania cryptomerioides in Leigongshan Nature Reserve

Founded in 1983, mainly to protect Taiwania cryptomerioides, Leigong Mountain Nature Reserve has a history of 35 years. According to the investigation and statistics, the population number of the natural T. cryptomerioides with the DBH above 10cm was about 5000 in 1985, 4922 in 2005 and 5452 in 2015. The species diversity of T. cryptomerioides community is rich, that is, the species of family and genus maintain in 60 ~ 80 families, 110 ~ 190 genera, 140 ~ 240 species. It can be seen that the species diversity of natural T. cryptomerioides population and community in Leigong Mountain Nature Reserve has been significantly protected in the past 35 years, and the protection effect is remarkable.
