云南省红豆杉资源及可持续利用的对策

Taxus spp Resources in Yunnan and the SustainableExploration Strategies

云南省是我国红豆杉资源的主要分布区之一，红豆杉水平分布较广，全省３４ 个县（市）均有分布．多散生分布于亚高山针叶林、中山上部针阔混交林、湿性常绿阔叶林和季风常绿阔叶林；无纯林，少有以它为优势的林分．天然分布面积２２１９１９ｈｍ２ ，３５４０９２０ 株蓄积７０７ ８４４ ｍ３ ．红豆杉是珍贵的药用和材用树种，由红豆杉提取的紫杉醇（Ｔａｘｏｌ）抗癌药物的临床应用，使红豆杉资源数量与社会需求的矛盾日益突出．红豆杉资源的合理利用必须在保护好现有种群数量和质量的基础上，采取“适度利用与发展人工原料林基地”并重的策略，才能实现红豆杉资源的可持续利用．

Yunnan is one of the major distribution area of Taxus spp.,which is widely distributed over 34 counties of the provine.Taxus spp are majorly found in mixed stands of subalpine meedle leaved forests,mixed forests at high elevation area,wet evergreen broadleaved forest and moonsoon evergreen broadleaved forest.3?540?920 steins are found in its natural distribation area of 221?919?hm 2,with a stock of 707?844?m 3. Taxus spp.are valuable for both medicinal use and timber.The Taxol extracted from the trees has been used for treating cancer with ideal effect,which has caused a gap between demand and supply.To ensure a sustainable use, Taxus spp.resources must be explored rationally while plantations shall also be set up to prooide marketneed.Inthis way,the natural population of Taxus spp may be maintained.
