通过对广西千层塔主要分布区10个野外样点和总样方量30.5 km2的调查,结合6个标本馆45份千层塔馆藏标本及现有文献的研究表明:千层塔在广西主要分布在桂东北、桂东南等地,实际分布生境总面积约1 886.3 km2;野外生物量调查得到了千层塔在不同地理区域的生物量分布格局,并结合科学评估方法对样方调查结果和间接推导数据的权重分析及环境参数进行评估,初步确定广西千层塔天然生物量为413.1 t;进一步考虑人为采集能力的前提下,估测广西千层塔的理论可采量20.6 t.千层塔资源分布分散,且主要分布在自然保护区和风景区范围内,因此,不宜大规模开采,应进一步寻找科学合理的途径解决资源紧缺问题.

By investigating 10 wild sample stands(with total area of 30.5 km2)located in the main distribution area of Huperzia serrata in Guangxi,combining with the studies of more than 45 specimens stored in six herbarium as well as the existing documents,it's found that northeast and southeast Guangxi were the main distribution area of H.serrata,and an actual distribution area was 1 886.3 km2or so;its biomass distribution pattern at different areas were obtained via field biomass investigation,and the assessment of direct sampling results,indirect reasoning data,and envirpnmental parameter were made with the scientific method of evaluation. It could be ascertained that the natural storage capacity of H.serrata was 413.1 t;based on this figure and the factor of manpower collection,the theoretical exploitation capacity was 20.6 t. However,the large-scale exploitation should not be feasible because of their scattering status and relative concentrated distribution areas in the natural reserves and scenic spots. Therefore,to avoid the resource shortage of H.serrata,it must rely on other scientific and rational approaches.
