湖北省珍稀濒危植物黄梅秤锤树种群现状研究

Study on Natural Population of Sinojackia huangmeiensis in Hubei Province

[目的]探明湖北珍稀濒危植物黄梅秤锤树的种群现状。[方法]采用邻接格子法和直接计数法对湖北省特有珍稀植物黄梅秤锤树的种群数量及分布格局进行调查研究。[结果]该种目前资源总量为456株,比2005年发现报道的数量200余株有所增加。采用方差/均值比率法对黄梅秤锤树种群分布格局类型进行分析,表明该种群分布格局类型为集群分布。[结论]该研究可为黄梅秤锤树的进一步保护、研究及开发利用提供参考。

Objective] To study the natural population of Sinojackia huangmeiensis in Hubei Province.[Method] The population size and distri-bution pattern of the unique endemic plant S.huangmeiensis in Hubei Province were investigated by using the adjacent grid method and direct counting method.[Result] There were 456 plants of S.huangmeiensis currently,more than the quantity reported in 2005 （above 200 plants）.The distribution pattern of S.huangmeiensis was analyzed by variance/mean ratio method,and the results showed that the distribution pattern of the population was the cluster type.[Conclusion] The research can provide references for the further protection,research,development and utilization of S.huangmeiensis.
