武当山盾叶薯蓣生态环境及其分布规律

The Ecological Environment of Dioscorea Zingiberensis Wright and Its Distribution Regularity in Wudangshan Mountain

通过调查，笔者基本摸清了武当山一带盾叶薯蓣的生态环境和分布规律．根据分析，盾叶薯蓣（干片）中皂甙配基含量为1．05％～6．8％，平均含量为3．11％，由此证明武当山一带是我国盾叶薯蓣皂甙配基含量较高的产区，但株间和生态环境的差异与皂甙配基含量的高低有一定关系．

Through investigation, this paper found out the ecological environment of Dioscorea Zingiberensis Wright and its distribution regularity in Wudangshan mountain. According to the analysis,the diosge nine content of Diescorea Zingiberensis wright is from 1.05 % to 6. 8 %,and the average reached 3. 33%,which proved that Wudangshan mountain is one of the productive areas of Diescorea Zingiberensis Wright with high diosgenin content in China,but diosgenin content differs greatly between different plants and ecologicaI environment.
