续断居群主要活性成分的空间结构及地理分布规律

Spatial structure and geographic distribution of major active component in medical herb Dipsacus asperoides population

为研究贵州省续断居群主要活性成分的空间结构及地理分布规律,作者在贵州省的38个续断居群内采集获取了每个居群的川续断皂苷Ⅵ含量,应用空间统计和传统统计方法发掘续断居群的空间变异规律,并结合环境变量来分析续断居群主要活性成分的群组与环境因子群组的地理分布规律。结果显示:贵州省续断居群主要活性成分的空间结构在全局空间上是完全随机的分布,而在局域空间上有2个聚集点,具有较高的正相关性。续断居群川续断皂苷Ⅵ组群的组间环境因子得分差别较大,组内环境因子得分差别较小。

To study the spatial structure and geographic distribution of major active components in medical herb Dipsacus aspe- roides population, in Guizhou province, the author obtained the asperosaponinVI content among 38 D. asperoides population points. Using spatial statistic and traditional statistic, the spatial variation pattern has been found. Combining the environment variables, it is tried to reveal the geographic distribution rules between group of major active component in medical herb D. asperoides population and group of environmental factors. The results show：the spatial structure of major active component in medical herb D. asperoides popula- tion is randomly distributed in global space, but has two aggregation points which have a high positive correlation in local space; envi- ronmental factors value for group of major active component in medical herb D. asperoides population has a large difference in the interi- or-group, but environmental factors value has a small difference in inter-group.
