太白山药用植物的中药药性与海拔相关性研究

Correlation Study of Medicinal Properties and Altitude for Plants in taibai Mountain

目的通过对太白山药用资源进行野外普查及整理分析,为以后的药用植物资源利用提供参考和依据。方法运用统计学方法及SPSS软件中相关分析法。结果药用植物的药味统计中,苦味类的所占比例最大,占总数的50%,其次是甘味类的占总数的17%,辛味类的占总数的14%;其药性的统计中,寒性药用植物占总数的29%,平性药用植物占总数的25%,温性药用植物占总数的21%,凉性药用植物占总数的20%;其功效的统计中,清热类药用植物占总数的33%,活血类药用植物占总数的18%,祛风湿类药用植物占总数的17%。其功效与海拔的关系为:止血类、祛风湿类及利水渗湿类药用植物与海拔呈显著负相关性,活血类、清热类及化痰类药用植物与海拔呈负相关性。收涩类、解表类、补虚类、温里类及理气类药用植物与海拔无相关性。结论太白山药用植物的中药药性与海拔有一定的关系。具有苦味、寒凉性的药用植物种类多,多具有清热、活血、祛风湿的功效,基本生长于海拔2300 m以下,药用植物随着海拔的升高,种类在逐渐减少。

Objective： To survey and sort the medicinal plant resources of Taibai Mountain,which will provide reference for medicinal plant resources utilization and planting. Methods： correlation analysis in SPSS software was applied.Results： Among the herbal taste analysis of medicinal plant,bitter taste herbs held the largest proportion,accounting for50 % of the total,followed by sweet category accounted for 17 % of the total,pungent category accounted for 14 % of the total. the cool property medicinal plants accounted for 29 % of the total,mild medicinal plants accounted for 25 % of the total,Warm property medicinal plants accounted for 21% of the total,cold medicinal plants accounted for 20 %. Purging heat medicinal plants accounted for 33% of the total medicinal plants,promoting blood circulation drugs accounted for 18% of the total,medicinal plant belonging to removing rheumatism category accounted for 17 %. The relationship between functions and altitude are as follows： blood stasis herbs and removing rheumatoid and filtrating water functional plants were positively correlated with altitude. Purging heat,activating blood circulation and resolving phlegm functional medicinal plants were negatively correlated with altitude. astringents,herbs for relieving Exterior Disorder,tonification,interior warming and regulating qi have no correlation with altitude. Conclusion： there has a certain relationship between medicinal herbal property and altitude. there are much bitter and cold taste class categories medicinal plants,which can be used for Purging heat and resolving phlegm,activating blood circulation substantially growing at an altitude of 2300 m or less.With increasing altitude,species of medicinal plants are decreasing.
