Links between important values of (Cremastra appendiculata) and elevations by long-time investigation and qualitative analysis and quantitative statistics of "Big data"

(Cremastra appendiculata) of treating lumbago and arthritis not only is a vital medicinal material plant, but also it is a widely distributed wide plant species. This plant species is widely distributed elevation from 500m to 3100m in Mei County of China. However, understanding dynamics of Important Value of this species is very difficult along elevation. This research explained that links between Important Value of this species and elevation is the significant positive correlation from 500m to 1500m (P<0.01) as well as the links between Important Value of this species and elevation are the significant negative correlation from 1500m to 3100m (P<0.01). This study provides six natural landscape types and a series of areas ecological adaptation for finding new medical species along different elevation. Thus, this research has vital theoretical and practical significance for medicinal plant protection at spatial-temporal-environmental-disturbance scales (STEDS).
