Relation between fresh biomass of plant species (Senecio L.) and elevation in Shan County

A key plant species (Senecio L.) not only is a vital multilevel functional medicinal material of indications of respiratory tract infections, tonsillitis, pharyngitis, pneumonia, conjunctivitis, enteritis, dysentery, but also it is a widely distributed wide plant species. This plant species is widely distributed elevation from 500m to 1500m in six landscapes and vegetation ecosystems in Shan County of China. However, understanding dynamics of dry biomass of this species is difficult along elevation. This research explained that the relation between fresh biomass of the species and elevation is a significant positive connection from 500m to 1000m (P<0.01) as well as the links between fresh biomass of this species and elevation is a significant negative connection from 1000m to 1500m (P<0.01). This study provides six ecosystem types and a series of areas ecological adaptation for finding new medicinal species. Therefore, this study has vital theoretical and practical significance for medicinal plant protection along different elevation and environmental gradient over the spatial-temporal-environmental-disturbance scales (STEDS) in the multilevel green space diversity.
