Abstract: (Cremastra appendiculata) not only is a vital medicinal material plant by treating lumbago and arthritis, but also it is a widely distributed wide plant species from 500m to 3100m in Mei County of China. However, understanding links between total biomass of roots cuticle and daily solar radiation is difficult. This study explained that there is the increasing of total biomass of roots cuticle with increasing of daily solar radiation as well as links between total biomass of roots cuticle and daily solar radiation is the significant positive correlation from 20.578mol/m2•d to 24.158mol/m2•d along elevation from 500m to 1500m (P<0.01); there are decreasing of this total biomass of roots cuticle with increasing of daily solar radiation as well as the linkages between this total biomass of roots cuticle and daily solar radiation is the significant negative correlation from 24.15mol/m2•d to 27.246mol/m2•d along elevation from 1500m to 3100m (P<0.01). This research provides a series of areas ecological adaptation of daily solar radiation and six landscapes of this species. Therefore, this has vital theoretical and practical significance by medicinal plant species protection for better future of human health, ecosystem services and ecosystem functions along daily solar radiation.
