High Gradient Effects of Forest Biomass Energy in Mountainous Region—A Case of Meili Snow Mountain

Integrated using methods of forest biomass and productivity, Geographic Information System, and biogeographic statistics, this paper is quantified the reserves of forest biomass energy, and its relationship to elevation, slope degree and slope aspects. The results indicate: the forest biomass energy in eastern Meili Snow Mountain have significant spatial heterogeneity and correlation, in which the forest biomass energy is increasing with elevation in between 2000 to 3900 meters above sea level, and is decreasing while the elevation is higher than 3900 meters; The quantity of forest biomass energy is distributed mainly in between of 25 to 35 slope degree. It has obvious difference among slope aspects, in which eastern, southeastern, and northwestern aspects are relatively centralized. The correlation analysis between forest biomass energy and elevation, slope degree, and slope aspects indicate the negative correlation to elevation and slope aspect, and positive correlation to slope degree with a correlation coefficient of −0.17, −0.86 and 0.30, respectively. Therefore, the forest biomass energy concentrated at the middle belt of the Meili Snow Mountain formed an annular ecological corridor and provided a good living environment for mountainous ecosystems and local peoples.
