| Abstract: | Based on the improved CASA model， in this paper， the net primary productivity （NPP） quality of vegetation in the Qilian Mountains is estimated， and the vegetation and soil carbon sequestration and value are further estimated in the study area in 2005， 2010 and 2015 based on photosynthesis equation and carbon cycle process model. The quantitative analysis of the spatial and temporal evolution of vegetation and soil carbon sequestration values of various vegetation ecosystems in this region provide a scientific basis for the development of more scientific and rational carbon management measures. The research shows that the value of vegetation and soil carbon sequestration in the Qilian Mountains had increased from 2005 to 2015. The value of vegetation was 515.95×108 yuan， 491.05×108 yuan and 581.55×108 yuan in 2005， 2010 and 2015； the value of soil carbon sequestration was 356.56×108 yuan， 404.36×108 yuan and 465.65×108 yuan in 2005， 2010 and 2015. The change of land type has increased the soil and soil carbon sequestration by 12.72% and 30.39%， respectively. From the perspective of spatial distribution， the carbon sequestration in the eastern vegetation and soil is significantly higher than that in the west. The carbon sequestration capacity of the forest is the highest， and the carbon sequestration per unit area is 10.19 t·hm-2. Grassland is the most widely distributed vegetation in the study area， of which the contribution ratio to vegetation and soil carbon sequestration in this area is 51.13% and 49.34% respectively. |
