Numerical models are the most convenient instruments to estimate net primary productivity (NPP) of terrestrial vegetation. Process-based Biome-BGC model has been widely used to simulate the storage and flux of water, carbon, and nitrogen within the vegetation, litter, and soil of terrestrial ecosystems. Some researchers used Biome-BGC directly to estimate NPP of the alpine meadow on the Qinghai-Tibet...
Rangeland protection and climate change prevention and adaptation share common goals. Rangeland protection funding should be used for climate change prevention and adaptation, and climate change countermeasures support sustainable development of Tibet. Tibet's rangelands account for about 69.1% of the total land area in the region. As one of the major terrestrial ecosystems, Rangelands resources play...
Vegetation is a basic component of urban-suburban landscapes, and turfgrass is a major vegetation type in U.S. cities. QuickBird images were acquired to map the spatial distribution of turfgrass, monitor vegetative conditions, and estimate carbon uptake. Shadows in the images were detected and removed by taking advantage of the high radiometric resolution of the QuickBird data. The results indicated...
Gross primary productivity (GPP) and Net primary productivity (NPP) are key components of the terrestrial carbon cycle. In this paper, an improved light utilization efficiency model was used to estimate GPP and NPP in East China from 2001 to 2008. This model included two sub models: GPP model and respiration model. The data input into the model including remote sensing data: MODIS production such...
