As the U.S. and the International Community come to grips with anthropogenic climate change, it will be necessary to develop accurate techniques with global span for remote measurement of emissions and uptake of greenhouse gases (GHGs), with special emphasis on carbon dioxide. Presently, techniques exist for in situ and local remote measurements. The first steps towards expansion of these techniques...
Terrestrial ecosystem carbon cycle plays an important role in global carbon cycle because of its complexity and uncertainty. Study on terrestrial ecosystem carbon cycle relates to global climate change and potential ways or means to address. This paper is attempting to provide an overview of mechanism and research method of terrestrial ecosystem carbon cycle and perspective of emphases and hotspots...
In order to evaluate the impact of urbanization on carbon cycle, we selected the Beijing city as the study area to estimate CO2 emission both from anthropogenic activity and natural processes. The spatial pattern of annual CO2 emission in 1992 and 2005 in Beijing city was estimated by using the socio-economic statistical data, remote sensing data and GIS-based approach. The main factors include transport,...
Based on the STIRPAT model and spatial autoregressive models, this paper investigates the energy-related CO2 emissions of 30 provinces in China from 2000 to 2006 and the underlying driving forces. The result shows that there exists spatial interdependence of the provincial CO2 emission, and the energy intensity, population growth and economic development level are the main contributors to CO2 emissions,...
