Impacts of land use/cover changes on carbon storage in Beijing 1990-2010

摘要

According to the data sets of land use/land cover (LULC) in 1990, 1995, 2000, 2005 and 2010, and carbon pools of each LULC category, we estimated the carbon storage of Beijing and each district from 1990 to 2010 by In VEST model. The results indicate that the carbon storage of Beijing ranged from 1.29 × 10~8 t C to 1.23 × 10~8 t C over the last 20 years, and decreased 5.6 × 10~6 t C. The carbon storage is mainly located in suburbs. The cropland turned into construction land causes the continual depletion of carbon storage, which is accompanied by continual urbanization.
