Dynamics of Carbon Storage and Its Drivers in Guangdong Province from 1979 to 2012

Accurately estimating the carbon storage of forest ecosystems and deriving the driving factors affecting forest carbon storage are the prerequisites and foundations for promoting the development of global carbon sinks. In order to explore an effective approach for monitoring the carbon sink of fores...
