The Carbon Sink Estimation and Carbon Sink Increase Potential of Jiangmen, China

The sequestration of forest, farmland, and Green garden carbon inJiangmen City during 2004 to 2010 has been estimated. The biggest carbon sink in 2010 is the forest, with an annual carbon sequestration of ; next is the farmland, with an annual carbon sequestration of . The C uptaken by these two types of carbon sinks accounts for 95% of all the carbon sinks in Jiangmen City. Potentials for the increase of carbon sinks are then discussed. To popularize growing green manure during winter may increase carbon sequestration at about every year. If all the newly established open forests in the whole City in 2010 are fenced for forest conservation, an annual carbon sequestration of may be expected to increase in two years. If the per mu yield of crops below the average of Guangdong Province in 2010 are increased to the average, an annual carbon sequestration of may increase.
