Abstract:

In order to understand the carbon sequestration capacity of forests in Liaoning Province, the carbon storage and carbon density of arboreal forest were studied based on the national data of forest resources. The carbon characteristic values were estimated and compared among different forest age groups and forest species, then the carbon sequestration capacity of forest resources in Liaoning was analyzed. The results show that: among the shelter forests, the weight of carbon storage is the largest in middle-aged forest and the weight of area is the largest in young forest; among the special use forests, the mature forest has the largest carbon storage weight and the largest area weight; among the timber forests, the carbon storage weight of middle-aged forest is the largest and the area weight of young forest is the largest; among the firewood forests, both the carbon storage weight and the area weight of young forest are the largest; and the shelter forests have the highest carbon storage in young forest, middle-aged forest, near-mature forest, mature forest and over-mature forest. The study can provide data support for forest management and environmental protection.
