Assessment of Carbon Emissions Based on Land Use Change in Northeast China
[Objective] Carbon emissions under different land utilization types in Northeast China region from 2000 to 2014 were analyzed to provide references for optimization of land utilization structure and reduction of carbon emission in Northeast China. [Methods] With the method of carbon emission coefficient
data of land use and energy consumption and other information were utilized to calculate carbon source/carbon sink under different land utilization types in Northeast China from 2000 to 2014 and to analyze regional differences and intensities of carbon emissions. [Results] (1) Construction land is the major source of carbon emissions in Southeast China
contributing to above 88% of the total carbon emission; Also the amount of Liaoning Province ranks the top. (2) Northeast China is rich in forest carbon-sink resources
and Heilongjiang Province is the major source for carbon absorption in Northeast China. (3) The per capita carbon emission intensity shows a slow-growth trend in Northeast China; The carbon emission intensity per area increases before reduction; The carbon emission intensity per unit GDP keeps decreasing stably
but the decline is insufficient for the reduction of total carbon emission. (4) Northeast China is an unbalanced area with Heilongjiang Province making contribution to other regions with respect to carbon absorption
the impacts of carbon emission in Jilin Province on ecological environment are assumed in an equliarated status by province wide itself; While Liaoning Province is over emitted at the expense of other regions. [Conclusion] Heilongjiang Province and Jilin Province are facing certain pressure of carbon emission reduction and Liaoning Province is facing relatively high pressure. Generally
Northeast China area is facing relatively high pressure for reducing carbon emission.
