Abstract:
IPCC method was adopted to study the dynamic variation of carbon source and carbon sink in Shandong province. Conclusions are as follows:carbon source increased from 59 456.08×104t to 144 961.60×104 t year by year in Shandong province from 2000 to 2010，with an annual growth rate of 13.07%; Besides, carbon source per capita increased from 6.61 t to 15.13 t. Carbon source per unit area increased form 37.68 t/hm2 to 91.86 t/hm2, and then carbon source per ten thousand Yuan GDP dropped from 3.63 t to 2.88 t, which showed continuous improvement of energy utilization. During the same period, carbon sink dropped from 4 519.03×104 t to 4 230.18×104 t, decreased by 6.4%. At the same time, carbon sink per capita fell from 0.50 t to 0.44 t,and carbon sink per unit area decreased from 2.86 t/hm2 to 2.68 t/hm2. Because the carbon source is larger than the carbon sink, the net carbon source increased from 54 937.05×104t to 140 731.42×104 t, reaching a growth rate of 156.17%. Accordingly, the net carbon source per capita in Shandong province is 3~7 times higher than the goal of global climate change, as well as higher than the average of China, and yet a little lower than that of the United States only. Furthermore, the net carbon source per unit area is 31.08~79.63 times higher than the goal of global climate changes, too. The results show that it is a carbon sink from a view of overall external performance in Shandong province, facing a very difficult task of carbon emission reduction. In terms of the driving factors of continual carbon increased resource, it is mainly due to the high proportion of secondary industry in the industry structure, as well as the high carbon characteristics of industry system. Besides, high-carbon energy such as the coal accounts for a large proportion of energy consumption structure, making up another driving factor for continual carbon resource.
