Abstract: According to the requirements of afforestation for carbon sink,an evaluation system was established that was based on an analysis of forest carbon sink estimation,ecological importance,economic and social situation,and potential risks for the selected plots.And analysis was made of afforestation selected plots for launching forest carbon sink projects in Sichuan.The selected plots were divided into the priority area,the sub-priority area and the potential area.Each area was 418 800 hm²,343 500 hm² and 290 400 hm²,accounting for 36.0%,29.6% and 25.0% respectively of the area for afforestation in Sichuan.In this study,the major priority areas for forest carbon sink projects in Sichuan were mainly distributed in the Qinba Mountain area in the northwest of Sichuan and the Liangshan area in the southwest of Sichuan.
