英文摘要: Large-scale afforestation is a primary tool for combatting desertification and global warming. However, the consequences for future ecosystems are complex and poorly understood. To judge the payback from afforestation in arid regions, we assessed the effects of the Three-North Shelter Forest Program, which is the world's largest ecological restoration program, in predominantly semi-arid to arid regions in China. Our analysis revealed a net loss of 230.8 × 109 RMB annually for afforestation, suggesting that tree planting is a poor choice in much of northern China. However, establishment of fruit tree plantations and protecting vegetation to allow natural recovery produced large annual benefits (235.5 × 109 RMB and 447.43 × 109 RMB, respectively) due to having the highest product value and lowest restoration cost, respectively. Because the net benefits were negative for artificial afforestation, and some net benefits were negative for some restoration programs in some regions, it is essential to change the proportions of the different restoration methods both to improve the restoration success and ensure the survival of the residents in areas affected by the program. © 2020 Elsevier Ltd Citation statistics:
