| 摘 要： | 政策总是通过对土地利用/土地覆被的强烈影响而影响陆地碳平衡。本研究旨在探讨环境保护政策（主要是退耕还林）政策对我国陆地碳平衡的影响,从而为政府部门等相关政策制定者提供环境保护和应对气候变化的决策支持。利用DLS（Dynamics Land System）模型对2000-2025年环境保护政策情景下的土地利用变化模拟结果和前人对碳密度的研究成果,运用碳密度法估算了该政策情景对中国陆地碳储量的影响。研究结果表明,在整个阶段,林地将增加23%,耕地和草地将分别减少37%和11%,由此会引起我国森林碳储量每年增加66.0 Tg C,土壤碳储量每年增加13.3 Tg C,而草地碳储量则每年减少5.7 Tg C。总体而言,在环境保护政策情景下,2000-2025年中国整个陆地生态系统的碳储量将增加1.8 Pg C,年均增加量为0.074 Pg C,而这种变化89.6%的原因源于森林碳储量的增加。

| Abstract: | Policies always have strong impacts on land-use and land-cover change (LUCC),and thus indirectly affect the terrestrial carbon balance.In this paper,land use change from 2010 to 2025 in China was simulated with the Dynamics Land System (DLS) under an environmental conservation policy scenario,and the projected effect of this policy scenario on Chinese terrestrial carbon storage was evaluated.Under the simulation,forest coverage will increase by 23% while cropland and grassland will decrease by 37% and 11% r... |
