以黄河下游生态脆弱区-济南南部山区为研究对象,基于区域1980~2020年6期土地利用/覆被数据,结合InVEST模型(Integrated Valuation of Ecosystem Services and Trade-offs model),分析区域土地利用/覆被和碳储量的时空分布特征和动态变...以黄河下游生态脆弱区-济南南部山区为研究对象,基于区域1980~2020年6期土地利用/覆被数据,结合InVEST模型(Integrated Valuation of Ecosystem Services and Trade-offs model),分析区域土地利用/覆被和碳储量的时空分布特征和动态变化规律,研究土地利用/覆被变化对陆地生态系统碳储量的影响.结果表明,土地利用/覆被变化对碳储量的影响较为显著,1980~2005年土地利用变化较小,人类活动影响较小,由于林草地碳储量的累积,碳储量增长速度明显高于其他时期;2005~2010年城市扩张速度最快,城乡建设用地大量侵占耕地、林地和草地,使区域固碳能力明显下降;2010~2020年,由于城市化扩张限制以及植树造林等生态保护措施的实施,区域碳储量逐渐呈增长趋势;1980~2020年济南南部山区的总碳储量呈“增长-下降-增长”的趋势;并且林地是济南南部山区碳储量的主要供给者,区域碳储量值随着远离城乡居民生活中心的距离增大而增大,说明人类活动对区域碳储量有重要的影响.另外,土地利用类型的转移引起地类碳密度的变化,是区域碳储量变化的主要影响因素,土地利用类型的碳储量变化与各地类的面积变化有一定的关系.该成果可为生态脆弱区塑造良好的陆地碳汇格局提供理论依据.展开更多
