  "abstract": "目的凋落物碳水化合物组成对黄土高原人工林土壤碳储量具有显著影响，但该区域在水热梯度变化下，人工林乔灌草碳水化合物组成的空间分布及其对凋落物碳水化合物储量的影响尚不明确。方法对比了黄土高原3个植被带刺槐人工林乔灌草各器官（叶、枝、根）非结构性碳水化合物（NSC）与结构性碳水化合物（SC）的储量差异，并分析其对地上凋落物碳水化合物储量的影响。结果各植被带刺槐人工林碳水化合物储量以乔木层为主导，贡献比例达92%。乔灌草碳水化合物组成均以SC为主，但灌草SC储量仅为乔木的3%~8%。人工林地下碳水化合物储量显著高于地上，其中乔木和灌木的地上碳水化合物储量均随水热条件改善而显著增加，地下部分仅乔木SC储量和灌木NSC储量呈显著增加趋势。不同植被带对比表明，草原区受水分胁迫限制，碳水化合物总储量最低，森林草原区储量显著提升，森林区在水热与土壤养分协同作用下，碳水化合物总储量达到最高水平。草本地上NSC及乔灌草地上SC储量是驱动不同植被带地上凋落物碳水化合物储量变化的关键因子，可显著促进表层土壤有机碳的积累。结论水热梯度可通过调控乔灌草碳水化合物分配策略，改变凋落物碳输入结构，进而调控土壤有机碳积累。",
