黄土高原丘陵沟壑区坡耕地撂荒后自然恢复草地碳动态
发布时间：2021-06-29 09:33
黄土高原大规模的退耕还林还草促进了生态恢复。但是长期来看,树种的生长消耗土壤水分,致使土壤表层形成了干化层,最终导致林地退化。自然植被演替表现出越来越强的生态适应性,加速自然植被的演替可以加速生态恢复。本研究以黄土高原自然恢复草地为研究对象,通过野外调查和实验室分析,选取典型样地对植被和土壤碳库变化动态进行了研究,提出了加速草地恢复和增加土壤碳汇的对策和措施。本研究为自然草种演替增加土壤碳汇、恢复生态环境提供了重要的科学依据。本研究取得的主要结论如下:（1）草地恢复加强了土壤碳库的积累,包括土壤有机碳库和无机碳库,但是这两个碳库在总碳库的占比相反。与农田相比,土壤有机碳储量（0-100 cm）在草地恢复的早期显著降低,土壤无机碳储量（0-100 cm）在农田撂荒后早期显著增加。土壤无机碳储量恢复较之有机碳储量恢复快。与农田相比,0-100cm土层土壤有机碳储量增量分别为-0.039（5年）,0.037（13年）,0.840（24年）和1.082 kg m-2（32年）;0-100cm土层土壤无机碳储量增量分别为1.209（5年）,6.000（13年）,6.608（24年）,and 4....
