摘要
土地利用变化显著影响着陆地生态系统碳储量。明确二者之间的关系对区域生态碳储量提升以及“双碳”目标的实现有着十分重要的意义。研究基于山西省2000—2020年的土地利用数据,耦合PLUS和InVEST模型,并分别设置自然发展、经济建设与生态保护三种情景,模拟预测山西省2020—2030年土地利用及碳储量变化。结果表明:2000—2020年山西省土地利用格局以耕地、林地和草地为主,耕地、草地、水域及未利用地减少,林地与建设用地增加,总碳储量呈下降趋势。2020—2030年模拟预测结果显示,生态保护情景下碳储量上升显著,而经济建设情景与自然发展情景下降明显,尤其是经济建设情景。研究成果为山西省践行“双碳”目标提供理论支撑,促进区域生态系统稳定与绿色低碳发展。
Land use changes significantly impact the carbon storage of terrestrial ecosystems.Understanding the relationship between the two is crucial for enhancing regional ecological carbon storage and achieving the“dual carbon”goals.This study is based on land use data from 2000 to 2020 in Shanxi Province,coupling the PLUS and InVEST models,and setting three scenarios:natural development,economic construction,and ecological protection,to simulate and predict changes in land use and carbon storage in Shanxi Province from 2020 to 2030.The results indicate that from 2000 to 2020,the land use pattern in Shanxi Province was primarily composed of arable land,forest land,and grassland,with reductions in arable land,grassland,water bodies,and unused land,while forest land and built-up areas increased,leading to a decline in total carbon storage.The simulated predictions for 2020 to 2030 show a significant increase in carbon storage under the ecological protection scenario,while the economic construction and natural development scenarios indicate a noticeable decline,particularly in the economic construction scenario.The research findings provide theoretical support for Shanxi Province in implementing the“dual carbon”goals,promoting regional ecosystem stability and green low-carbon development.
