摘要
应用InVEST模型(生态系统服务和权衡的综合评估模型)对太原市六城区2000—2020年碳储量变化进行测算,基于2000、 2005、 2010、 2015、 2020年5期土地利用数据,探讨土地利用变化对碳储量的影响,为城市空间优化和生态安全格局构建提供参考。结果表明:20年间,太原市六城区除草地面积下降14.26%外,其他5类土地利用类型面积均呈增长态势;总体碳储量、土壤碳和死亡有机碳均呈不断下降趋势,地上和地下碳储量呈不断上升趋势;仅万柏林区碳储量在研究末期(2020年)比研究初期(2000年)增加0.6%,其他5个城区均出现不同程度的下降。
Using the InVEST(Integrated Valuation of Ecosystem Services and Trade-offs)model,the carbon storage changes in six urban districts,Taiyuan City from 2000 to 2020 were calculated.Based on five periods of land use data from 2000,2005,2010,2015,and 2020,the impact of land use changes on carbon storage was explored,providing reference for urban spatial optimization and ecological security pattern construction.The results show that over the past 20 years,except for a 14.26%decrease in grassland area,the area of the other 5 types of land use in the six urban districts of Taiyuan City shows an increasing trend;the overall carbon storage,soil carbon,and dead organic carbon all show a continuous downward trend,while the aboveground and underground carbon storage shows a continuous upward trend;only the carbon storage of Wanbailin District increased by 0.6%in the late stage of the study(2020)compared to the early stage of the study(2000),while the other five urban areas showed varying degrees of decline.
