基于InVEST模型的窟野河流域碳储量变化对土地利用格局的响应
Response of carbon storage changes to land use pattern in Kuye River Basin based on InVEST model
摘要
Abstract
[Objective]Kuye River Basin is an important tributary of the Yellow River.Studying the impact of land use pattern on carbon storage changes is of great significance for maintaining regional ecosystem balance.[Methods]This study analyzed six phases of land use data using transfer matrix analysis,landscape pattern indices and the InVEST model to explore the synergistic relationship between land use pattern and carbon storage changes in Kuye River Basin.[Results](1)From 1997 to 2022,areas with high carbon storage were primarily located in the northern and southern regions of the study area.During the study period,the cold spot area increased significantly,indicating a decline in carbon storage,which decreased by 7.003×106 t.(2)From 1997 to 2022,the land use types in the study area were mainly grassland and cropland.Grassland area underwent substantial changes,decreasing by 498.47 km2,mainly converted to urban and rural areas,industrial and mining land,and residential land.Changes in landscape indices revealed a decline in grassland dominance,a weakening of risk resilience across various land use types,and an increase in landscape fragmentation.(3)From 1997 to 2022,the conversion of cropland,forest land,and grassland was identified as the primary cause of carbon storage reduction in the study area.The transition of grassland to urban and rural areas,industrial and mining land,and residential land resulted in the most severe carbon loss.The grey relational analysis showed a strong correlation between landscape pattern indices and carbon storage changes.[Conclusion]The carbon storage in the Kuye River Basin changes with the change of land use pattern.Forest land is most conducive to the increase of carbon storage.In the future,land use management should be strengthened,and the transformation of land use types such as grassland,cultivated land and forest land in the study area to urban and rural,industrial and mining,and residential land should be strictly controlled.关键词
