Ecosystem Service Trade-offs and Synergies in Yumen City
摘要
Abstract
[Objective]To explore the trade-off and synergy among ecosystem services in Yumen City,and to provide a scientific basis for the construction of ecological security barriers and sustainable development in the region.[Method]Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST)model was used to quantify three kinds of ecosystem services(carbon sequestration,habitat quality and soil conserva-tion),and partial correlation analysis was used to explore the trade-offs and collaborative relationships among ecosystem services.[Result]The results showed that:during the study period,the main land use types in Yumen City were unused land and grassland,the land-use conversion mainly concentrated in forest land and unused land.The carbon sequestration and soil conservation showed an upward trend,the whole area of habitat quality was low and stable.The main contributions of ecosystem services were cropland,forest land and grassland.The ecosystem serv-ices are mainly synergistic under the different spatial scale.[Conclusion]The trade-offs and synergies of ecosystem services had spatial hetero-geneity in Yumen City,and the impact of land use change on ecosystem services should be strengthened in the future.关键词
