皖北粮食主产区生态系统服务权衡与协同作用强度及其驱动因素
Trade-offs and synergy intensity among ecosystem services and driving factors in main grain-producing areas of Northern Anhui Province
摘要
Abstract
[Objective]The strength and driving factors of trade-offs and synergies among different ecosystem services in major grain-producing areas were explored,in order to provide theoretical support and a decision-making basis for the management of regional ecosystem services.[Methods]Taking Northern Anhui Province as the research object,this study measured the five ecosystem services of water production,carbon storage,soil conservation,habitat quality,and grain productivity from 2000 to 2023,and used Moran's I to measure the spatial autocorrelation of each element.The dynamic ecosystem synergistic trade-off index was used to quantify the strength of the trade-off/synergistic relationships between the changes in each ecosystem service over a 23-year period,and an optimal parameters-based geographic detector was used to identify the driving forces of natural and social factors.[Results]① Over the past 23 years,the internal grain productivity service in Northern Anhui Province's grain-producing area has increased by 91.97％,whereas other ecosystem services have decreased.② The characteristics of the trade-off/synergistic relationships between ecosystem services are spatially heterogeneous;they are divided into four categories:strip-shaped,point-shaped,homogeneous,and scattered.The main supporting services have significantly influenced the spatial distribution of trade-off/synergistic relationships between different ecosystem services.③ The intensity of the ecosystem service trade-off/synergy is driven by natural factors(soil erosion power,NDVI).The interaction between natural and social factors also enhances spatial differences in trade-off synergy.[Conclusion]There is significant spatial heterogeneity in the synergistic effects of ecosystem service trade-offs in the main grain-producing areas of Northern Anhui Province.Natural factors are the chief driving factors,and the interaction between nature and society enhances spatial differences.关键词
