Spatiotemporal variations and tradeoffs as well as synergies of ecosystem services in Xiaoluan River Basin
[Background]The interactions and spatiotemporal and characteristics of ecosystem services are crucial for maintaining human well-being and achieving regional sustainable development.[Methods]Based on InVEST model,the revised universal soil loss equation(RUSLE)and RD A analysis,this paper systematically evaluated four important ecosystem services in the Xiaoluan River Basin,and identified the trade-offs/synergies of ecosystem services and their driving factors.[Results]1)Forest land and grassland had the highest habitat quality,with forest land showing significant advantages in soil conservation and water retention services,while cultivated land having a strong capacity for water purification services.2)From 2000 to 2020,the habitat quality,water retention and water purification in the Xiaoluan River Basin showed an increasing trend,and the relationship between soil conservation and water purification services changed from a synergistic relationship to a tradeoff relationship,while the relationship between soil conservation and water purification services showed a gradually enhanced synergistic relationship.3)Ecosystem services are influenced by multiple factors.Precipitation,NDVI and forest land proportion have positive effects on water retention,soil conservation and habitat quality services,but negative effects on water purification services.[Conclusions]The Xiaoluan River Basin should comprehensively consider the situation of ecosystem services and economic development,and continuously adjust the land use planning according to the actual situation.The results provide scientific guidance for formulating reasonable ecosystem management measures locally.
