Trade-offs and synergies of ecosystem services in Yangtze River delta urban agglomeration:A spatiotemporally heterogeneous analysis approach
The Invest model was first employed to quantify the three ecosystem services,including habitat qualify,carbon storage,water conservation,in the Yangtze River Delta Urban Agglomeration.Then,the trade-offs and synergies of these three ecosystem services were explored.Finally,the spatially non-stationary relationships between ecosystem services and influential factors were examined using geographically weighted logistic regression.(1)two ecosystem services in the study area experienced a decline from 2000 t0 2020,with a decrease of 3.85％in habitat quality and a decrease of 0.51％in carbon storage,while water conservation underwent significant changes,with a large increase of 87.56％;(2)spatial heterogeneity was observed in the relationships among the three ecosystem services.Specifically,trade-offs were found between water conservation and habitat quality,as well as between water conservation and carbon storage,while synergies were observed between habitat quality and carbon storage;and(3)compared with other factors,the construction land area and the annual average temperature change exerted much stronger influence.In summary,the obvious spatial heterogeneity in both the trade-offs and synergies of ecosystem services and the influential factors was observed.
