Multi-scale Study of Ecosystem Service Trade-off Collaboration and Ecosystem Service Bundle in Harbin City
This paper analyzes the variable and complex interactions between ecosystem services,and provides a reference for the formulation of multi-scale regional planning and ecosystem manage-ment strategies in Harbin.The ecosystem services for three periods from 2010 to 2020 were calculat-ed,and the ecosystem service correlation and spatial correlation were calculated at the grid,town-ship,district and county scales,and finally the ecosystem service clusters at the three scales were calculated.The results showed that:1)The spatial pattern of the ecosystem was basically stable in the three periods from 2010 to 2020.The maximum value of carbon sequestration in forest land de-creased from 7.43 t to 5.13 t in 2020,and the water yield was closely related to precipitation,which was as low as 483.9 mm in 2015.2)The trade-off synergies of ecosystem services changed with time and scale.6 pairs of ecosystem services showed synergistic effects,five of which showed synergistic effects with the increase of scale.Another six pairs of ecosystem services showed trade-off effects,and the trade-off effects changed at the township scale.3)There were differences in e-cosystem service clusters at the three scales,while the ecological comprehensive clusters and wood-land synergy clusters were similar at the three scales,reflecting the regional characteristics of differ-ent scales,which could provide a basis for multi-scale management.
