Interaction between rapid urban expansion and ecosystem service value trade-off/synergy in Wuhan City
Studying the interrelationships and drivers of various ecosystem services in rapidly expanding urb-an areas is important for coordinating the sustainable development of regional society,economy,and ecology.Taking Wuhan City,which is in the process of rapid urbanisation,as an example,we analyse the spatial differ-entiation characteristics,trade-offs/synergies,and multiple factor interactions of the values of 11 ecosystem ser-vices in the study area based on multi-source data.The results showed that:1)The urbanisation rate of Wuhan City increased by 25.43％from 2000 to 2020,and the land use structure changed significantly,among which the area of construction land increased the most,by 25.86％,and the area of lakes and arable land decreased significantly.2)The total value of ecosystem services in Wuhan City shows a decreasing trend,decreasing by 670 million yuan,regulating services dominate,reaching more than 65.75％of the total,of which the total value of hydrological regulating services is the highest,mainly originating from lakes.3)The relationship between 11 ecosystem services in Wuhan City from 2000 to 2020 was dominated by synergistic relationship,accounting for 80.00％,and the trade-off relationship mainly existed between food production and other ser-vices.4)The results of the geodetector showed that socio-economic factors explained the spatial differenti-ation of ecosystem service values more than natural factors,and the per capita net income of rural households,food production,and population density had the greatest intensity of influence.
