Spatio-temporal Change of Ecosystem Service Value and Its Driving Factors in Xiaoshui River Basin
The calculation of ecosystem service value(ESV)in specific river basin is of great significance to promote the construction of ecological civilization and sustainable development.Taking Xiaoshui River basin,the source of Xiangjiang River,as the example area,it analyzes the spatio-temporal dynamic characteristics of ESV in Xiaoshui River basin by the means of the equivalent factor method of correction coefficient,the spatial autocorrelation analysis,the geographic detector and other methods,and explores the interaction mechanism of the leading factors and driving factors of ESV spatial differentiation based on land use data in 2010,2015,2020.The results showed that:1)The ESV of Xiaoshui River basin decreased from 2010 to 2015,and increased from 2015 to 2020.2)The high-value areas of ESV are linearly distributed along Xiaoshui River,and its spatial distribution showed obvious spatial clustering,which tends to weaken gradually.3)The spatial differentiation of ESV in Xiaoshui River basin is influenced by the coupling of natural and socio-economic factors,among which the human impact index has the greatest influence on the spatial differentiation of ESV.
