| In this paper, the comprehensive ecological, economic and social benefits of ecological restoration
of sandy land in Naiman Banner were evaluated by market substitution method. Based on the ecological,
social and economic data of Naiman Banner from 2001 to 2021, the comprehensive benefit evaluation
system of ecological restoration of sandy land in Naiman Banner was constructed. The comprehensive
benefit value law was studied, and the coupling degree and coupling coordination degree among ecological
benefit, social benefit and economic benefit were analyzed. The results showed that from the perspective
of benefit value, the value of ecological benefit subsystem, social benefit subsystem and economic benefit subsystem of ecological restoration showed an overall rising trend from 2001 to 2021, and the
total value of comprehensive benefit increased by about 5 billion yuan. From the perspective of coupling
degree, the coupling degree C value increased from 0. 257 in 2001 to 0. 942 in 2021. The change of coupling
type was low level coupling stage in 2001, antagonism stage in 2002, running-in stage from 2003 to
2008, and high level coupling stage from 2009 to 2021. From the perspective of coupling coordination
degree, the coupling coordination degree D value increased from 0. 091 in 2001 to 0. 887 in 2021. The
corresponding change of coupling coordination degree was the stage of imbalance and recession among ecological,
social and economic benefit subsystems from 2001 to 2007, the stage of extreme imbalance in
2001, the stage of towards recession in 2008, the stage of coordinated development from 2009 to 2021,
and the stage of good coordination in 2021. |
