Analysis on Trade-offs and Synergies of Ecosystem Services in the Pingshuo Mining Area
Understanding the trade-offs and synergies between the ecosystem services has great significance on realizing ecological protection and soc-economic development.In this paper,the trade-offs and synergies be-tween ecosystem services in Pingshuo mining area from 1990 to 2020 were quantitatively analyzed by using the standard equivalent method and the ecosystem services trade-off degree.The results showed that:(1)the total of ecosystem service value decreased by 3 806.96 × 104 CNY during 1990 and 2020,among which,water conserva-tion value presented the largest decrease(2 091.01 × 104 CNY).(2)The relationship between ecosystem serv-ices in the Pingshuo mining area as a while was mainly synergetic(80.25％)from 1990 to 2020.The degree of synergy between water conservation and other ecosystem services was the biggest,while the degree of trade-off between soil conservation and other ecosystem services was the biggest.Quantitative assessment on trade-offs and synergies of ecosystem services is helpful for scientific ecological management and maximizing ecological benefits in mining area.
