Multi-scenario assessment of ecosystem service value in resource-exhausted city
Taking Xuzhou City,a resource-exhausted city,as the research object,the land use pattern under different sce-nario in 2025 and 2030 was predicted by coupling the MOP-PLUS model based on 5 periods of land use data.Based on the land use prediction data,the Equivalent Factor Method was used to quantify the ESV ecosystem service value of Xuzhou City.The results showed that(1)the decline of ESV in Xuzhou City gradually slowed down during the period of 2000-2030,presenting a better ecological protection trend.(2)The ESV of Xuzhou City featured a spatially intertwined distribu-tion of high and low values,with a high degree of overlap of nine services.(3)During the past 21 years,in Xuzhou City a sustainable development policy has been adopted that takes into account both ecology and economy,and the nine services have developed in a highly coordinated manner.However,urban construction tends to be saturated,and in the future,it is necessary to keep the construction land area within 3135.83 km2.
