Multiple Scenario Simulation of Ecosystem Service Value in Xuzhou City Based on PLUS Model
The purposes of this study are to analyze the changes of ecosystem service values(ESV)in Xuzhou City in the year of 2000 to 2020,to evaluate the values of ecosystem services in Xuzhou City under multiple scenarios,and to provide the reference for the transformation and development of resource-based cities.The research methods of land use dynamic change,equivalent factor evaluation and PLUS model are used.The results show that:1)the land use type of Xuzhou City is dominated by rural land and construction land,with the area of rural land decreasing continuously from 2000 to 2020,and the area of wetland and water decreasing first and then increasing.2)From 2000 to 2020,the ESV of Xuzhou City decreased first and then increased.3)In the three land use scenarios of natural development,urban development and ecological protection,the different kinds of ESV loss occurred.The mediation service value showed the greatest loss.The decrease of cultivated land and grassland area contributed significantly to of the ESV loss.The declining trend of ESV was the most obvious in the urban development scenario,due to the accelerating expansion of construction land.The ESV loss was the least in the ecological protection scenario.In conclusion,the resource-based cities should continue to balance economic development and ecological protection,and should strengthen the function of the planning to lead ecological restoration and promote the green transformation and upgrading of resource-depleted cities.
