The Effect of Integrated Protection and Restoration of Landscape,Forest,Lake,Grass and Sand on Ecosystem Service Value from the Perspective of Land Use and Land Cover Change
The integrated protection and restoration of landscape,forest,Lake,grass and sand plays an important role in improving the quality of the ecological environment and achieving the goal of ecological civilization in the new era.Quantitative measurement of the ecological benefits it brings has gradually become a difficult and hot topic in this research.Therefore,taking the key project area of landscape engineering in Linyi city as the research area,based on land use change,a value evaluation method is established and the impact of landscape engineering implementation on ecosystem service value is explored.From 2020 to 2023,the total value of ecosystem services in the study area will be 12.135 17 billion yuan and 12.344 18 billion yuan respectively,with an overall increase of 209.01 million yuan.Cultivated land accounts for a larger area,which results in a higher proportion of its ecosystem service value in the total amount,but woodland and watersheds,with a relatively smaller area,contribute to about 50%of the ecosystem service value.However,the changes in the area of forest land and watershed will have a greater impact on the overall ecosystem service value of the region.This study is useful for assessing the ecological performance of the Shanshui project,establishing a long-term mechanism for ecological protection,and continuously improving ecosystem services.
