Abstract:Ecological protection and restoration of mountain, river, forest, farmland, lake, and grassland are important parts of ecological civilization construction. This paper combines the evaluation of ecosystem services with ecological protection and restoration projects. Taking the third batch of national pilot projects of ecological protection and restoration of mountain, river, forest, farmland, lake, and grassland in Heshan District of South Taihang of Henan Province as an example, it explores the application of ecosystem service evaluation to ecological protection and restoration.The results show that the ecosystem service value of Heshan District has declined and the ecological environment has been seriously damaged in recent years. From 2014 to 2017, the ecosystem service value of secondary services for different land types in Heshan District decreased by 3039500 yuan. During the research period, the value of eight ecological services declined by varying degrees, including supply of water resources, gas regulation, climate regulation, purification environment, hydrological regulation, soil conservation, biodiversity, and aesthetic landscape. The results of this study on ecological protection and restoration in Heshan District indicate that attention should be paid to the service functions of hydrological regulation, purification environment, soil conservation, and ecosystem biodiversity. Ecological protection and restoration projects should focus on river ecological restoration and wetland protection, mine ecological environment restoration and land reclamation, forest and biodiversity conservation and restoration; mountains-rivers-forests-farmlands-lakes-grasslands ecological protection and restoration projects in Heshan District can enhance the value of regional ecological services. Among them, the total value of ecosystem services after implementation is expected to reach 364079500 yuan, an increase of 77419600 yuan over 2017, representing a growth rate of 27% and improved value of various ecosystem services. These results will play a guiding role in the implementation of ecological protection and restoration projects of mountains-rivers-forests-farmlands-lakes-grasslands in Heshan District.
