Tradeoff‐Synergy Dynamics Between Ecosystem Service Values in Mine Ecological Restoration Based on Land Transfer Change

Exploring tradeoff‐synergy relationships between ecosystem service values (ESVs) is a key approach to evaluating the effectiveness of mine ecological restoration, which holds positive significance for harmonizing regional ecological management and human needs. Taking Dexing copper mine as the research area, based on revealing land transfer characteristics in the mine ecological restoration area, this study explores tradeoff‐synergy relationships between ESVs with different ecological functions. The results show that: (1) During the ecological restoration, the primary land transfer changes in the Dexing copper mine involved mutual conversions between forest and construction land and from construction land to cropland. The transition from construction land to cropland and forest exhibited distinct absolute and relative tendency patterns, respectively. (2) The ESVs in the Dexing copper mine showed a slight decrease at first and then a significant increase. The high ESV areas are mainly forest area and other types of ecological land, where no living, industrial, or mining activities have been conducted. The low ESV areas are mainly located in rural residential areas or mining areas and have remarkably decreased since 2018. (3) Synergy relationships dominated the interactions between different ecological functions of ESVs, while tradeoff relationships were observed only between FP and WRS. These findings provide foundational insights and references for ecosystem service management decisions in mine ecological restoration areas.
