By estimating the change in ecosystem service value before and after the implementation of land consolidation planning, it is able to quantitatively describe the change in ecosystem service value arising from land consolidation planning, so as to provide a quantitative basis for the environmental impact assessment of land consolidation. Taking the case of Anhui Province, the authors developed the equivalency factor table of ecosystem service value, to determine the economic value of single equivalency factor of ecological service value in the study area, calculate per unit area of ecological service value of land ecosystem in the study area, and research the change in ecosystem service value before and after the implementation of land consolidation planning in Anhui Province. The results show that after the implementation of a new round of land consolidation planning in Anhui Province, the total ecosystem service value may decrease to some extent, the farmland ecosystem service value substantially increases, while water body ecosystem service value greatly decreases.展开更多
