Land Use Function Transition and Associated Ecosystem Service Value Effects Based on Production–Living–Ecological Space: A Case Study in the Three Gorges Reservoir Area

The transition of land use function and its effects on ecosystem services is a key issue in eco-environmental protection the basis territorial space governance optimization. Previous studies have typically selected types to evaluate service value (ESV) overlooked comprehensive characteristics mutual feedback relationship between human social systems ecosystem. Taking Three Gorges Reservoir Area, Hubei section (TGRA-HS) as case study, we used matrix, revised ESV method, an ecological contribution rate model explore (LUFT) change based production–living–ecological (PLES) classification system. results show that: (1) PLES was mapping evolution human–nature spatial pattern, which reflected pattern caused by interference with continuous development society; (2) showed reduction production (P-space), expansion living (L-space) (E-space). distribution from 1990 2020 basically same, structural transform project construction different phases; (3) E-space contributed most total ESV, it has risen CNY 13.06 × 108. projects impacts spatiotemporal regional ESV; (4) induced LUFT revealed whole dynamic process positive negative services, two offset each other keep relatively stable. P-space had greatest impact whose 82.76%. changes corresponding stages Project’s (TGP) reveals important driving effect activities services. It reminds us that humans should not forget protect eco-environment when obtaining
