Global warming has intensified extreme weather events, posing challenges to regional climate and hydro-ecological systems. To address the low-resolution limitations of current multi-climate variables potential evapotranspiration (PET), this study develops a super-resolution fusion framework based on deep residual attention mechanisms, establishing China's 10-km resolution multi-model-multi-scenario high-resolution PET dataset (SRCPCN10). The Residual Channel Attention Network (RCAN) demonstrates exceptional downscaling performance for temperature, radiation, pressure (R2/KGE > 0.99), while precipitation exhibits significantly lower accuracy (R2 = 0.897) due spatial discontinuity. findings reveal distinct emission-gradient responses in future under SSP scenarios, with increases escalating alongside radiative forcing intensification. comparison annual mean differences between original CMIP6 downscaled data showed excellent agreement, most indices differing by less than 1%. This work overcomes traditional limitations, providing kilometer-scale multivariate watershed hydrological modeling, agricultural risk assessment, carbon-neutral pathway optimization, enhancing precision adaptation strategies.

Identifying ecological functional areas by clarifying the trade-off synergies of multiple ecosystem services to meet practical needs coordinating different in a specific region is highly important. Based on InVEST, RUSLE and other models, this study analyzed tradeoff five typical Wanjiang Urban Belt from 1990 2020 using Pearson correlation analysis, self-organizing map (SOM) carried out zoning. The PLUS model was used simulate evolution zones 2030. results revealed that (1) 2020, water yield (WY), soil reservation (SR), food production (FP) increased, whereas carbon storage (CS) habitat quality (HQ) decreased. value showed pattern “high south low north”. (2) WY–SR, WY–HQ, HQ–CS, HQ–SR were synergistic, synergistic relationship weakening trend. There trade-offs WY–CS, WY–FP, SR–FP, effects increased with time. (3) area divided into an transition area, conservation urban development restoration agroecological functions structures each cluster significantly differed. (4) Under natural scenario, scales transition, conservation, increased. cropland protection began transform areas. transfer restoration, In conclusion, are dominated effects, but there potential risk shifting relationships. future, targeted regional optimization measures according status zone urgently needed provide references for territorial space management control region.

Understanding the spatial differentiation of ecosystem service (ES) interactions and their underlying driving mechanisms is crucial for effective management enhancing regional landscape sustainability. However, comprehensive analyses effects key influencing factors on ES remains limited, especially regarding nonlinear heterogeneity. We assessed validated five in National Key Ecological Function Zones (NKEFZs) China—net primary productivity (NPP), soil conservation (SC), sandstorm prevention (SP), water retention (WR), biodiversity maintenance (BM). By integrating optimal parameter geographical detector with constraint line methods, we further explored complex responses to across different functional zones. The results showed that most exhibited significant synergistic clustering. In contrast, widespread trade-off clustering was detected pairs related WR, mainly distributed Tibetan Plateau, northeast China, Southern Hills region. Due improvement ES, overall synergies enhanced from 2000 2020. dominant zones influenced a non-stationary manner, same potentially showing diverse effect types sub-regions. Additionally, role configuration sub-regions specific interaction (e.g., WR-NPP SP zones), suggesting potential achieving multi-ES through planning without altering composition. This research provides valuable insights into understanding offers scientific foundation implementation ecological protection restoration plans.
