Abstract:
Exploring the multi-scale evolution characteristics of ecosystem service value (ESV) and its intrinsic mechanism is the basis for the construction of cross-scale ecological security pattern. Based on multi-source data such as NDVI and POPD, combined with spatio-temporal geographically weighted regression and other methods, a multi-scale research framework was constructed to systematically reveal the spatial and temporal evolution of ESV and its influence mechanisms from 2000 to 2020 in Suzhou City. The results showed that: ① ESV showed "W-shaped" fluctuating changes, a small overall decline, a more prominent spatial aggregation at each grid scale, and a weakening trend in the increase at the grid scale. ② The natural and social factors tended to be stronger over time, and the role of landscape pattern factors fluctuating changed, of which the natural factor NPP force in each scale was always dominant. ③ The spatial distribution of the influence of factors showed an increase in scale from polarization to equilibrium, and the magnitude of change was weakening. The force of natural and social factors tended to be stronger with time, and the role of landscape pattern factors fluctuated, of which the force of natural factors NPP always dominated at all scales. The correlation law can deepen the theory of ESV multiscale impact mechanism, which can provide scientific basis for optimizing the structure of multilevel regional ecosystems and formulating multiscale ecosystem management decisions.
