Spatiotemporal Changes in the Supply and Demand of Ecosystem Services in China’s Huai River Basin and Their Influencing Factors

An imbalance between the supply and demand of ecosystem services can cause ecological problems. By determining spatiotemporal changes in factors underlying these changes, service river basins be increased to match demand; this information has great significance for sustainable development basin. focusing on cities China’s Huai River Basin, data from 2010 2020 were measured using supply–demand matrices, characteristics balance analyzed index Moran’s I statistics. Next, geographical detectors multiscale geographically weighted regression models used examine influencing their spatial effects. The results indicated following: (1) From 2020, Basin decreased by 2.51 × 108, whereas 4.43 108; general, exceeded supply, 69.74% a state deficit. (2) was greater than 0.4, which means that there strong clustering, high–high clusters gradually weakened those low–low enhanced northern eastern cities. (3) q values ecological-use land area, construction-use rain, temperature 0.3, indicating significant effect demand. These findings provide targeted reference basis management Basin.
