[Spatial and Temporal Evolution of Ecosystem Service Supply and Demand and Analysis of Driving Factors in Chongqing Based on InVEST Model and XGBoost-SHAP].

of the ratio of ecosystem services supply to demand in 2000, 2010, and 2020 were 0.674, 0.666, and 0.679, respectively, with significant positive correlation in the space. The distribution characteristics were dominated by high-high aggregation and low-low aggregation, with high-high aggregation concentrated in the ecological barrier areas such as Chengkou County and Nanchuan District and low-low aggregation concentrated in the urbanization core areas such as Yuzhong District and Shapingba District. ④The XGBoost-SHAP model indicated that precipitation, urbanization rate, industrial output value, and the proportion of agricultural output value were the key driving factors influencing the relationship between supply and demand. The results can provide scientific references for regional ecological protection, ecological zoning control, and sustainable development.
