Redundancy analysis identified the key factors affecting ecological benefits and their relative contributions.

The key factors affecting ecological benefits included pollution from mining and timber harvesting, which was strongly negatively correlated with restoration benefits (contributing 20.6%), and long-term restoration measures such as soil and water conservation, pollutant control, and river management, which contributed 71.6%.

However, many existing studies treated ecological water requirements as static baselines in allocation models, failing to address the dynamic utilization of water resources efficiently under varying hydrological conditions. In the Tao’er River Basin, a typical semiarid river basin, the combined effects of climate change and human activities have led to a severe imbalance between water supply and demand, particularly in regard to the competition between ecological water replenishment for the Xianghai Wetland, agricultural irrigation, and social water use. There is an urgent need for optimized water resource allocation to ensure the coordinated and sustainable development of these sectors. In this study, we developed the WEP-L model, a coupled natural–societal system, using various ecohydrological monitoring data to analyze the water supply–demand balance under different hydrological conditions. We proposed an allocation plan that considers ecological marginal benefits, agricultural needs, and water use guarantees: 1.04 × 10<sup>8</sup> m<sup>3</sup> for ecological supplementation and 5.16 × 10<sup>8</sup> m<sup>3</sup> for agricultural water in the flat year, adjusted to 0.94 × 10<sup>8</sup> m<sup>3</sup> and 3.60 × 10<sup>8</sup> m<sup>3</sup> in the dry year, respectively. Furthermore, by incorporating reservoir water supply rules into the WEP-L model, we simulated the feasibility of intra-annual water allocation. The proposed allocation scheme concentrates ecological water in spring during flat years and distributes it at a ratio of 80 % in spring and 20 % in autumn during dry years.
