Research on optimal allocation of water and land resources in the Yiluo River Basin, China

The allocation of water and land resources (WLRs) has adhered to a system where they "serve as boundaries for each other,"posing challenges in satisfying the exacting management requirements for these resources in the contemporary era. In line with precise predictions of the future WLRs, the optimal allocation framework of WLRs was constructed to obtain the rational configuration scheme. The prediction results showed that the imbalance between supply and demand of WLRs will intensify in the Yiluo River Basin. After configuration, the water shortage, water consumption, pollutant discharge, and soil erosion will be mitigated, and the ecosystem service function will be enhanced during the research period. It was proposed to enhance the WLR quality by strengthening the supply capacity, raising the utilization efficiency, reducing pollution, and safeguarding the ecological function. The research results will provide theoretical and technical references for the meticulous management of WLRs.
