Abstract

A mismatch of water and land resources leads to various water problems and degradation of the ecological function of a basin. Existing water resource allocations and land resource allocations consist of different objects, basic units, allocation goals, and methods, and this makes it difficult to achieve joint allocations on a unified platform. In this study, we utilize the water and land resource system as the research object. An optimal allocation model of water and land resources is constructed, which utilizes multiple objectives from the aspects of water quantity, water quality, water efficiency, ecological function, and the matching degree of water and land resources. The constructed model is then used to allocate water and land resources in the Sihe River Basin, and the results of the water and land resource allocations of each configuration unit under different water supply conditions are obtained. This study provides technical support for a synthetically delicate management of water and land resources based on the land units in a river basin.
