Ecological balance model of effective utilization of agricultural water resources based on fractional differential equations

Water is a key factor that controls the evolution of the ecosystem and restricts social and economic development. The rational allocation of water resources is the basis for the basin's sustainable use of water resources. The article uses fractional differential equations to discuss the increasingly prominent contradictions between supply and demand of agricultural water resources, serious pollution and overexploitation, the decline in groundwater level and water quality, low agricultural water efficiency, and serious waste from the perspective of sustainable development. Second, the article classifies the index system of the water resources carrying capacity evaluation model. Finally, model the resource balance of water supply and water demand in the irrigation area. The study found that the water quantity analysis and determination of the irrigation area will have important guiding significance for implementing the irrigation area's continued construction and water-saving transformation. The allocation and utilization of water resources in farmland irrigation areas will tend to be rationalized. This will greatly improve the water-saving efficiency of irrigation districts.

Automated summary

This article discusses the importance of rational allocation and utilization of water resources for the evolution of the ecosystem and social and economic development, and proposes a fractional differential equation to analyze and solve the contradictions between supply and demand, pollution, and overexploitation of agricultural water resources. The article also classifies the index system of the water resources carrying capacity evaluation model and simulates the balance of water supply and demand in the irrigation area.
