Land cover change evaluation based on eco-economic balance modeling

Abstract

Water supply is one of the important functions provided to humans by the ecosystem. Water supply by the ecosystem leads to sustainable economic development, ecological restoration and food security for human societies. Therefore, the evaluation of the water supply capacity of the ecosystem and the analysis of its spatial distribution features play an important role in the implementation of the plan for the protection and exploitation of water resources. Evaluation of ecological economic balance is of great importance in sustainable ecosystem management. This paper was conducted to develop the ecological economic balance structure based on the water supply and land cover changes. Land use was considered in four time periods from 2000 to 2021 with seven-year intervals to evaluate the process of land cover change and water availability. The results showed that the southern and eastern regions addressed a negative trend in the ecological economic balance. These areas have been affected by population growth and urbanization. HIGHLIGHTS Water supply plays an important role in assessing ecological economic.; Water supply have caused obvious changes in land use/cover and have increasedthe need for soil protection.; Rainfall, evapotranspiration and land use should be considered in eco-hydrological planning.;
