Study on the coupling model of urbanization and water environment with basin as a unit: A study on the Hanjiang Basin in China

The urbanization process of the Hanjiang Basin is speeding up and facing many challenges. It is necessary to take active actions to realize the balance between urbanization development and water environment protection. This paper aims to establish a comprehensive evaluation model of urbanization and...
