Abstract:

Various ecological problems caused by rapid urbanization have become the biggest obstacle to achieving high economic quality. Therefore, the construction of a coordinated development relationship between urban ecological resilience and urbanization is crucial for developing inland cities in arid regions. This study attempts to break through previous research methods and interpret the relationship between urbanization and ecological environment from the viewpoint of resilience. Based on nighttime light data and land use remote sensing data, the coupling coordination and relative development degree models were used to study their coupling coordination and spatio-temporal evolution in Ningxia, China, from 2005 to 2020. The results show that the urban agglomeration along the Yellow River in Ningxia, with Yinchuan City as the center, has bright lights, whereas the southern part of Ningxia presents many small scattered lights. The distribution pattern of ecological resilience is the highest in Wuzhong City, followed by Yinchuan City, and the lowest in Shizuishan City, Guyuan City, and Zhongwei City. Except for Yinchuan City and Shizuishan City, other cities have also experienced varying degrees of imbalance, and the relative development of urbanization and ecological resilience in Ningxia has not reached ideal equivalence. Finally, Ningxia gradually forms a coordinated regional development pattern, with Yinchuan City as the core and Shizuishan City and Wuzhong City as the support, radiating the cities of Zhongwei and Guyuan. This study makes up for the deficiency of research on arid cities. Resilience, as a new hotspot in the field of urban studies, provides a new way for interpreting the relationship between urbanization and ecological environment from the perspective of ecological resilience by constructing the evaluation index system of “resistance-adjustment-resilience”, which is greatly significant for accelerating the construction of an important ecological security barrier and realizing high-quality development in northwest China.

Key words: urbanization, ecological resilience, coupling coordination, Ningxia
