The development of ecological smart cities in the post-epidemic era

Abstract

With the accelerated development of globalization and urbanization, the advent of the post-epidemic era means that the world has begun to enter the recovery stage, and the rapid development of urbanization has caused cities to transform from a decentralized model to a centralized model. The growing population puts cities under tremendous pressure. This paper studies the case of Barcelona, analyzes and summarizes the development of Barcelona's ecological smart city, as well as the practical application of information technology and Internet of Things technology, and discusses the challenges faced by smart cities. The concept of ecological smart city consists of the Internet, openness, intelligence, innovation and green to form an urban planning framework. Lay out smart sensors according to the size and shape of urban space, and use smart technology to activate the city's ecosystem. The digitalization and IoT technology services of smart cities are not only conducive to the tracking and prevention of the epidemic, but also conducive to the recovery and development of the city in the post-epidemic era. Smart cities represent the development of a city that is more efficient, sustainable, and livable. The development trend of smart cities is characterized by the integration of advanced technologies to improve the quality of life of urban residents, improve sustainability, and optimize city operations.  Finally, it provides some suggestions and experiences for the development of smart cities in the world and expectations for the future of this field of research.
