RIASSUNTO
At present, rapid urbanization is bringing convenience and high efficiency to our daily lives, but the increase in GDP comes with the cost of high metabolic rates, high waste per capita, severe lack of resources, heavy pollution, and waste siege. This cost-expensive lifestyle leads to severe environmental degradation and soaring resource consumption. In this paper, we evaluate, from the UV perspective, the challenges of the environment system, including land pollution, water pollution and air pollution, and the current status of smart environmental protection systems based on the framework of closed feedback control loop: data acquisition, communication, decision-making and action. We propose that effective smart environmental protection should take into consideration the interaction between environmental protection subsystems and other seven smart city subsystems: smart home, smart medicine and healthcare, intelligent transportation, urban planning and crowd management, smart energy management, smart city infrastructure, smart response system for city emergency, and smart humanity, and also study how smart environmental protection would be affected by four major impacting factors of smart cities: information flow, material cycle, lifestyle and community. This systematic study will help us explore in depth the complicated dynamic relationship between multiple impacting factors and propose a UV-oriented, integrated, resilient, inclusive and sustainable development framework design to address current imminent challenges and to improve our living environment through real-time monitoring of pollution, crowd-sourcing based on hazard reports, identification of pollution sources, preventive waste and pollution control based on comprehensive management of material cycles and personalized lifestyle guidance and suggestions.
