Abstract
In China, with the acceleration of urbanization, people pay more attention to the quality of urban environment. Air pollution, vegetation destruction, water waste and pollution, and waste sorting have restricted the sustainable development of urban environment. It is important to evaluate the impact of these environmental concerns as a prerequisite to implement an effective urban environmental sustainability policy. The aim of this paper is to establish a system for evaluating sustainable urban environmental quality in China. We extracted six dimensions and 29 criteria for assessing urban sustainable environment. Then, a fuzzy technique and the best worst method were applied to obtain the weights for the dimensions and criteria. Next, grey possibility values were applied to evaluate the sustainable environmental quality of five cities: Beijing, Shanghai, Shenzhen, Guangzhou, and Hangzhou in China. A sensitivity analysis was performed to identify how the ranking of these five cities changed when varying the weights of each criterion. The results show that pollution control, the natural environment, and water management are the three most important dimensions for urban environmental quality evaluation. We suggest that controlling pollutant emissions, strengthening food waste management, improving clean production processes, and utilizing heat energy are the effective measures to improve the urban environment and achieve sustainable urban environmental development.
Highlights
Under the background of economic growth and urbanization process in China, the urban environment has been disrupted, and the sustainable development of urban environment has been threatened [1]
For the importance of dimensions (Table 7), the results indicated that pollution control (D6, 0.293), natural environment (D1, 0.192), and water management (D4, 0.178) were the three most influential dimensions for urban sustainable environmental quality
This study proposed six dimensions and 27 criteria to evaluate urban environmental quality
Summary
Under the background of economic growth and urbanization process in China, the urban environment has been disrupted, and the sustainable development of urban environment has been threatened [1]. The urban heat island effect and the health problem of urban residents are the challenges for facing the sustainable development of cities [2]. China has increased too rapidly and they are increasingly devoting their attention to ecological environment construction. Rapid urbanization and modernization have increased the pressure of urban environmental development in China. As the largest developing country in the world, China has made a rapid urbanization and modernization. China’s urbanization rate has increased from less than 20%
