Urban environmental effect refers to the comprehensive effects of the positive and negative impacts of various urban activities on the natural environment, including the impacts of pollution, biology, earth, resources and landscape. Exerting favorable influence on the environment will produce positive effects on the environmental system; otherwise negative effects. When the environmental system has a stable and orderly structure, its ability to bear the harmful influence from the outside is stronger, and the response time to the negative effect will be longer. When the environmental system is fragile, the ability to resist harmful effects is low, and the response time of the system is short, which easily leads to the decline of the environmental system.
