Abstract: The concept of vulnerability was introduced into the study of regional atmospheric environment, on the basis of the framework of research on the vulnerability of exposuresensitivityadaptability,using combination method of geographic information system (GIS), multicriteria decision analysis (MCDA) and ordered weighted averaging (OWA) method, considering the human activities, atmospheric environment and socioeconomic factors. We constructed avulnerability assessment model of atmospheric environment based on the influence of human activities. We took BeijingTianjinHebei region as an example to explore the practicability of the model, and verified the relationship between human activities and vulnerability of urban atmospheric environment.

Key words: multicriteria decision analysis, atmospheric environment, human activity, vulnerability assessment, ordered weighted averaging model
