Outline
Under the background of rapid urbanization and industrialization, the risk of environmental damage to architectural heritage was increasingly exposed. Taking Tianjin as the research area, the advantages of macro and micro scale architectural heritage risk were comprehensively evaluated based on the environmental perspective of urban resilience. The construction heritage vulnerability environmental risk assessment system should be established with flood risk, comprehensive terrain and geological risk, atmospheric environment risk, fire risk, traffic facility risk and architectural heritage value risk as evaluation factors. Based on the past research, the quantitative factors were selected, and the spatial quantitative evaluation of geographic information system was used to screen 18 indicators and carry out correlation analysis. The research results show that the vulnerability areas of architectural heritage are highly concentrated in urban areas, and the influence of human factors is higher than that of natural factors. Generally speaking, the high vulnerability area is mainly concentrated in the peace area, which is distributed nuclear to the six districts in the city. Most of the architectural heritage is located in the six districts of the city, which has a high risk from the perspective of urban resilient environment.
