Calculation and analysis of sight corridor space of urban multiarchitectural heritage

Chinese culture has a long history, and there is a lot of architectural heritage in many cities. However, with the development of the economy, the height of urban buildings continues to break through the upper limit of height, and the density of buildings increases, which inevitably blocks the architectural heritage. Therefore, the sight corridor model is adopted to construct multi-type sight corridors according to the characteristics of architectural heritage and the occlusion area of the study, and the height of the surrounding buildings of the architectural heritage is controlled. Taking Kaifeng as an example, the occlusion of urban buildings is reduced.
