Method for quantifying cooling scale of urban large blue-green space based on landscape pattern

The invention discloses a method for quantifying the cooling scale of an urban large blue-green space based on a landscape pattern. The method comprises the following steps: S1, acquiring and processing an urban remote sensing image; s2, establishing an urban surface temperature inversion model; s3, acquiring urban surface land coverage information; s4, calculating the landscape pattern index of each scale of the city; s5, extracting a direct cooling range of the urban large blue-green space; and S6, establishing a multivariate stepwise regression model, and obtaining a potential cooling range of the large blue-green space based on the landscape pattern. The urban surface temperature inversion model is established based on the remote sensing technology, compared with human survey, the urban surface temperature can be quickly simulated, and human and material resources are saved; based on the urban landscape pattern and the multivariate stepwise regression model, the potential cooling effect of the urban large
