Under the background of urban heat island effect, using ENVI-met microclimate simulation quantitative analysis and regional microclimate survey as the research method, using wind efficiency index, temperature and humidity index and predicted average vote three indicators to comprehensively evaluate the human comfort level of the waterfront space microclimate in winter in the semi-arid regions of the North, exploring the complex influence of the embankment layout form and the distribution pattern of the vegetation on the microclimate of the city's waterfront, providing a reference value for the improvement of the environmental quality of the urban waterfront space. This will provide a reference for improving the environmental quality of urban waterfront space.
