摘要

With the acceleration of urbanization, urban climate and environmental problems such as urban heat island effect has become more and more prominent. Taking Zhengzhou City as an example, this paper uses meteorological analysis, remote sensing technology and geographic information system technology to determine the functional space and compensation space of urban ventilation corridors, and analyzes the potential correlations among various influencing factors. The results showed that: (1) There was an obvious heat island effect in the urban area of Zhengzhou City, in which the increase of artificial surface contributes particularly to the increase of Land Surface Temperature (LST). (2) In Zhengzhou, the wind environment was mainly southeasterly in summer and southwesterly in winter. The ventilation potential value in the eastern was better than that in the west, and the frequency of the dominant wind direction at the urban center was lower than at peripheral stations. (3) Combined with the factors of LST, topography, road length, building density, water length, sky view factor and NDVI in Zhengzhou, 3 potential ventilation corridors framework was determined. The research results could provide theoretical supported for the study of urban wind-thermal environment and provided reference schemes for urban planners to alleviate urban thermal environment problems.
