Abstract

Taking the urban heat island (UHI) effect as the analysis object, studying the changes in temperature data and the frequency of extreme climates in Beijing in the past 30 years, the research shows that since 1980-2019, the ground temperature in Beijing has been increasing and has continued Deteriorating trend; winters have become shorter and summers have increased; after 2000, the total amount of precipitation in Beijing has decreased and the city has become more arid; however, the sandstorms in Beijing have improved significantly. Combining the statistical data of the current sampling survey on the application frequency of garden plants in Beijing and comparing the influence of plant coverage in central and suburban Beijing on urban temperature, the analysis shows that urban green space has a certain mitigation enact on the heat island effect. Studies have shown that a reasonable planting structure can improve the efficiency of plant cooling and increasing humidity. The collocation of trees, shrubs and herbs can weaken the negative impact of the UHI. In the selection of urban landscape plants, try to choose vegetation with large leaves, large canopy, complex structures, low canopy gap, high canopy density and high canopy layer, which can effectively slow down the UHI. It analyzes the lack of quantitative research and a large amount of data in the research on the effect of green space on urban heat island in China at this stage. The study proposes that Beijing should focus on governance and improvement in the urban heart where the UHI is serious, and put forward measures and suggestions for Beijing to alleviate the urban heat island effect in subsequent time.
