摘要:
文章采用逐年土地覆被数据（CLCD）对桂林市雁山区1996—2021年间的不透水面进行了变化分析，并根据两期Landsat卫星影像进行了地表温度反演，分析不同土地覆被类型与地表温度之间的关系。研究结果表明：25年间，桂林市雁山区不透水面占比不断增大，年均增长率为10.64%，其中1996—2001年、2006—2016年间，桂林市雁山区不透水面占比增速较快，其余年间增速较缓；通过分析不同土地利用类型与地表温度的关系，可以明显看出不透水面对应地表温度整体偏高，对城市热岛效应具有显著增强作用，而森林与水体对应地表温度整体偏低，对城市热岛效应具有显著缓解作用。因此，可以通过增设城市森林或水体景观来降低城市热岛效应，维护城市生态环境。
Abstract:
In this paper, the annual China Land Cover Dataset (CLCD) was used to analyze the changes of impervious surface in Yanshan District, Guilin City from 1996 to 2021.Based on two Landsat satellite images, surface temperature inversion is conducted to analyze the relationship between different land cover types and surface temperature. The results show that over the past 25 years, the proportion of impervious surface in Yanshan District of Guilin has been continuously increasing, with an average annual growth rate of 10.64%. Among them, from 1996 to 2001 and 2006 to 2016, the proportion of impervious surface in Yanshan District of Guilin increased rapidly, while the growth rate in other years was relatively slow. By analyzing the relationship between different land use types and land surface temperature, it can be clearly seen that the impervious surface responds to an overall high land surface temperature, which significantly enhances the urban heat island effect. However, forests and water bodies correspond to an overall low surface temperature, which significantly alleviates the urban heat island effect. Therefore, the urban heat island effect can be reduced and the urban ecological environment can be maintained by adding urban forest or water landscape, maintain the urban ecological environment.
