厦门市城市规模与城市热环境的关联研究

Study on the Correlation Between City Size and Urban Thermal Environment in Xiamen

城市的迅速扩张导致城市地表覆被属性发生变化,进而引发城市热岛效应等城市气候环境问题。深入探索城市规模对研究城市热环境的驱动机理,缓解城市热岛效应,实现城市健康发展具有重要意义。本研究基于厦门市的Landsat遥感影像数据,应用统计分析方法,定量探讨了城镇建成区斑块面积与相对地表温度的耦合关系。并根据研究结论,为厦门市城镇建成区分区优化提出了规划建议。研究结果可为改善城市生态环境、缓解城市热岛效应提供理论参考。

With the rapid expansion of urban areas,the land cover of urban areas has changed,leading to increasing prominent urban heat island effect and other urban climate and environmental problems.Exploring the effects of city size on thermal environment is of great significance to alleviating urban heat island effect and realizing the healthy development of the city.Based on Landsat remote sensing image in Xiamen,statistical analysis method is used to analyze the coupling relationship between urban built-up patch area and relative land surface temperature.According to the research conclusions,some planning suggestions are put forward for partition optimization of urban built-up areas in Xiamen.The research results can provide theoretical reference for improving the urban ecological environment and alleviating the urban heat island effect.
