Tóm tắt

 This study found out the patterns of urban heat islands in Hanoi: the heat islands are concentrated as large zones in the high construction density urbans, which are also developed of economy and urbanization
  Line forms in suburban areas with medium construction density - where planning is in progress and scatters in the low construction density areas - the slower economic development and urbanization. Duration of 12 years, the total urban heat island area in Hanoi has tripled (from 3.1 % to 9.4 %) and the difference of land surface temperature between the lowest value and highest value also increased significantly from 16.9 °C (2009) to 18.7 °C (2021). The increase of urban heat islands is corresponding with the progress of Hanoi urban planning implementation. The results probably contribute to the decision-making of sustainable urban planning and development in the contemporary context of climate change and rapid urbanization.
