| 研究実績の概要 |
This research program has been developing from April 2021 to March 2023. This program takes Tsukuba city and Tokyo central area as examples to assess the impact of landscape composition on urban heat islands by evaluating the distribution of three-dimensional building volume and the building functions on land surface temperature (LST). At the beginning of the study, we examined 110 academic articles to understand the links between land use/cover changes and urban heat islands based on multiple case studies. And the review results have been summarized as a review paper published in the Remote Sensing journal. Next, we collected and prepossessed remote sensing-derived land use/cover data and building information data. Furthermore, fieldwork was conducted to determine the actual urban structure and mechanism. We discovered a link between land use/cover distribution and LST. Different from previous studies, this research uses a single building rather than a traditional grid-based analysis; it is easy to discover the different properties of the building itself and provide the urban planners with a more detailed way to design the single building. Our results show that the management and control of building distribution, population density, and energy consumption could significantly reduce the LST effect, realize sustainable development, and create a healthy urban establishment in a planned city. The study's findings were presented at three academic conferences, and a portion of the findings have been submitted to an international publication.

| 今後の研究の推進方策 |
The plan for this year is to continue the spatiotemporal analysis of building distribution and land surface temperature. First, the part of this research (Urban heat island phenomenon in the edge of Tokyo metropolitan area: the case of Tsukuba city, Japan) will be presented at The 5th Asian Conference on Geography. Furthermore, the primary findings of this research are being prepared for presentation at Advancing Earth and Space Science Fall Meeting 2022 and a research paper for publication in Remote Sensing journal.
