项目摘要

Big amounts of anthropogenic heat are released through air conditioners, plants, vehicles, and other heat sources in urban areas due to the high human density and density of buildings, as well as the heat that is retained and radiated by these big, intricate structures. The objective of this study is to evaluate the influences of building composition on land surface temperature (LST) in the Tsukuba city and Tokyo central area, as well as to investigate any potential anthropogenic elements that may be causing these influences. Previous studies usually took the grid as a unit to analyze the LST distribution. This study focuses on each building and its surrounding condition (45m buffer) to investigate the building LST and its relationship with other anthropogenic variables. Similar to previous findings, our study found that the LST was mainly focused on the building distribution and population density. And it was observed that the LST decreased following the increasing of vegetation cover in Tsukuba central area. This result is, in contrast to a previous study, that the LST is not increased with building volume. This is the result of the urban planning in which the building and green space are interspersed with each other in Tsukuba city. The results of the research were presented at the 5th Asian Conference on Geography on September 5th, 2022 and the 2nd Workshop of Asian Young Geographers on November 30th,2022. The above research results have been presented at two international conferences and accepted in five international and domestic academic journals.

由于城市地区人口密度和建筑物密度高，以及这些大型复杂结构保留和辐射的热量，大量的人为热量通过城市地区的空调、工厂、车辆和其他热源释放。本研究的目的是评估筑波市和东京中心地区的建筑结构对地表温度 (LST) 的影响，并调查可能造成这些影响的任何潜在人为因素。以往的研究通常以网格为单位来分析LST分布。本研究重点关注每栋建筑及其周围条件（45m缓冲区），以研究建筑LST及其与其他人为变量的关系。与之前的研究结果类似，我们的研究发现LST主要集中在建筑物分布和人口密度上。据观察，筑波中心地区的地表温度随植被覆盖度的增加而下降。与之前的研究相比，这一结果表明地表温度不会随着建筑体积的增加而增加。这是筑波市建筑与绿地相互穿插的城市规划的结果。该研究成果于2022年9月5日召开的第五届亚洲地理学会议和2022年11月30日召开的第二届亚洲青年地理学家研讨会上发表。上述研究成果已在两次国际会议上发表，并被五种国际国内学术期刊接收。
