理大研究揭示「藍綠灰」基建緩解城市熱島成效

土地及空間研究院管理委員會成員兼土木及環境工程學系教授郭海教授及其全球多名合作者的一項創新研究，揭示了「藍綠灰」基建（GBGI）在全球不同地區的降溫成效。研究成果已於跨學科國際期刊《The Innovation》發表。   研究發現，GBGI對降低城市熱量的效果因地區和城市而異。在歐洲、亞洲、北美洲及澳洲地區，GBGI的整體降溫效果分別最多達18.9°C、17.7°C、12°C及9.63°C。以全球來說，綠色和藍色基建對降溫非常有效，前者通過蒸發、蒸騰、遮陽和隔熱等作用來調節城市熱量，後者則通過水份蒸發吸收熱能，從而達致為周邊區域降溫的效果。   是次研究更揭示了多項GBGI基建對緩解中國內地不同地區和城市熱島效應的效果，其中效果最為顯著的設施包括園林、濕地、綠化牆和滯留池，可分別降溫達10°C、9.27°C、8°C和7°C。雖然華北及華南地區的GBGI整體降溫效果相近，但部分設施在同一區域不同城市的降溫效果有明顯差異。在北京，園林有助降溫10°C，但在陝西，卻只有2.7°C。在香港，公園、綠化天台和高爾夫球場，可分別降溫4.9°C、4.9°C和4.2°C，這對紓緩城市過熱問題尤為重要。   新聞稿：https://polyu.hk/IQuoi 閱讀全文：https://www.sciencedirect.com/science/article/pii/S2666675824000262?via%3Dihub 網上報導: 星島日報 - https://polyu.me/4bbXhvP 星島頭條 - https://polyu.me/4bYufjt 大公報 - https://polyu.me/3K1bUGq 點新聞 - https://polyu.me/3UIActC 新華社財金社 - https://polyu.me/3K719Cg 香港中通社 - https://polyu.me/44HGhex 美聯社 - https://polyu.me/3UHAC3v 經濟通 - https://polyu.me/3V3LgTw 澳門商訊 - https://polyu.me/3UJ5CA7 台灣產經新聞網 - https://polyu.me/3V1UkZ5 環球網 - https://polyu.me/4bIX8zF 大灣區商業科技專刊 - https://polyu.me/3V6Aj3O 華夏財經 - https://polyu.me/4biIXSo 中國科技網 - https://polyu.me/44J3mxq 科學雜誌- https://polyu.me/4bQn7p4 科學日報- https://polyu.me/4avRaRS  

土地及空間研究院代表團赴上海及天津考察

2024年5月11日至13日，土地與空間研究院管理委員會成員殷建華教授，聯同香港工程學會岩土分部卓成發主席，率團到上海及天津進行技術考察。為期三天的活動旨在透過了解當地疏浚土吹填成陸工程項目案例，從而促進探討及開發有利香港可持續填海和土地發展的潛在技術。   團隊先後到訪上海洋山深水港、疏浚技術裝備國家工程技術中心試驗基地，以及天津南港工業區和東疆港區。是次考察由理大與香港工程師學會岩土分部聯合主辦，以及由疏浚技術裝備國家工程研究中心和中交海洋建設開發有限公司承辦。

理大研究城市工業用地擴展對經濟和碳排放的影響

土地及空間研究院副院長兼地理信息學和人工智能講座教授翁齊浩教授及其團隊，近日於《通信地球與環境》期刊發表了題為「城市工業用地擴展對經濟增長和二氧化碳排放的不均等影響」的研究。   團隊利用衛星數據和機器學習，針對10個高工業附加值的國家繪製了具有30米解析度的工業用地地圖，並分析了2000年至2019年間工業用地擴展對216個地區的經濟成長和排放的影響。研究顯示，工業用地擴展是發展中地區經濟增長和排放的主要因素，貢獻率分別為31%和55%。相反，對已發展地區而言，工業用地擴展對經濟增長和排放的影響相對較小（分別為8%和3%），而經濟成長動力則轉向教育等其他因素。研究結果鼓勵發展中地區在擴展工業用地同時考慮對氣候變化所造成的負面影響，並鼓勵已發展地區在進行發展過程中，優先考慮投資於建設人力資本，而非進一步擴展土地。   閱讀全文：https://doi.org/10.1038/s43247-024-01375-x

土地及空間研究院院長對中國大城市快速下沉的研究給予專業意見 (只有英文版本)

Prof. DING Xiaoli, Director of the RILS and Chair Professor of Geomatics of LSGI, was interviewed by the journal Nature and BBC World Service’s programme “Newshour” to comment on a paper which suggests that some 16% of the mapped area of China’s major cities is sinking rapidly, and one in ten residents of China’s coastal cities could be living below sea level within a century. Prof. DING pointed out that while subsidence is not only a problem in China, the study, which was led by a scholar from Peking University, provides an interesting snapshot of the situation in China, and crucially links the issue to the populations affected. According to Prof. DING, the use of groundwater is the main cause of subsidence, and controlling the use of groundwater would be the key for controlling the problem.   Online coverage: Nature - https://polyu.me/4b2VFE5 BBC World Service - https://polyu.me/3xKqaQY (45:05 - 49:05) (registration required) Jandan - https://polyu.me/3U8hueF

理大研究發現沿海地區出現「熱浪與極端海平面併發」現象顯著增加

土地及空間研究院、可持續城市發展研究院及潘樂陶慈善基金智慧城市研究院成員兼土地測量及地理資訊學系副教授王碩博士及其研究團隊發現，1998年至2017年間，在同一沿海地區同時出現熱浪和短期極端海平面上升的情況，較20年前顯著增加。研究亦表明，在高排放場景模型中，2025年至2049年間發生此類事件的概率可能會增加五倍。該研究結果提供了科學證據及指南，旨在改進應對極端天氣事件的氣候適應策略，這將助於促進氣候韌性沿海城市的發展。此項研究已發表於期刊《Communications Earth & Environment》。 閱讀全文：https://www.nature.com/articles/s43247-024-01274-1   網上報導： 聯合國減災戰略署-https://www.preventionweb.net/news/study-identifies-increased-threat-coastlines-concurrent-heat-waves-and-sea-level-rises 科學美國人- https://www.scientificamerican.com/article/heat-and-floods-are-increasingly-hitting-coastlines-with-a-one-two-punch/ 自然亞洲-https://www.natureasia.com/ja-jp/research/highlight/14874 中央電視台 - https://polyu.me/3JhABOe 新華網 - https://polyu.me/3JjRsjK 人民日報 - https://polyu.me/49CbO2i People.com - https://polyu.me/4cQaED4 江南晚報 - https://polyu.me/3QrfEET 金華日報 - https://polyu.me/4aQ7iyN 論文 - https://polyu.me/4aVfflH 網易 - https://polyu.me/3VWKNDu 福布斯 - https://polyu.me/4aw2tKM 海峽時報 - https://polyu.me/3W0TgWf 法國 24 - https://polyu.me/43VGjiq 南非目擊者新聞 - https://polyu.me/3VSO2vK 印度德干先驅報 - https://polyu.me/3vGHlCp 印度加爾各答電訊報 - https://polyu.me/49Afgdy 馬來郵報 - https://polyu.me/3vHSjaO Daily Excelsior - https://polyu.me/4aWw145 EurekAlert - https://polyu.me/3UgcSV1 中新社 - https://polyu.me/3W2qmoV 鳳凰新聞 - https://polyu.me/3UdjgMT

理大研究發現綠化及冷屋頂可大幅節能

土地及空間研究院副院長兼地理信息學和人工智能講座教授翁齊浩教授及其團隊，研究綠化及冷屋頂在降低建築能源消耗方面的節能潛力。研究已發表於《npj Urban Sustainability》期刊。   該研究審視了開羅、香港、首爾、倫敦、洛杉磯和聖保羅等六個全球城市在當前和未來氣候變化狀況下的綠色及冷屋頂策略。結果顯示，在未來的氣候條件下，在城市層面實施這些策略可每年節省高達 65.51%能源消耗，以及減少71.72%的供暖、通風及空調能源消耗。此項研究提供了有用參考，有助指引全球不同氣候區實施相關策略，按城市環境狀況而選擇和設計適切的屋頂方案。   閱讀全文：https://www.nature.com/articles/s42949-024-00159-8（只有英文）

土地及空間研究院副院長榮獲著名的 2024 年 AAG Wilbanks 地理轉型研究獎和 2024 年 RSSG 終身成就榮譽獎 (只有英文版本)

The Associate Director of RILS, Prof. Qihao WENG, has been honoured with the 2024 AAG Wilbanks Prize for Transformational Research in Geography on 6 March 2024. This prestigious award is presented by the American Association of Geographers (AAG), an organisation that brings together more than ten thousand members of the global geographic community. The Wilbanks Prize is awarded to geographers who have made groundbreaking contributions in the fields of Geography or GIScience, or to Science and Society more broadly.   Equally important, Remote Sensing Specialty Group (RSSG) of AAG, which is dedicated to promoting the understanding of remote sensing science, fosters dialogue and interaction among geographers in the application of remote sensing technology in various domains, including research, teaching, public service, and private enterprise, also announces Prof. WENG as the esteemed recipient of the RSSG’s Lifetime Achievement Honor Award for the year 2024, which is a testament to Prof. WENG's unparalleled contributions to the discipline of remote sensing, marked by a distinguished career encompassing ground-breaking research, dedicated education, and impactful service engagement.   Prof. Qihao WENG, a Foreign Member of The Academy of Europe (Academia Europaea), and a Fellow of IEEE, AAAS, ASPRS and AAIA, is currently a Chair Professor at the The Hong Kong Polytechnic University (PolyU), Associate Director of RILS, and a Global STEM Scholar. Prof. WENG worked as Director of the Center for Urban and Environmental Change and a Professor of Geography at Indiana State University, 2001-2021, and was a Senior Fellow at the National Aeronautics and Space Administration from 2008 to 2009. Additionally, Professor Weng is the Lead of GEO Global Urban Observation and Information Initiative, 2012-2022, and is an Editor-in-Chief of the ISPRS Journal of Photogrammetry and Remote Sensing.   Prof. WENG has defined urban remote sensing as a new field and has transformed urban environmental research with theoretical and technical advances, including novel algorithms and innovative methods for sub-pixel-scale analysis and time series imagery. His research has significantly advanced our theoretical understanding and empirical knowledge of urban heat islands, urban sprawl, urbanization effects, and urban environmental sustainability. By establishing relationships among satellite thermal infrared imagery, land surface temperature, and air temperature, his research connects remotely sensed data to urban spatial patterns, radiation budgets, and climate change. His 2004 methodology for estimating land-surface temperature from satellite-derived attributes of vegetation, developed with Lu and Schubring, has had far-reaching impacts in a range of fields, including urban geography, landscape ecology, urban planning, urban meteorology, and climatology.   The AAG will celebrate the 2024 Awards and Honors at an awards celebration during the 2024 AAG Annual Meeting in Honolulu, Hawaii, in April 2024.
