濕地，被譽為“地球之腎”，在生物多樣性維護、氣候調節、固碳儲碳、水源涵養及提供生態服務等方面具有不可替代的作用，是生態文明建設和可持續發展的重要基石。隨著遙感技術的快速發展，濕地資源的動態監測與科學管理能力得到顯著提升，強化了濕地保護與修復。面對氣候變化的日益威脅，濕地的功能和脆弱性顯得尤為重要，其變化直接影響氣候系統的穩定性。聯合國《濕地公約》和國際社會持續強調濕地在減緩氣候變化中的關鍵作用，尤其是其固碳能力和緩解極端氣候事件的能力。然而，濕地的退化和喪失問題加劇，迫切需要利用遙感技術進行全球尺度的濕地動態監測和評估其對氣候的影響。

自2019年首屆中國濕地遙感大會在長春舉行以來，該大會已成為濕地科學與遙感領域具有國際影響力的學術盛會，推動了濕地監測、保護與管理實踐，並為我國濕地修復和氣候適應性管理提供了智力支援。2024年，國際數位地球學會中國國家委員會數字濕地專業委員會的成立標誌著中國濕地遙感研究進入新階段。為進一步深化濕地遙感與氣候變化領域的學術合作與技術創新，2025年11月28日至12月1日，第七屆全國濕地遙感大會將在香港大學舉行，主題為“濕地遙感與氣候變化”，由香港大學和廣州大學聯合承辦，旨在探討氣候變化下濕地生態系統的動態響應機制及其科學管理策略，共同為濕地保護與可持續發展貢獻智慧與力量。

Wetlands, often referred to as the "kidneys of the Earth," play an irreplaceable role in maintaining biodiversity, regulating climate, sequestering and storing carbon, conserving water resources, and providing various ecological services. They are a crucial cornerstone for the construction of ecological civilization and sustainable development. With the rapid advancement of remote sensing technology, the capabilities for dynamic monitoring and scientific management of wetland resources have been significantly enhanced, thereby strengthening wetland protection and restoration. In the face of the increasing threats posed by climate change, the functions and vulnerabilities of wetlands become particularly important, as changes in wetlands directly affect the stability of the climate system. The United Nations' Ramsar Convention on Wetlands and the international community have consistently emphasized the critical role of wetlands in mitigating climate change, especially their carbon sequestration capacity and ability to alleviate extreme climate events. However, the issues of wetland degradation and loss are worsening, necessitating the urgent use of remote sensing technology for global-scale dynamic monitoring of wetlands and assessing their impact on the climate.

Since the first China Wetlands Remote Sensing Conference was held in Changchun in 2019, the conference has become an internationally influential academic event in the fields of wetland science and remote sensing. It has promoted the practice of wetland monitoring, protection, and management, and provided intellectual support for wetland restoration and climate adaptation management in China. In 2024, the establishment of the Digital Wetlands Professional Committee of the International Society for Digital Earth China National Committee marked a new phase in China's wetland remote sensing research. To further deepen academic cooperation and technological innovation in the field of wetland remote sensing and climate change, the 7th National Wetlands Remote Sensing Conference will be held at the University of Hong Kong from November 28 to December 1, 2025. The conference, themed "Wetland Remote Sensing and Climate Change," will be jointly hosted by the University of Hong Kong and Guangzhou University. It aims to explore the dynamic response mechanisms of wetland ecosystems to climate change and their scientific management strategies, contributing wisdom and strength to wetland protection and sustainable development.
