秦大河:面向可持续发展的冰冻圈科学

 

 21世纪以来, 在全球气候变暖的大背景下, 冰冻圈科学发展快速。在梳理国际冰冻圈相关研究态势、 分析中国相关研究动向的基础上, 总结了冰冻圈科学发展的历程并简要介绍了冰冻圈科学的基本框架。研究指出, 20世纪70年代冰冻圈概念正式提出以来, 国际社会以推出气候与冰冻圈(WCRP-CliC)计划和成立国际冰冻圈科学协会(IACS)为标志, 并在深化冰冻圈自身机理、 过程认识的同时, 更加关注与其他圈层之间相互作用中的冰冻圈效应, 表明冰冻圈研究趋向变化 - 影响 - 适应这一主线发展, 在一定程度显现出了冰冻圈科学的核心特征。中国冰冻圈研究近20年、 尤其是近10年发展迅猛, 沿着冰冻圈科学的主体思路, 在冰冻圈变化, 冰冻圈变化对生态、 水文、 气候、 地表环境以及社会经济的影响等方面取得了系统性成果, 对冰冻圈科学的内涵和外延有了系统的认识。在分析国际冰冻圈科学孕育和发展背景和简要总结中国冰冻圈研究近况基础上, 对冰冻圈科学学科框架体系从科学内涵和外延、 研究构架和学科组成等方面进行了论述, 冰冻圈科学已经成为一门涉及广泛、 过程机理研究与可持续发展密切关联的全新学科。

Abstract

The Cryospheric Science has developed rapidly since 21st century under the background of global warming. This paper summarizes the development process and briefly introduces the basic framework of Cryospheric Science on the basis of reviewing the international and Chinese relevant researches on cryosphere. Since the concept of cryosphere was officially proposed in the 1970s, the international community has taken more attention on the impacts of cryosphere in the interactions between other spheres while deepening the understanding of the mechanisms and process of the cryosphere, which can be marked with the launch of the Climate and Cryosphere (WCRP-CliC) plan and the establishment of the International Association of Cryospheric Sciences (IACS). It indicates that the study of the cryosphere tends to along the mainline of change - impact - adaption, and has illustrated the core characteristics of Cryospheric Science in a certain extent. The study on Chinese cryosphere has been developing rapidly following the mainline of Cryospheric Science in the past 20 years, especially in the past 10 years. It has presented systematic achievements in terms of changes in the cryosphere and the impacts of changes in the cryosphere on ecology, hydrology, climate, surface environment, society and economy, and also get systematic understanding of the connotation and extension of the Cryospheric Science. Based on short introduction on the background of the gestation and development of the Cryospheric Science and a brief summary of the current status of cryospheric research in China, the paper discusses the disciplinary framework of Cryospheric Science from the scientific connotation and extension, research methods, to discipline constitutes. It suggested that Cryospheric Science has become a new discipline involving a wide range from process and mechanisms to impacts and adaptation, which closely related to sustainable development.
