尊敬的北京林业大学副校长李雄教授,尊贵的嘉宾,亲爱的朋友和同事们,女士们,先生们,
早上好!
作为联合主席,我代表国际草地生态学会议组织委员会和学术委员会向大家致以最诚挚的问候。热烈欢迎您参加由北京林业大学主办、北京林业大学草地学院和内蒙古科尔沁草原生态国家野外科学观测研究站承办、中国草地学会草地管理委员会、中国草地学会草地生态委员会、生态学会长期生态研究委员会、中国生态文明研究与创新战略联盟、《草地与牧草科学》杂志、南京农业大学农草学院协办的国际草地生态学会议:气候变化与适应。
在这美丽的金秋季节,我们齐聚北京,讨论全球关注的生态学问题:草地生态系统中的气候变化与适应。众所周知,草地是世界上最重要的生物群落和生态系统之一。覆盖全球约40%的领土和近70%的全球农业用地,草地不仅是重要的植物、动物、微生物等物种的全球生物多样性储存库,还为我们人类提供广泛的物质和非物质利益,包括众多生态系统服务,如粮食生产、水资源供应和调控、碳储存和气候缓解、植物授粉以及一系列文化服务。尽管草地的重要性非凡,但全球范围内包括欧亚大草原、北美大草原、南美大草原、东非和澳大利亚稀树草原、南非大草原以及全球范围内其他类型的草原正受到持续的全球变化尤其是气候变化的威胁。作为主要驱动因素,全球变化显著影响了草地生态系统的功能和过程,导致世界许多地区草地普遍退化,目前世界范围内近一半的草地已退化。除了文化价值之外,草地退化可能给数以亿计靠草地获取食物、燃料、纤维和药用品的人们带来巨大风险。此外,草地退化可能带来巨大的环境问题,如水土流失、生物多样性丧失和温室气体排放。
这些严峻的问题使全球各地的专业人士和从业者思考全球草地的未来可持续性。正如我们所知,世界卫生组织提倡“同一健康”的概念,即关注地球上人类、生物和生态系统的整体健康。今天,我想提出一个概念“同一草地”,以突出在全球变化时代促进全球草地可持续性的重要性。学术界、政策制定者和从业者应认识到全球各地主要利益相关者之间有效合作的必要性,以更好地理解不同生物组织尺度的影响。协调和协作的网络研究是探索区域和全球尺度上全球变化影响的强大工具。养分网络、干旱网和NPKD极大地增进了我们对全球范围内富营养化、干旱以及二者相互作用对草地生态系统的影响的理解。为进一步促进更多研究网络之间的合作并为全球草地科学家建立桥梁,我们组织此次会议,审视气候变化对全球草地的影响以及适应这些影响的策略。
基于与会专家和无法参加本次会议的众多专家们对全球草地研究的广泛经验,我们确定了六个重要的会议主题领域:(1)气候变化对草地生态系统服务和功能的影响;(2)营养添加与健康草地生态系统的营养管理;(3)保护草地生物多样性以应对气候变化;(4)草地生态系统中的碳循环和气候变化;(5)植物-土壤界面和草地生态系统的稳定性对气候变化的响应;(6)气候变化时代的草地生态系统适应管理。这些主题领域构成了本次会议的基础。此外,这些重要问题将吸引更多国内外个人和组织,共同从草地的角度审视气候变化和适应,并为建立有效合作伙伴关系搭建平台。热烈欢迎您加入,以期达成多机构合作来共同应对这些关键问题。
本次会议邀请了多位来自国内外草地生态学和全球变化领域的知名专家和学者,以及来自世界各地的200多名参与者。预祝本次会议取得圆满成功,并成为长期合作的开端。我衷心祝愿所有与会者在北京能有所收获并度过一段愉快的时光。Chairman’s Speech at International Grassland Ecology Conference: Climate Change and Adaptation
Distinguished Vice President of Beijing Forestry University, Prof. Li Xiong, Esteemed guests, dear friends and colleagues, ladies and gentlemen,As a co-chair, I would like to express my best regards to all of you on behalf of the organization and academic committees of International Grassland Ecology Conference: Climate Change and Adaptation. You are warmly welcomed to this important conference organized by Beijing Forestry University, sponsored by School of Grassland Science, Beijing Forestry University and National Ecological Research Station of Inner Mongolia Horqin Grassland Ecosystem, co-sponsored by Grassland Management Committee of Chinese Grassland Society, Grassland Ecology Committee of Chinese Grassland Society, Long-Term Ecological Research Committee, Ecological Society of China, The National Innovation Alliance for Grassland Conservation in the Agro-Pastoral Ecotone, Journal of Grass and Forage Science, College of Agro-grassland Science, Nanjing Agricultural University.In this beautiful golden season, we are gathering in Beijing to talk about the hot issue: Climate Change and Adaptation in Grassland Ecosystem. As many of you know, Grassland is the one of most important biomes and ecosystems in the world. Covering around 40% of the global territory sand nearly 70% of the agricultural land area in the world, grassland not only serves as an important global reservoir of biological diversity including plants, animals and microbes, but also provides a wide range of material and non-material benefits to our human beings, including numerous ecosystem services, such as food production, water supply and regulation, carbon storage and climate mitigation, pollination and a host of cultural services. Despite the extraordinary importance of grassland, the sustainability of the different grasslands worldwide including Steppe in Eurasia, Prairie in North America, Pampas in South America, Sanvanna in Eastern Africa and Australia, Veld in South Africa and many more other types of global grasslands, is being threatened by the ongoing global changes, particularly climate change. As key drivers, global changes have significantly impacted the functions and processes of grassland ecosystems, resulting in widespread degradation in many parts of the world, with nearly half of total grassland area in the world degraded at present. Grassland degradation may cause enormous risks to the hundreds of millions of people who live on grasslands for food, fuel, fibre and medicinal products, in addition to cultural values. Furthermore, grassland degradation may create tremendous environmental problems, such as water and soil erosion, biodiversity loss, and greenhouse gas emission.This critical situation is challenging professionals and practitioners worldwide to think about the future sustainability of the grasslands worldwide. As we know, the World Health Organization (WHO) is advocating the concept of “One Health”, which is addressing the overall health of human beings, living creatures and ecosystems on the earth planet. Today, I world like to propose a term “One Grassland” to highlight the importance of promoting the sustainability of grasslands worldwide in the era of global changes. The academia, policymakers and practitioners should acknowledge the necessities of effective collaborations among key stakeholders across the worlds, as well as a better understanding of the influence of differing scales of biological organization. Coordinated and collaborative network research serve as powerful tool for exploring the effects of global change at both regional and global scales. Nutrient Network, Drought Net, and NPKD have greatly enhanced our understanding of the effects of eutrophication, drought, and their interactions on the grassland ecosystems across the world. To further promote collaboration among many more research networks and establish a bridge for worldwide grassland scientists, we organize this conference to examine the impacts of climate change on the global grasslands and adaptation strategies to cope with these impacts.Based on extensive experiences obtained from the grassland studies worldwide by the experts in this room and many more who can not attend this conference, we have identified six major thematic areas for the conferences: (1) Impacts of climate change on grassland ecosystem services and functions; (2) Nutritive addition and nutrition management for healthy grassland ecosystems; (3) Grassland biodiversity conservation in coping with climate change; (4) Carbon cycling and climate change in grassland ecosystems; (5) Plant-soil interface and stability of grassland ecosystems in response to climate change; (6) Adaptive management of grassland ecosystems in era of climate change. These thematic areas form the basis for this conference. In addition, the importance of these areas is expected to attract research interest from many more individuals and organizations inside and outside China to jointly examine Climate Change and Adaptation from the perspective of grassland and to serve as platform models for building effective, collaborative partnerships. All of you are warmly welcome to join the research networks hand in hand, as multi-institutional collaboration is central to successfully addressing these key issues.This conference has invited a group of well-known experts and scholars from both domestic and international communities in grassland ecology and global change. In addition, this conference has attracted more than 200 participants from different corners of world. I hope this conference will be a big success and the beginning of many long-term collaborations. I sincerely wish all the participants a productive and pleasant stay here in Beijing.
