摘　　要：自2005年联合国《千年生态系统评估》发布以来,旱区农业生态系统评估与管理研究越来越受到世界各国的广泛关注和重视。综述了2010年7月19日至25日在兰州大学举行的第二届生态系统评估与管理(Ecosystem assessment and management,EAM)国际会议28场特邀专家报告,围绕"气候变化与旱区农业生态系统管理"主题,分别从生态系统时空格局、全球变化生态学、植物逆境适应机制、植物与土壤关系和生态系统管理五个方面进行总结,旨在探讨全球气候变化条件下如何提高干旱与半干旱脆弱农业生态系统生产力和可持续性发展的创新理论研究。对生态系统评估与管理的未来发展趋势和目标进行了探讨,并对该会议将来的举办和组织形式提出了建议。In recent years,sustainable management of ecologically fragile regions has received increasing attention globally.The eco-system quality evaluation and integrative management are widely recognized as important foundation to achieve sustainable development in degraded semiarid and arid regions.At present,China′s western arid and semi-arid regions are faced with a series of ecological degradations such as soil erosion,water shortage,and land degradation at a time of global warming.Under the sponsorship of ＂111＂ Program,the 2nd International Workshop on Ecosystem Assessment and Management（EAM） was held in Lanzhou from July 20 to 25,2010,jointly hosted by Lanzhou University（LZU） and the University of Western Australia,（UWA） funded by the State Administration of Foreign Experts Affairs and the Ministry of Education of China.In addition,Acta Ecologica Sinica,Agricultural Ecological Professional Committee of Ecological Society of China,and the Gansu Administration of Foreign Expert Affairs also strongly supported the Workshop.The Workshop focused on agricultural development in arid and semi-arid areas and the status quo of the ecological environment and social development of the region.The theme of the Workshop was ＂Climate change and dryland agricultural ecosystem management＂.The objective was to develop a methodology of assessment and management of semi-arid rainfed agro-ecosystem and oasis agro-ecosystem in arid areas.There were five topics in the workshop： the tempo-spatial patterns of ecosystem,global change ecology,the adaptive mechanism of plants under adverse stresses,plant and soil relations and the strategic management of ecosystem.Twenty-eight experts from abroad and home were invited to the workshop to present current developments on global climate changes and ecosystem management,with emphasis on how to improve the productivity and sustainable development of the arid and semi-arid agro-ecosystems under climate change.The workshop was attended by more than 200 participants.Future deve
