摘　　要：干旱区是受气候变化影响最大的地区,旱区生态系统可持续性与粮食安全是最为关注的热点问题。2013年3月国际旱区发展委员会(IDDC)和中国科学院等十家单位在北京举办了第十一届国际旱区发展大会,会议围绕"气候变化下干旱区的粮食及能源安全"主题共做了114场报告,其中旱区生态系统可持续管理是最突出的主题。本文综述了大会主要报告内容,包括气候变化对旱区生态系统的影响、旱区水土资源利用、农业生态系统管理、草地发展与牧草管理、植物逆境生理学、旱区植物抗性改良新技术应用和旱区社会-自然和生态耦合关系等诸多方面。最后还对会议主题进行了述评,就旱区态系统可持续管理与社会经济和居民生计等耦合关系进行了讨论。The dryland areas are most affected by the impact of climate change. Ecosystem sustainability and food security in dryland areas are two hot issues of the international concern. The Eleventh International Dryland Devel- opment Conference was jointly organized at Beijing in March, 2013 by ten units such as the international land devel- opment committee （IDDC） , the Chinese Academy of Sciences and so on. The main theme of this conference was food and energy security in dryland areas under climate changes and there are 114 presentations in all, in which the sustainable management of ecosystems in dryland areas is the most prominent. This paper summarized the main con- tents of the conference, that cover many aspects in dryland area under climate changes like global climate change and its impact on different dryland ecosystems, sustainable use of water resources in dry areas, sustainable land use and management in dry areas, sustainable range management under global climate change, stress physiology： drought, heat, cold and salinity and application of new technologies for the improvement of stress resistance in dry areas, arid lands communities and socio-econ0mic studies, indigenous/traditional knowledge and heritage. Finally, the paper reviewed the theme of the conference and discussed the coupling relationship among the sustainable man- agement of dryland ecosystems, socio-economic factors and livelihoods. Dryland agro-ecosystems sustainable devel- opment has very close relationship with government services and their policy making. As Reynolds and LIU Jianguo in 2007 published the same ideas in Science and it explained that the sustainable development for dryland ecological environment requires livehold participation and must be considered in natural system. In particular, Reynolds dis- cussed that the sustainable development of agriculture in the arid region must the basic premise of the livelihoods of farmers to ensure that the lives of farmers and production in order to effectively implement the sustainabl
