摘　　要：随着全球气候变化的日益凸显,旱区农业和生态系统可持续性发展越来越受到世界各国政府和生态学家的关注。本文综述了2013年10月14—18日在兰州大学举行的干旱农业和生态系统可持续性国际会议全部28场学术报告,围绕"旱区雨水资源高效利用与生态系统可持续管理"的主题,分别从干旱农业面临的机遇和挑战、雨水资源高效利用、旱区生物多样性保护、生态信息系统构建、生态系统可持续管理和加强发展中国家之间的国际合作等几个方面进行了总结。文章最后围绕生态系统圈层管理理论,总结了最近几年在旱区农业水资源利用和生态系统管理方面的最新进展,构建了生态保育和农业生产之间的耦合关系图,为气候变化下旱区粮食安全、农户生计改善、生态系统可持续管理和社会经济协调发展提供理论依据。With the increasing occurrence of global climate change, dryland agriculture and eco- system sustainability have been receiving more attention from the governments and ecologists worldwide. This paper reviewed all the 28 presentations in the International Workshop on Arid Agriculture and Ecosystem Sustainability held at Lanzhou University from 15 to 18 October, 2013. The presentations focused on the workshop theme of ＂efficient use of water resources and sustainable management of ecosystem＂. Major aspects were summarized in this workshop such as oppor- tunities and challenges in dryland agriculture, efficient utilization of rainwater resources, conser- vation of biodiversity in dry areas, construction of bio-information system, sustainable ecosystem management, and enhancement of international cooperation among developing countries. Finally, on the basis of stratified feature and distinct theory of ecosystem management, we summarized the progress in agricultural water resources utilization and ecosystem management in dry areas in recent years. A conceptual diagram regarding coupling relationship between ecological conservation and agricultural production was constructed. It was aimed to provide potential theoretical evidence for food security, farmers＇ livelihood improvement, sustainable ecosystem management and harmonious socio-economic development under the background of climate change.
