当代科学和社会视角下的地理学

地理学长期关注的人类与环境之间的相互关系，以及地球表层重要特征及其空间结构变化，正逐渐成为当代科学和社会的核心议题，直指今天大众和决策者的紧迫关切。然而，社会对地理学的认识还很不充分，以至于在应对环境变化、资源稀缺、发展失衡、国家冲突等重大问题上受到很多限制。因此，很有必要以当代科学和社会的视角来重新认识地理学。笔者以全球变化和可持续发展的新视角，论述了地理学的研究对象、认识途径、核心概念、在科学知识体系中的地位、在满足社会需求中的作用，以及在国家科技发展中的作用。

On geography in contemporary scientific and social perspectives

The relationship between human beings and the environment, and the important features of the Earth's surface and their spatial structural changes longterm concerned by geography, are becoming the core issues of contemporary science and society, and directing at today's pressing concerns of general public and policy makers. However, the understanding of society to geography is far from sufficient, so that the responses to such major issues as environmental change, resource scarcity, unbalanced development and national conflicts subject to many restrictions. Therefore, it is necessary to rediscover geography in the new perspective of contemporary science and society. With new perspectives of global change and sustainability, this article discusses the study objects, research approaches, core concepts, position in scientific knowledge system, and roles to meet social needs and in national science and technology development of geography.
