摘要
地质科学研究要以人为本，从可持续发展出发，开拓地质多样性，有所为有所不为．中国黄土研究经历了发现研究、比较研究和目的研究３个层次阶段，今后需要加强目的研究．中国已有条件从黄土所保存的各种信息，以揭示新生代以来全球干旱化的机制、规律和人类活动影响为目的，从区域性走向全球性研究，提出黄土“地质生态系统”研究的概念。基础研究方面，讨论了 １）黄土序列连续性和间断性的间断平衡（ＰＵＮＣＴＵＡＴＥＤ ＥＱＵＩＬＩＢＲＩＵＭ）问题。２）黄土全球分布形成机制一元论问题；３）黄土地貌形态与地壳运动表现问题。应用研究方面，讨论了１）健康与黄土区域地球化学与地质生理学（ＧＥＯＰＨＹＳＩＯＬＯＧＹ）问题；２）建设城乡与黄土地质生态结构问题；３）农业与黄土区域生态系统管理评价（ＲＥＧＩＯＮＡＬ ＥＣＯＳＹＳＴＥＭＡＳＳＥＳＭＥＮＴ）。认为在黄土研究中会遇到社会和技术发展方面的挑战，但关键是科学工作者自己的挑战。
Geological studies should focus on human beings, with consideration of sustainable development diversifying study areas, and selecting what should be done. The Chinese loess research underwent fore stages: finding, comparison, and destination, and in the future we need to pay more attentions to the destination studies. Now, based on the various paleoclimatic information documented in the Chinese loess, Chinese scientists have targeted their studies on understanding the mechanism of global aridification and the human impacts on environment. They also broadened their studies from regional to global scales and proposed the concept of 'Geoenvieonmental System.' In the respect of fundamental research, they have discussed: (1) the continuity and hiatuses of loess-soil sequences (punctuated equilibrium); (2) the monism of loess formation and distribution on global scale; and (3) the relationship between the loess geomorphology and neotoctonics. Whereas in the respect of applied field, they discussed: (1) the relationship between the human health and the geophysiology in loess regions; (2) the problem between the urban development and the loess engineering; and (3) and the relationship between agriculture and the regionalecosystemassement, They further argued that the loess research have been challenged by the development in both social and technical fields, anyway, the most important challenge is from themselves.
