地表过程研究进展与趋势

地表过程复杂多样、涉及广泛。针对当前地表过程研究现状,从地球系统科学和全球变化的视角讨论了与地表过程相关的一些概念及研究内涵。在分析单要素地表过程和多要素地表过程的基础上,从研究内容的综合性、多国合作的国际性、针对区域突出问题的区域性、以过程变化为核心的动态性及研究方法的多样性等方面论述了地表过程研究的特点,总结性地给出了国内外研究的总体趋势。在上述分析基础上,进一步从国际科学发展趋势、国家需要和信息、技术等方面分析了中国地表过程研究所面临的机遇;从多学科交叉、自然与人文过程的定量与有机耦合等方面讨论了地表过程研究所面临的挑战。

Studies of Earth Surface Processes: Progress and Prospect

The Earth (land) surface processes are very complex. The current status of the study of the land surface processes is reviewed, and some concepts and connotations are discussed. Based on the analysis of the study focused on single-factor and on multi factor Earth surface processes, respectively, the characteristics of the study of the Earth surface processes are discussed from integration of research content, international cooperation of multi national, regional characteristics focusing on outstanding problems in the area, the dynamics of the core of the earth surface processes change, and the diversity of research methods. The overall prospects of the study of the Earth surface process are summarized, includeing that the studies of the Earth surface processes will be the focus and hot topics of future study of Earth system science, the studies of key processes controlling climate change are the important issue of study of the Earth surface processes, the studies of the interfaces between different components within the Earth surface system are the important entry points, the coupling study of natural processes and human processes will be important direction, advanced technology and facilities have increasingly prominent supporting role, and networking and cross-integration research will be more important organizing mode in the study of earth surface processes. The opportunities of the studies on the Earth surface processes in China are pointed out from the international scientific research trends, national needs, information and technologies. The challenges facing the study of the Earth surface processes are discussed from cross study of multidisciplinary, quantities and coupling study of natural and human processes, theory and method of earth surface systems study, three-dimensional observation-data assimilation-model simulation-decision support integration.
