| 摘 要： | 土壤圈是地圈系统的重要组成部分，它处于地圈系统，即气圈、水圈、生物圈与岩石圈的交界面，是最活跃、最富生命力的圈层。土壤圈的物质循环是全球变化中物质循环的重要内容，因此，研究土壤圈及其物质循环的结构与功能，对全球变化，特别对全球土壤变化有密切关系。土壤圈在全球土壤变化中的研究内容包括：土壤圈与地圈各圈层的物质循环；水土资源的时空变化；土壤肥力变化与农业持续发展，区域治理与环境建设等，这些都是全球土壤变化，特别是中国全球变化的主题，应引起高度重视。

| Abstract: | Pedosphere is an important component of the geospheric system. It is situated at the interface of the geospheric system, i.e., atmosphere, hydrosphere, biosphere and lithosphere and is the most active and vital sphere. The material cycling in pedosphere is an important portion on the research of the material cycling in global changes. Therefore, studies on pedosphere and on the structure and functions of the material cycling in pedosphere have a close relation to global changes, particularly to global soil changes. The research scope and contents of pedosphere in global soil changes include material cycling in pedosphere and the other geospheres; temporal and spatial variations of water and soil resources; soil fertility changes and sustained agricultural development; regional rehabilitation and environmental construction etc.. They all are the themes of global soil changes and in particular of the global changes in China, and hence deserve our high attention. |
