摘要
根据新近土壤物理学研究进展,论述了土壤物理学在土壤学中的定位和在自然科学和社会可持续发展中的地位;从研究的对象、内容、尺度、理论、方法和测定技术方面,阐述了土壤物理学的研究现状;分析了新形势下土壤物理学面临的挑战;提出了我国土壤物理学研究未来10年5个方面的主要任务,即:农业可持续发展中的土壤物理问题,土壤结构形成过程及其稳定性,土壤中能量传输和物质运移过程,土壤性状及过程的时空变异与尺度转化,土壤物理过程与土壤化学、土壤生物过程的耦合。
Soil physics is an essential discipline of natural sciences, and it plays important roles in sustainable agriculture and environmental protection. In this review, we briefly examined the current status and trends of soil physics in terms of new theories, new technologies, and research focuses at different scales. We also brought up the significant chal-lenges facing current soil physics researches. Finally we proposed five major topics for soil physics research in China in the next decade： The role of soil physics in sustainable agricultural development, soil structure formation and stability, mass transport and energy transfer in soil, spatial and temporal variation and scaling of soil physical properties and processes, and the coupling mechanisms of soil physical, chemical, and biological processes.
