Issues and prospects of belowground ecology with special reference to global climate change

The theory of ecology is based on over 100 a of research and investigation, all centered on aboveground patterns and processes. However, as contemporary ecologists are increasingly acknowledging, belowground structures, functions, and processes are some of the most poorly understood areas in ecology. This lack of understanding of belowground ecological processes seriously restricts the advance of global change research. The interdisciplinary field of belowground ecology began to flourish in the 1990s, along with the expansion of global change research, and quickly gained momentum. Belowground ecology aims to investigate belowground structures, functions, and processes, as well as their relationships with corresponding aboveground features, emphasizing the responses of belowground systems under global change conditions. Key research areas include root ecology, belowground animals, and soil microorganisms. This review summarizes and analyzes the relationships between aboveand belowground ecosystems, root ecology, root biogeography, belowground biodiversity, as well as research areas with particular challenges and progress. This commentary emphasizes certain theoretical issues concerning the responses of belowground processes to global change, and concludes that belowground ecology is a critical research priority in the 21st century.

Lithological architecture, geological processes and energy-field environments are major factors for the formation of hydrocarbon reservoirs

The formation of hydrocarbon reservoirs is controlled by three major factors: lithological architecture, geological processes and energy-field environments. Among the three major factors, lithological architecture provides the storing medium for hydrocarbon; geological processes include hydrocarbon generation, migration, accumulation, preservation and modification; and energy-field environments refer to the various geothermal and geodynamic forces that affect the lithological architecture and drive the geological processes. In this study, we take Kela-2 and Sulige gas reservoirs as two examples to study relationships among the three major factors, and explain how these factors influence the scale and quality of hydrocarbon reservoirs.     

关于模糊更新过程的一个定理及其应用

自1965年Zadeh提出模糊集的概念以来，各种模糊理论的研究蓬蓬勃勃地开展起来．在概率统计方面，1981年Kwakemaak提出了模糊随机变量的定义，1982年Kruse研讨了独立同分布的模糊随机变量序列的强大数定律．本文研究的是更新过程的更新比率，证明了一个重要定理，提供了应用的例子．
