中文摘要	地球关键带(简称关键带,Critical Zone)对维系地球生态系统功能和人类生存起着决定性作用。日益严重的水土流失和喀斯特石漠化等生态环境问题主要与人类活动引起的关键带土壤物质迁移和能量交换平衡破坏有关。当前关键带土壤演化研究主要集中在关键带土壤形成机制、成土速率及其控制因素、土壤地表和地下侵蚀速率及其控制因素,以及土壤演化的控制机制等方面。然而,针对不同地质、气候和人类活动区域的关键带土壤演化及其模型预测方面的对比研究还比较少。喀斯特地区是我国生态较为脆弱的地区之一,未来还需要重点针对喀斯特和非喀斯特关键带开展土壤演化及其模型预测的对比研究,为关键带形成、演化与维持机制研究提供理论基础,并为水土流失防治和生态恢复提供决策参考。
英文摘要	The Earth's Critical Zone (abbreviated asthe Critical Zone) plays a decisive role in maintaining the function of the Earth's ecosystem and the environment for human survival. Soil,one of the key components of the Critical Zone,is tightly linked to increasingly serious eco-environmental problems since of its Human-induced imbalances of mass transfer and energy exchange,such as soil erosion and karst rocky desertification. Previous studies have provided a wealth of information about (i) the mechanism and the rate of soil formation and their controlling factors; (ii) the rate and determinant factors of soil erosion (via both surface and subsurface runoffs) ; and (iii) the mechanism and controlling factors of soil evolution. However,there has been very little research on systematically comparing field data and modeling results of the soil formation /evolution over a broad scale of from regional to continental,and much less their relations to local geological and climatic conditions as well as human activities. Karst region is one of the most ecologically fragili area in China. Such study is of particular importance for understanding soil formation,evolution and sustainability in karst and non-karst regions,which provides references in designing and implementing measures to prevent soil erosion and to restore ecosystems in karst regions.
