| 英文摘要 | environmental problem in and zones. The change in the eco-hydrological processes is the basic cause responsible for such a problem. The study on the eco-hydrological processes in and zones has become a forefront and focus of the eco-environmental research. Recent studies on eco-hydrological processes in and zones show that the primary vegetation pattern and its eco-hydrological effect are of the most stable state of the ecosystem in and zones. Special water absorption ways of plants in and zones and the hydraulic lift and reverse hydraulic lift functions of some plants are the key mechanisms to maintain the stability of the ecosystem in and zones. In the case of water shortage, ensuring ecological water requirement and maintaining proper ecological ground- water table are the prerequisite to keep healthful operation of the ecosystem in and zones. The paper reviews some advances in the study of eco-hydrological processes in and zones. It puts forward the concepts of critical ecological water requirement, optimal ecological water requirement and saturated ecological water requirement, and discusses their determination methods. It also emphasizes that the studies on natural vegetation pattern and eco-hydrological effect, on plants with hydraulic lift function, on water sources for plant absorption, on ecological water requirement and ecological groundwater table for different plant species should be strengthened to determine the species composition and pattern suitable for the restoration and reestablishment of vegetation in different and zones in China. |
