流域生态水文过程与植被响应研究进展

生态水文学是流域水资源管理的理论基础.流域生态过程与水文过程间的关系是当前生态水文学研究的重点之一,也是实现生态文明建设的重要科学举措.植被对流域的生态水文过程有着密切联系.流域内的植被不仅提供减少空气污染和能源消耗、改善水质等生态服务,还通过截留、蒸散、下渗等作用维持流域内水资源与土壤资源之间的动态平衡.流域内土地、...

Review of Watershed Eco-hydrological Processes and Vegetation Responses

Ecological hydrology is the theoretical basis of river basin water resources management. The relationship between ecological and hydrological process is a research emphasis of eco-hydrology, which is a scientific method to realize the ecological civilization construction. There is a close relationship between vegetation and eco-hydrological processes. Vegetation in the basin can alleviate air pollution, reduce energy consumption and improve water quality. In addition, it can maintain the dynamic balance between water resources and soil resources in the basin through interception, evapotranspiration and infiltration. Similarly, the conditions of land, climate and water resources can directly affect the growth, distribution and succession of vegetation. Based on the theory of eco-hydrology, in terms of the effect of vegetation on watershed ecological restoration and the response of vegetation to watershed hydrology, we systematically summarized the impacts of vegetation on the ecological and hydrological processes and discussed the advantages and disadvantages of relevant ecological and hydrological models. Finally, we pointed out that it is an urgent research direction to solve the imbalance between the ecological process and hydrological process.
