摘要:

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、气候和水文资源等条件也直接影响植被的生长分布及演替;本研究基于生态水文学理论,从植被变化对流域生态修复作用和水文响应等方面,系统总结了植被对流域生态水文过程的研究方法及影响,并探讨了相关生态水文模型的优势与不足,最后指出解决流域生态过程与水文过程的失衡问题是今后亟需加强的研究方向。

Abstract:

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.

Key words: vegetation, eco-hydrological processes, eco-hydrological model, watershed
