摘要
湖泊蕴含丰富的淡水资源,是区域发展的重要支撑。气候变化和人类活动加剧全球水资源时空分布差异,伴随越发频繁的湖泊洪水和干旱问题,影响区域经济社会用水安全和湖泊生态系统健康。湖泊流域是一个相对独立完整的地理单元,具有明确的水文边界,因此,一直以来是水文研究的理想区域。针对21世纪以来湖泊流域新呈现的水文问题,基于文献调研,结合长江中游鄱阳湖流域案例,重点就流域水文极值与湖泊洪旱、湖泊水文对流域植被变化的响应、湖泊流域系统水文水动力集成模拟、湖泊流域水平衡演变及未来变化趋势预测等若干水文问题的研究现状和问题进行阐述,提出未来拟着重研究的若干主题。研究可望丰富流域水文学和湖泊水文学内容,对相关学科未来发展提供参考。
Lakes provide important freshwater resource for regional development. Climate change and human activities significantly affect the spatial and temporal distribution of water resource at the global scale. Consequently, frequent floods and droughts occur in lake catchments, impacting local water security and aquatic ecosystem health. Lake catchment is a relatively independent geographic unit, and thus, has been used as an ideal area for hydrology research. Focusing on several new hydrological issues in the 21st century, this article reviewed up-to-date hydrology research status in topics including extreme hydrological events, hydrological impacts of land cover changes, integrated modelling of lake catchment, evolution and future projection of water resource availability of lake catchment. Exemplified in Poyang Lake catchment, a large freshwater lake in the middle Yangtze River, research gaps are identified and future directions are suggested. This article may enrich the research context of catchment hydrology and limnology, and may be of reference value to the future development of relevant science disciplines.
