变化环境下鄱阳湖水文水资源研究与应用

Research and Application of Hydrology and Water Resources under Changing Environment in the Poyang Lake Basin

摘要: 在全球变暖和人类活动日益增强的背景下，随着人口增长和经济社会的快速发展，人类活动对水文圈的扰动愈加剧烈，探讨变化环境下气候变化和人类活动对流域水循环和水资源的影响，已经成为研究的热点和重点。鄱阳湖作为全国最大的淡水湖泊，地处长江干流与五河来水的汇合地带，受特殊的地理位置、自然条件及区域经济社会发展的影响。目前湖区的自然灾害仍然频繁，防洪减灾、水资源综合利用、水资源与生态环境保护等任务仍十分繁重。近年来开展了变化环境下鄱阳湖水文水资源的研究工作，本文综述分析了主要研究内容、关键技术和取得的创新成果；以及在《长江流域综合规划》、《鄱阳湖区综合规划》和鄱阳湖水利枢纽工程的论证、规划和设计中的应用。

Abstract: Under the background of global warming and increasing human activities, along with rapid popu-lation growth and development of economic and society, the hydrological circle has been disturbed more intensely by human activities, which has already become a research focus and key point to investigate the impact of climate changes and human activities on water cycle and water resources. Poyang Lake, as the largest freshwater lake of China, is located at the confluence zone of Yangtze River trunk stream and five major rivers and is affected by the special geographical location, natural conditions, and regional economic and social development. At present, the lake area is still bearing frequent natural disasters and the tasks of flood control, disaster mitigation, com-prehensive utilization of water resources and ecological environmental protection are still very tough. The research projects of hydrology and water resources under changing environment in the Poyang Lake basin were carried out in last ten years. The main research contents, key technologies and innovative achievements of these projects were summarized and applied in the “Comprehensive Plan of Yangtze River Basin”, “Comprehensive Plan of Poyang Lake Area”, and the argument, planning and design of Poyang Lake hydro-junction project.
