【摘要】：分析了近千年淮河流域河湖水系的自然演变以及人类活动的扰动,深入探讨了其成因。研究表明:目前淮河流域河湖水系连通格局是人类在抵御黄河洪水和泥沙入侵的抗争中,遵循自然规律的同时兼顾漕运、灌溉等社会发展所需而构建的防洪、排涝、冲沙、灌溉、供水等的工程体系。流域主要干支流和湖泊连通基本受人工所控,自然-人工河网交织,河流-湖泊水量交换频繁,入江入海水道基本畅通,并与黄河、长江、海河等各大水系连通,基本解决了河水出海无路,洪涝灾害频发的问题。河湖水系连通在一定时期内对稳定淮河流域社会安定团结、推动经济发展起着积极作用,但也不可避免地对流域生态环境产生了一定的负面影响。水系连通下流域水资源演变规律、环境生态效应以及对社会经济布局的影响等研究是亟待解决的关键科学问题。
[Abstract]:The natural evolution of the river and lake water system in the Huaihe basin and the disturbance of human activities in the last 1000 years are analyzed. The study shows that the current connection pattern of the river and lake water system in the Huaihe basin is the need for the human being to resist the the Yellow River flood and the invasion of the sediment, and it is necessary to follow the natural law and give consideration to the social development of water transport and irrigation in the same time. Flood control, drainage, sediment discharge, irrigation, water supply and other engineering systems. The main branch stream and lake connectivity are basically controlled by artificial, natural artificial river network interlacing, river and lake water exchange frequently, the river entering the sea waterway is basically unimpeded, and connected with the Yellow River, the Yangtze River, the Haihe River and other major water systems, and basically solved the river water without road, flood and waterlogging disaster. The river lake water system connectivity has played a positive role in stabilizing the social stability and unity of the Huaihe basin and promoting economic development in a certain period, but also inevitably has a certain negative impact on the ecological environment of the river basin. The water resources evolution law, the ecological effect of the environment and the influence on the social and economic layout under the water system connected to the river system Research is the key scientific problem to be solved urgently.
