长江口盐水入侵研究

根据长江口盐水入侵的历史和现状 ,指出流域大量蓄引提供水工程、北支入流条件恶化、湖泊和河槽调蓄能力减弱等是导致长江口盐水入侵加剧的主要原因 ,而南水北调工程将使入海径流减少以及北支河势继续恶化、海平面上升加剧 ,河口整治与开发是今后所面临主要的问题。在总结长江口盐水入侵研究现状的基础上 ,提出了一些初步想法。

Salt water encroachment at the Yangtze River Estuary

Based on the history and present situation of salt water encroachment at the Yangtze River Estuary, the causes of aggravation of salt water encroachment at the Yangtze River Estuary are analyzed, including the construction of water storage, water diversion, and water intake projects, the deterioration of north tributaries, and the decrease of water diversion and storage capacities of lakes and river channels. Furthermore, the South-to-North Water Transfer Project will lead to the decrease of runoff to seas, further deterioration of the regime of the north tributaries, and the rise of the sea level. Finally, some preliminary suggestions are proposed.
