摘要
三峡大坝建成后,将在库区两岸形成永久性的水位涨落带。涨落带冬半年为水域,夏半年出露水面成陆,是一种具有多功能的土地资源类型。在夏半年,涨落带成陆面积大,成陆期较长,与同期丰富的光热水资源构成优势组合,使涨落带土地具有较高的生产潜力。对三峡库区水位涨落带土地资源的质量、数量和分布特点进行了分析,在此基础上提出了合理利用的设想。
After the completion of the Three Gorges Reservior in Yangtze River,a water lever fluctuating zone will appear along both banks of the section in the reservior.The zone will be a type of land resources with many functions,being a water area through the winter half year and a land area through the summer half year.The zone will be of special value to utilization because there will be not only a land of about one hundred square kilometers for a considerable period of time in a year,but also a better realignment of land resources,sunlight energy,solar radiant heat and water resources through the summer half year.This paper analyses the quality,quantity and distribution of the land resources of the water level fluctuating zone in the Three Gorges Reservior and puts forward tentative ideas of the rational use of the land resources.
