三峡水库水位涨落带的土地资源及其开发利用

ON LAND RESOURCES OF WATER-LEVEL-FLUCTUATING ZONE IN THE THREE-GORGE-RESERVOIR AND THEIR EXPLOITATION

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，夏半年出露水面为陆，是一种独特的湿地生态系统。在夏半年，涨落带出露土地面积大，可利用基础好；加之成陆期较长，与同期丰富的光热水资源构成优势组合，使涨落带土地资源具有较高的生产潜力。因此，应重视涨落带土地资源的研究和利用。

After the compietion of the Three-Gorge-Reservoir in Yangtze River,a water-level-fluctuatingzone will be formed along both banks of a section of the river in the reservoir. The zone will be a typeoi land resources with many functions for being a water area through a winterhali- year and a land areathrough a summer-half-year. The zone will be of a special value to utilization because there will be notoniy an area of hundreds of square kilometers and a goed basis for exploitation,but aiso a longer periodbeing a land and a better realignment of land resources, sunlight energy,radiant heat and water re-sources in this Deried. Therefore,it is important to pay a greater attention to researches on land re-sources in the zone and their exploitation.
