| 摘 要： | 红碱淖是我国面积最大的沙漠淡水湖泊, 也是全世界最大的遗鸥繁殖与栖息地, 对该地区水面面积变化进行动态监测分析具有重要意义. 利用TM、 中巴资源卫星影像对红碱淖水面面积进行解译, 结合前人的研究成果, 对红碱淖水面面积的动态变化进行了模拟, 分析了引起红碱淖水面面积急剧萎缩的原因. 结果表明: 20世纪90年代以来红碱淖水面面积在大幅度萎缩, 水位急剧下降. 红碱淖水面面积急剧萎缩是气候变化和人为影响因素综合作用的结果, 可能的影响因素有气候变化、灌溉用水、生态环境建设、煤矿开采用水排水和水源地开采等5个方面, 其中上游河流截流是主要原因.

| Abstract: | Hongjianlao Lake is the biggest desert freshwater lake in China;it also is the biggest propagation and habitat of Larus relictus in the world. The change of water surface area of the lake plays an important role in protecting environment. After collecting data through interpreting Landsat TM and China and Brazil Earth Resource Satellite images and reading foregone papers, the change of water surface area of Hongjiannao Lake has been simulated with a conic, and the reason of the lake rapidly shrinking has been analyzed. The analyses show that the water surface area of Hongjiannao Lake has been shrinking and the water level has been falling quickly since the nineties of the twentieth century. It is resulted from the synthetically action of climate change and contrived effects, such as, irrigation, environment restructure, coal mine exploitation and water resource utilization. Intercepting upriver stream is the main cause. |
