摘要
基于1975年MSS、2000年ETM^＋以及2006年CBERS一2卫星遥感数据，对黄淮海流域1975～2006年31a来的湿地面积变化进行了研究。调查结果表明，黄淮海流域湿地总面积在1975～2000年间呈稳步下降趋势，总面积净减了1388．50km^2；2000～2006年间，湿地面积从80762．13km^2增加到了81825．15km^2。针对黄河流域湿地表现出的逐年萎缩变化趋势分析得出：工作区内的地质背景和气候因素决定了湿地的总体分布和变化态势，而人类因素在湿地变迁的过程同样起到了至关重要的作用。
Based on MSS, ETM ^＋ and 2006 satellite CBERS -2 satellite images obtained in 1975, 2000 and 2006, the authors studied the changes in wetland areas of the total basin during the 31 years of 1975 -2006. The survey reveals that the total area of the wetlands steadily decreased from 1975 to 2000, with the total reduced area being 1 388.50 km^2. The results also show that, from 2000 to 2006, the area of the wetlands increased from 80 762.13 km^2 to 81 825.15 km^2. The shrinkage of Yellow River Basin wetlands year by year has led the authors to believe that the geological background and climate factors of the working area determine the overall distribution and changes of the wetlands, and that human factors also play an equally important role in the variation of the wetlands.
