1白洋淀地区近16年芦苇湿地面积变化与水位的关系显示文摘在野外实地调查的基础上,运用RS和GIS技术通过对1987年、1991年、1996年,2000年和2003年5期Land-satTM/ETM遥感影像的解译和叠加分析,揭示了白洋淀地区16年芦苇湿地面积的变化规律,并分析水位与芦苇湿地面积关系。研究结果表明,16年间,就整个白洋淀而言,苇地变化经历了“落-起-落”的过程,水域与耕地是苇地变化的两个主要方向,苇地与水域的转变主要发生在地势较低的北部与东部地区,苇地与耕地的转变主要发生在西北与西南的地势较高地区。回归分析表明,在16年地表水位变化范围内,前2年的平均地表水位与当年苇地面积呈显著多项式关系y=-0.1573x2+215.90x-57989,决定系数为0.97;根据关系式,当地表水位低于6.9m时,苇地面积随水位的升高而增加,当水位高于6.9m时,苇地面积随水位的升高而降低。这一关系式对于利用水位来调控苇地面积,协调芦苇与其他生产生活用水的关系,促进白洋淀芦苇湿地的可持续发展与水资源的合理利用都具有重要意义。徐卫华 欧阳志云 Irisvan Duren 郑华 王效科 苗鸿 曹全虎 2005水土保持学报2005,19,4:27
