黄骅湿地的动态变化及保护对策

摘要

To analyze the dynamic change and the changing cause of wetland in Huanghua from 2001 to 2009, the Landsat satellite images of 2001, 2005 and 2009 was interpreted and processed by ERDAS and ENVI; and relative data was obtained by the method of Change Detection to observe the dynamic change and transforming situation. The results showed that the area of wetland was reducing seriously, and some was converted to artificial wetland. Based on the phenomenon, some protective measures were proposed.%为了研究黄骅湿地2001-2009年的变化情况及变化原因,运用ERDAS和ENVI对2001、2005、2009年美国Landsat卫星影像进行影像判读和数据处理,利用Change Detection方法得到相关数据,探讨其动态变化状况及转化情况.结果表明,黄骅湿地不断减少,其中自然湿地面积大量减少,并部分转为人工湿地.依据这一现象提出了一些保护措施.
