| Abstract: | Based on the landscape ecology principles,remote sensing(RS),geographical information systems (GIS) and other technical means,the remote sensing images of 1976,1986,2000 and 2008 are processed and analyzed.The results show that the total area of wetlands decreased by 8.5% in the modern Yellow River Delta from 1976 to 2008.The area of natural wetlands decreased by 44.5% from 1976 to 2008.The area of reed wetland decreased greatly too.From 1976 to 2008,it decreased to 23.0%.On the contrary,the area of constru... |
