Study on Spatio-Temporal Changes of Wetland Landscape Patterns in the Modern Yellow River Delta

Abstract

The wetland distribution in the modern Yellow River Delta is extracted by using a combination method of supervised classification based on the Landsat TM images in 1991, 2001 and 2011. The changes of wetland were analyzed from landscape index in the paper. The result shows that the area of natural wetland degrades, while the area of artificial wetland increases from 1991 to 2011. The transfer trajectory of spatial centroids of the wetland shows that it shifts towards southeast. Man-made driving forces are the main factors that cause natural wetlands degrades.
