Maqu wetland is located on the northeastern edge of the Qinghai-Tibet Plateau. As one of the important water conservation and recharge areas in upper Yellow River, it is of great significance for regulating the Yellow River water and sediment, maintaining biodiversity and regional ecological balance and to achieve sustainable socioeconomic development. In order to analyse the dynamic characteristics and regional differences of Maqu alpine wetland systems during the past 20 years, in this paper, 1990, 2000 and 2010 series of Landsat satellite data as the main data source, using remote sensing and GIS spatial analysis technology, adopting the method of multivariate statistical classification, dynamically monitored the distribution pattern changes of Maqu wetland. The results showed that: Maqu wetland area was overall in a downward trend in recent 20 years; in 1990, 2010, the wetland area of 1151.7km2, 1049.32km2 respectively, the area reduced by 02.38km2, the average annual decline rate was 0.37%. In the period from 1990 to 2000 annual average shrinkage rate was 0.43%, significantly faster than the 0.31% of the 2000 to 2010 period. Analysis showed that global climate change and increasing human activities were the main drivers of the wetland ecological environment deterioration.Keywords
