Notice of Retraction: Climate change impact on snowcoverage in mountain region

Snow dynamic change is the hot issue of global climate change. Qilian Mountain located in the southern of Hexi Corridor, and is the sensitive and key area of climatic change in arid regions. Its snow's dynamic distribution has the important meaning to climatic change's influence and the response. Under the background of the climate warming, snow area of the Qilian Mountains has changed. This paper based on EOS/MODIS, NOAA data, climate data and snow area data, which were distilled by the linear and commixtured spectrum model. Spatial-temporal distribution of the Qilian Mountain snow, climate change and its response were monitored and analyzed. Results indicated that the total snow area of Qilian Mountain is waveform changes between 1997 and 2006, and has a linear increasing trend, but in the eastern and middle area of the Qilian Mountains, snow area has a reducing trend. Comparing climatic change and snow area change, we can found that the snow area of the eastern was consistent with the local climatic conditions, therefore, the eastern snow of the Qilian Mountains were mostly influenced by local climatic conditions.
