Meteorological evaluation of ecological quality in Mt. Qomolangma region based on satellite data

The present study evaluated the ecological quality of Mt. Qomolangma region in 2010 by establishing the composite index of meteorological evaluation. Five indices including humidity, vegetation coverage, water bodies density, soil degradation and disaster were calculated based on the combined EOS／MODIS satellite data and meteorological data which included satellite data of MOD13A3 in 2010 and MCD12Q1 in 2009 and atmospheric temperature (℃), precipitation (mm), relative humidity (%), wind speed(m·s-1) and pressure (Pa) in 2010 collected from 5 stations in Mt. Qomolangma region and 3 stations surrounding the region. The results showed that composite index of meteorological evaluation can improve the efficiency of the ecological quality evaluation and well describe ecological quality of Mt. Qomolangma region from both geographical distribution and dynamics which can be used to monitor the dynamics of ecological environment. The application of this method could provide a useful tool for scientific evaluation of environmental changes and conduct a scientific basis for ecological function division and ecological environment protection in this region.
