Abstract

In view of the grassland fire occurred in 3 banner of East Ujimqin banner in China and adjacent Mongolia as research area, the spatiotemporal characteristics was analyzed by GIS space analysis method and using the 2000-2014 MCD45A burned products,MOD13Q1 products data and meteorological data.The results indicated that recent 15year, the burned area distributed widly and 95% of the total area of the study area located in the territory of Mongolia, with the highest rate of 7 in Khalkhgol . But East Ujimqin Banner has not happened it. The annual variation trend of the burned area showed that the downward trend happened in 2000 - 2008, and upward trend in 2008 - 2014.Known by analysis of influencing factors of grassland fire that large burned area and high frequency in high NDVI area, opposite in lower NDVI area; The interannual burned area variation with precipitation has inversely proportional,with temperature has direct proporation.
