中蒙边境地区草原火时空分布特征分析
Spatiotemporal Characteristics of Grassland Fire in China-Mongolia Border Regions
摘要
Abstract
Grassland fire is one of the serious natural disasters suffered both in China and Mongolia.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.The study results indicated that recent 15a,the burned area distributed widely 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 ten days change,the period that biggest burned area takes place in Mongolia is from April to June,and in East Ujimqin from October to next year April.关键词
