摘要
以MODIS数据为主要数据源,结合土地利用现状数据,通过ENVI软件数据处理,优化火点识别算法和提取流程,提取区县范围内的秸秆焚烧火点,并通过多年数据对比,分析秸秆焚烧点的时间分布和空间分布特征。试验表明,MODIS数据能有效地提取火点,为秸秆焚烧管控提供可靠的技术手段,对生态文明建设具有一定的实用价值。
With MODIS data as the main data source, combined with the current land use data, through ENVI software data processing, optimize the fire point identification algorithm and extraction process, extract the straw burning fire point in the region and county, and through the comparison of many years of data, analyze the time distribution and spatial distribution characteristics of straw burning point, the test shows that MODIS data can effectively extract the fire point, for straw burning management and control. It is of practical significance to provide reliable technical means for the construction of ecological civilization.
