基于遥感数据的林火监测与过火面积估算方法研究

Wild Fire Monitoring and Forest Burned Area Estimating Using Remote Sensing Data

野外森林大火每年造成巨大的经济损失和生态损失,利用遥感技术对森林火灾进行监测与灾后受灾面积的测算已成为重要的技术手段,本文使用Landsat8高分辨率的遥感影像对昆明市西山区2014年4月16日林火发生前后的植被覆盖进行了对比,运用了三种不同的分类方法对西山火灾进行了研究,统计出各种方法算得的过火面积,通过对比分析三种方法的优势与存在的问题,并对可能存在的误差进行分析。

Every year,wild forest fires caused huge economic losses and ecological loss.Using remote sensing technology to monitor forest fire and estimate disaster affected area has become an important method nowadays.In this paper,Landsat 8 high spatial resolution remote sensing image were used to compare vegetation coverage before and after the forest fire on Kunming Xishan District in April 16,2014.Three different remote sensing classification methods are used to estimate the burned area of Xishan fire,through the comparison,problems and advantages of the three methods are analyzed,and the possible reasons of errors are discussed in this paper.
