森林火灾造成了大量森林资源的损失，加剧了全球变暖。在远东地区，俄罗斯每年都会发生森林火灾，对地球环境影响很大。对NOAA AVHRR图像进行时间分析是监测全球变化的有效手段。我们利用俄罗斯远东地区10年来的NOAA AVHRR图像分析了一些热点和气溶胶。1998年是火点最多的一年，火灾的发生地是沿海地区。每年大部分火灾都发生在夏季。由于热点地区出现大量烟雾，夏季气溶胶的数量也有所增加。1998年6月由于降水较多，热点较少。1998年降水偏少，热点偏多，因此认为降水与热点数之间存在一定的相关性。
Forest fires result in loss of large quantities of forest resources, and promote global warming. In far east Russia, forest fires occur every year, and greatly influence the Earth's environment. The temporal analysis of NOAA AVHRR images is effective for monitoring the global change. We analyzed a number of hot spots and aerosols using NOAA AVHRR images for ten years in far east Russia. The year with most hot spots was 1998 and the generating places of the fires were seashore parts. Most fires occurred in summer every year. Since a lot of smoke occurs in a hot spot, the quantity of aerosol has also increased in summer. There were few hot spots in June 1998 because there was much precipitation. We consider that there is a correlation between the precipitation and the number of hot spots, because precipitation in 1998 was less than an average year and the number of hot spots was more than an average year.
