摘要
统计2001-2012年湖南省卫星遥感监测热点数目,结合各时期降水量,对数据进行分析,结果表明:热点数与降水量呈负相关关系;与野外用火多少呈正比例关系。再与湖南省1983-2005年大范围山火发生记录进行比较,最终得出结论:湖南电网山火高危期有6个,按平均每天热点数的多少和危险系数的大小从高到低排序,依次为:清明节、春耕、春节、秋收、秋后烧荒以及中元节,其中前3者最为危险。
Hotspot number between 2001-2012 in Hunan province collected using remote sensing satellites was counted and analyzed combined with precipitation at different time. The re suits showed that hotspot number was negatively related to pre eipitation and positively to campfire. And,compared to record of wide-range wildfire in Hunan province between 1983-2005,it was concluded that there were six high wildfire risk period, according to average hotspot number and risk coefficient from highest to lowest were Tomb-Sweeping Day, Spring Ploughing： Spring Festival, autumn harvest, burning after autumn harvest and Ghost Festival,among which the former three was of highest risk.
