| 摘 要： | 以山西省2005—2008年卫星遥感热点为研究对象,通过对卫星遥感监测的热点情况与同期气温、降水和大风时数的相关分析,建立了利用月平均气温、月降水量、卫星遥感月热点监测个数和卫星遥感下垫面状况等资料反演的森林火险等级预警模型,以期提高森林火险等级预报的准确性。

| Abstract: | The article takes the hotspot monitoring data of the remote sensing during 2005—2008 as a study object.Then,the article analyses the relationship between the hotspot data and the meteorological parameters including temperature,precipitation and gale hours,which are in the same time period.Finally,a forest fire danger level warning model was built,and the parameters for model construction includes the monthly mean temperature,the monthly mean precipitation,the monthly hotspot monitoring of the remote sensing and the underlying surface situation of the remote sensing.The warning model can improve the forest fire danger level warning accuracy rate greatly. |

| Keywords: | remote sensing hotspot monitoring temperature precipitation gale hours early warning |
