中文摘要: 以DVB-S下发的气象卫星AVHRR遥感资料为基础,根据下垫面性质把鹤壁分成不同火点判识子区,通过对卫星火点监测资料和实际火点资料统计对比分析,确定每一子区不同时次的精细门槛值,并利用1∶5×104大比例尺行政数据集对火点进行精确定位,在鹤壁地区2004和2005年秸秆焚烧监测应用中取得了良好效果,为政府部门及时准确掌握全市秸秆焚烧情况,提高火情监测能力和监督检查效率提供了重要科学依据。
中文关键词: AVHRR，秸秆焚烧，精细门槛值，火情监测
Abstract:On the basis of the remote sensing data derived from meteorological satellite AVHRR through DVB-S,Hebi area is divided into several sub-areas for identifying fire points according to surface characteristics.By means of statistics and contrasting analysis of the satellite-monitored fire point data and actual fire point data,the refined threshold values in each sub-area at different time are determined.Then the administrative position of the fire points are precisely located by using 1∶50000 scale administrative data set.This method was utilized in the monitoring of straw stalk burning in Hebi area in 2004 and 2005 and obtained very good effect.It provided an important scientific basis for the government to keep abreast of the straw stalk burning situation in the whole city promptly and accurately,and improve the fire monitoring ability and inspecting efficiency as well.
