林火卫星遥感监测及早期报警技术研究

Study on Monitoring and Early Alarm Technique of Forest Fire Using Satellite Data

以我国林火发生率较高、卫星监测林火难度较大的西南林区为试验区，为大幅度提高林火报准率，开展了微机图像处理技术、地理信息系统（ＧＩＳ）、森林火灾的分布规律、ＡＶＨＲＲ林火信息提取技术和专家系统应用等研究。介绍了该项目的研究方法，叙述了研究成果的技术原理，展望了今后研究的主攻方向。

Experimental area of the stUdy is in forest area in southwest china where forest fires occured frequently and monitoring them was quite difficult. Principal purpose of the study is to increase the accuracy Of discovering forest fire. The study involved imagery processing technique on microcomputer, geographic information system (GIS) and distribudtion law of forest fire as well as information extract technique of forest fire from NOAA-AVHRR data and application of eXpert system (ES). The paper introduced research methods of the study, descriped principle of its achievements and further prospected main research aspectS in this field.
