摘　　要：利用手持式测树枪测角、测距功能,根据三角函数和相关数学模型计算提出林火蔓延距离和速度、火焰长度、火场周边长、过火面积等林火行为参数的精准观测方法,实现了林火行为参数观测数字化、内外业一体化。在试验区开展精度验证,结果证明:双站测树枪观测林火蔓延距离的精度为99.28%,火场周边长测量精度为99.29%,过火面积测量精度为98.26%,测树枪的观测精度满足林火观测要求。The study present a precise measure method about forest fire behavior parameter such as forest fire spread distance and speed, flame length, fire scene perimeter, burned area and realized forest fire behavior parameter observation digitization and field surveying and interior work integration, which counting result based on trigonometric function and relevant mathematical models through applying angle measurement and distance measurement functions of electronic forest measurement gun. Through precision test that fire spreading fire scene perimeter and burned area in the experiment area by electronic forest measurement gun, the result suggest that double Forest Measurement Gun accuracy was 99.28% to observe fire spreading distance,the accuracy was 99.29% to observe fire scene perimeter, the accuracy is 98.26% to observe fire scene area. The results indicate that the instrument can meet the requirements of forest fire observation.
