要计算潜在火场的近似面积,就要考虑火场的形状。对于在连续均匀的可燃物和相同地形上蔓延的林火来说,风速在确定其火场形状方而起着重要作用。在静风条件下,火场形状趋向于圆形。如果风向不变,基本 To calculate the approximate area of ​​a potential fire, consider the shape of the fire. For a forest fire that spreads over a continuous and uniform combustible and the same terrain, the wind speed plays an important role in determining the shape of its field. Under static wind conditions, the shape of the fire tends to be circular. If the wind does not change, basic
