近年来,我国林区瞭望台发展很快,全国大约2000座,有的林区已经成网(像黑龙江伊春林区已有近100座)。实践证明,瞭望台对于及时发现林火,使对森林火灾“打早打小”减少损失起到了重要作用。瞭望台观测林火,首先见到的是森林燃烧物引燃后的起烟。因此,怎样对烟的观测与了解,是瞭望台正确分析火情的关键。我们根据实践与参考国外有关资料归述以供参考。
In recent years, the observatory in our country has witnessed a rapid development. There are about 2,000 of them in the country. Some of them have become nets (like nearly 100 in Yichun Forest of Heilongjiang Province). Practice has proved that the observatory for the timely detection of forest fires, so that the forest fire “hit the early fight small” to play an important role in reducing losses. Observatory observation forest fire, the first to see is the forest fire after the ignition of the smoke. Therefore, how to observe and understand the smoke is the key to observing the fire exactly. We based on the practice and reference to foreign information for reference.
