You can find a tree stump in the forest, and identify the direction according to its annual rings, because its annual rings are always narrow and wide on the south side; you can observe an independent tree with luxuriant foliage on the south side. The northern side is sparse.
You can identify the direction based on the ant's cave. Because the ant's hole is mostly south-facing; in places where there are many rocks, you can also look for an eye-catching rock on the north side of the rocky side, with the dry bald side on the south side.
If you are on a starry night, you can identify the direction according to the stars: first find the Big Dipper in the sky, find the sixth and seventh stars along its “handleâ€, and determine the mathematical principle of a straight line based on two points. The two stars are connected in a straight line, and a brighter North Star is found on the extension of this connection. From the “sleeve handle†to the brighter Polaris, it indicates the direction from south to north. If it is in the winter, because of the sunshine, the hard-to-melt parts of the snow always face the north. In addition there are temples, pagodas, and most of the general housing faces south, while the Islamic mosque door faces east. In addition, there are also discriminative directions such as the use of Polaris to determine the direction, the natural wind direction of each season, and the desert dune landform. The direction of the specific situation to determine the specific analysis, comprehensive judgments.
There are many methods and experiences in the direction of field discrimination. The commonly used methods are:
Compass (Northern Arrow):
A small compass with a clear scale can be prepared. Some mini compasses on the market are easy to confuse with their scales. It is better to use a liquid-filled blank. Be sure that you do not leak during purchase. bubble. In the specific use must ensure the level of use. The common models used by field military and geological teams are: 62, 65, and ZBZ-80. They are simple to use and easy to carry.
Watch judgment method:
The earth rotates 360 degrees in 24 hours, so 1 hour is 15 degrees, and the watch rotates 360 degrees in a week to 12 hours, which is 1 times faster than the sun, so that the watch and the sun can be used to roughly determine the bearing. At 6 o'clock in the morning, the sun is in the east, and the shadow is pointing to the west. The hour hand dial 6 points to the sun, and the dial 12 points to the west; if the dial is rotated 90 degrees, that is, 6 divided by 2 is 3, then 3 points to the sun, and 12 points North; Also at 12 noon, the sun is located in the south, 12 divided by 2 is 6, then 6 points to the sun, then 12 points to the north. According to this method to determine the direction of the shortcomings is best to consider the local time difference, so as to avoid deviations in the azimuth, but it may be used as a simple judgment of the position.
Plant discrimination method:
As the saying goes: "Everything grows depends on the sun." With this feature in mind, you can observe and judge the direction even on a cloudy day without the sun. Such as: large stones, the south of the trunk of the tree grows more vigorously, the grass in the south of the autumn also withered faster; the bark is generally smoother to the south, rougher to the north, and some trees have on the bark of the north Many cracks and flaws are particularly prominent in birch trees; pine gums and cedar trees have a lot of jelly on the south side of the tree trunk, and they tend to form larger blocks in the south; many fruit trees face southwards in autumn. There are more knots, especially apples, red dates, persimmons, and oranges. The fruit is also discolored toward the south when it matures; the moss on the stones is hi and damp, the north is prosperous, and the snow melts more. It is the one that melts southward first;
How to get out of trouble after losing the field in the wild
1. When you find yourself lost, look ahead. As the saying goes, “The station's high look is farâ€. This is especially true in the mountains. You should first climb up the ridge to observe it. You should usually walk toward a low-lying area so that you can easily find the water source. It is most safe to travel along the river and this is particularly important in the adventure of alpine forests. As the saying goes: "Water can send people home" is this truth. Because roads and settlements are usually built on the river. The ridges also have a certain guiding function. As long as you go along the ridge, you can usually reach a certain goal. In practical work, we have repeatedly warned tourists: "Leave the ridge without leaving the ditch," because in addition to the thorns in the ditch, there are extremely dangerous loose rolling stones.
2, in the vast desert and snow, due to single scenery, because the average person walking in the absence of reference will appear more than the right footsteps 0. 1-0. 4mm, which often do not know in the march, and finally caused Walking around the circle within 3-5 kilometers, it is easy to say: "Ghosts hit the wall." In this way, the “stacked reticle method†can be used in the above areas, ie, the three-point line can be used to maintain the linearity of the direction. You can make a mark for each section of the road (such as: put a stone, cut a tree branch, or mark a trunk)
3. The surface of the road often used by people is hard due to repeated trampling. There are road types. But not all the roads are taken by people. If the upper body often encounters rattan and the lower body has no such mess, then this road may be a way for the beasts to emerge. They must immediately give up and return.
4. When you come to the intersection, the roads are also confusing. At this time, you must clear the direction and then choose the road. If several roads have the same direction and you cannot judge, you may choose the middle road. It will not be too much.
Finally, we remind everyone that once such problems are encountered, first of all, we must be calm and have firm confidence. Second, we must use relevant knowledge to judge the direction and make decisions. If you can't get out, you can try to make a distress signal: You can fire the fire at a high place. It is better to smoke in the daytime, 6 times a minute. This is a common international distress signal. In short, as long as there is a strong belief, through hard work, we will certainly be able to get out of the predicament and enter the “dark and bright†situation.
