Forest survival composition

One day ten years later, an expedition and I came to a tropical forest in a foreign country, where the trees are interlaced and there are many traps everywhere. If we are not careful, we will be doomed. ...

When the sun was setting and red clouds filled the sky, I suddenly found no one around me. I was terrified and shouted the names of my teammates, but I got waves of ethereal echoes. I wanted to make a phone call, but I found there was no signal in the forest. I collapsed to the ground. The fact tells me an incredible news-I am isolated from the world! ! !

After a while, I got up. I have to go back alone. Now I only have a lighter, a big bottle of water and a self-defense gun. As night falls, I sing "Empty City Plan" in my stomach. First of all, I want to solve the food problem. It shouldn't be difficult to find some rabbits in the big forest. I groped my way forward step by step with a lighter and a gun. The forest in the dark looks darker. I hear a few gibbon screams from time to time. I was so nervous that I could hear my heartbeat and my palms were sweating a little.

Walking, I feel something stepped on. I looked down, my god! I can't help but gasp, a dog that has been gutted! ! There are wild animals nearby, I told myself. Suddenly, a cold air rushed to my spine, and my heart almost jumped into my throat. Suddenly, a voice and a small shadow passed by. My intuition tells me that dinner has been left behind. I gritted my teeth and fired a shot by feeling ... a sharp gunshot pierced the night sky. I subconsciously ran over and there was a rabbit lying there. I wiped the cold sweat from my head and carried the hare back.

Back to the original place, I took a bamboo stick, inserted the rabbit, peeled it, lit the leaves with a lighter, and while baking, I thought: I must go out tomorrow! After eating, I recovered a lot, so I packed my bags and watched the Big Dipper continue on the road in the moonlight, hoping to find an exit.

At midnight, everything was quiet. I don't know how long I've been gone. I'm thirsty. I can only have a sip of water. My vision has blurred. I have to sit down and have a rest. I sat down against the tree and felt something not far away (I believe my feeling). When I looked at it with a lighter, I almost didn't call out a pair of tigers sleeping soundly. This place is not suitable for staying long, and my physical strength has almost recovered. It gave a dull roar. "it's over." I thought, where is the whole person? After a while, I turned around and turned over. It was a false alarm. I felt a sort of surge of relief.

Time goes by, the dawn is coming, but the dawn of my victory has not yet appeared. I'm about to collapse. Just when the hope was dim, I saw a pair of ghostly green eyes, which are the unique signs of the Wolf clan. I really wanted to cry at that time. I really just escaped from the jaws of death and was caught by wolves. Seeing the fierce wolf approaching me, the instinct of survival drove me to turn around and run. (But it's no use, how can people run? ) I shot back as I ran. For some reason, the wolves retreated and I escaped.

I walked for most of the afternoon, and finally when the water was running out, the exit appeared! When the sun goes down, the afterglow of the setting sun fills the forest ... Responder: Chen Chenchen 51728 | VI | 2011-4-2818: 36.

Carry a hound, a lighter and a knife.

Determine the direction:

1, using the sun

In winter, the sunrise position is south-east and the sunset position is south-west; In summer, the sunrise position is north-east and the sunset position is north-west; Around the vernal equinox and autumnal equinox, the sunrise is due east and the sunset is due west.

As long as there is the sun, you can tell the direction with your watch. Read the time according to the 24-hour system, and divide the hour by 2 to get one hour. Put the watch horizontally on your hand or on the ground, so that the moment of the watch is aimed at the direction of the sun. At this time, the direction of 12 on the watch surface is north, and the direction of 6 o'clock is south.

Immediately, erect a pole on the ground. In the morning, the shadow points to the northwest, in the afternoon, the shadow points to the northeast, and the shortest shadow points to the north at noon.

Step 2 use stars

Aim for the North Star. First, find the spoon-shaped Big Dipper, and extend the interval between the two stars on the spoon C by five times. Then, you can find the Polaris on this straight line. The direction of Polaris is due north.

4. Use features to judge orientation.

Independent trees usually have lush foliage in the south, smooth bark in the north, sparse branches and rough bark. The south is generally thick with grass, while the north is wet and covered with moss.

For buildings and mounds, the snow in the north melts slowly, but in depressions such as potholes, the situation is just the opposite.

The doors and windows of large temples, pagodas and rural detached houses in northern China are mostly open to the south.

The northern edge of the clearing in the forest is covered with grass. The annual rings on the cross section of the stump are generally separated in the south and smaller in the north.

In the grassland and desert areas in northern China, many snow dragons and salons are often formed near the north wind and grassland. They have big heads and small tails, and their heads point northwest.

The doors of Mongolian yurts on the grassland are mostly facing south. The sparse side of leaves is south and the dense side is north.

The dense side of the tree stump is the north.

Put the pin in a puddle with grease, with the tip pointing north.

1. On the sunny side (i.e. facing south), a single tree is luxuriant in foliage, while on the shady side (i.e. facing north), the foliage is sparse.

2. In the dense forest, the south of the rock is dry, while the north of the rock is wet and covered with moss.

3. Peach trees and pine trees secrete gum mostly in the south.

4. Tree rings of stumps are sparse in the southern half and dense in the northern half.

The part of snow that is difficult to melt, such as ravines or rocks, is always in the north direction.

6. Ants' caves are mostly in the south of big trees, and the holes face south.

7. Some natural villages are generally concentrated on the south side of the mountain, and most of the gates face south. Generally, ancient temples, pagodas, ancestral halls and other buildings face south.

8. If you can see the stars in the sky at night, as long as you find the Big Dipper, you can find the bright Polaris along the extension line of the spoon handle, and the direction of Polaris is the true north direction.

Using the sun

On a clear day, according to the sunrise and sunset, you can easily know the east and the west, and you can judge the profile, but it can only be a rough estimate. There are the following methods to determine more accurately:

1, watch direction finding "hours are half of the sun, 12 refers to the north". Generally, you can quickly identify the direction between 9: 00 am and 4: 00 pm, and the direction you point to half the time is facing the sun, and 12 is the north. For example, in the afternoon 14:40, half is 7: 00. Or put a watch, put a stick in the center of the watch to turn the watch, so that the shadow of the stick coincides with the hour hand, and the bisector between the hour and 12 is the north. The earth rotates 360 degrees in 24 hours, so 1 hour is 15 degrees, while the watch rotates 360 degrees is 12 hours, which is 1 times faster than the sun, so that the position can be roughly determined by the watch and the sun. At 6 o'clock in the morning, the sun is in the east and the shadow points to the west. When the hour hand 6 of the dial points to the sun, 12 on the dial points to the west. If the dial is rotated 90 degrees, that is, 6 divided by 2 equals 3, then 3 points to the sun, and at this time 12 refers to the north; Similarly, at noon 12, the sun is in the south. Divide 12 by 2 to get 6,6 points for the sun and 12 points for the north. The disadvantage of this method is that it is best to consider the local time difference and avoid azimuth deviation, but it may be used as a simple judgment of approximate azimuth.

It must be pointed out that:

(1) When judging the direction, the watch should be flat;

(2) In the area between 20 30' south latitude, it is not suitable for use around noon, that is, every 15 plus 1 hour in the east and every 15 plus 1 hour in the west.

The direction of the sun shadow is sunny, and a wooden stick is erected on the ground. The shadow of the stick moves with the position of the sun. These shadows are the shortest at noon, the connecting line at the end is a straight line, and the vertical line of the straight line is the north-south direction.

Draw a series of concentric circles on a piece of 50×50cm drawing paper, with the radius of concentric circles increasing by 1cm, nail them horizontally on a flat plate, and vertically insert a thin steel needle or needle with a length of 12- 15cm on the center of the circle. When the position of the sun changes, the endpoint of the shadow always intersects with the concentric circles. Draw these points, then connect two straight lines on the same circle, and connect the midpoint of these straight lines with the center of the circle. This connecting line is the north-south direction line, and the direction of the arc top is the north.

3. Night Star

At night, you can judge the direction according to Polaris and Southern Cross.

1, Polaris is located in the northern sky, and its exposed altitude angle is equivalent to the local latitude. Based on this, you can find Polaris quickly. Usually according to the Big Dipper (Ursa Major) or the W Star (Fairy Queen).

The Big Dipper is seven bright stars, shaped like a spoon. The place where the two β -α directions of the spoon extend about 5 times is Polaris.

When you can't see the Big Dipper, you can look for the North Star according to the constellation W after Fairy.

Cassiopeia consists of five bright stars, shaped like a "W" letter, and the distance between the opening direction and the opening width of the letter is about twice that of Polaris.

2. Southern Cross

In the area south of 23 30' north latitude, the Southern Cross is sometimes seen at night. It consists of four bright stars in a cross shape. At the lower right, the length from γ to α of the four and a half times (no stars) connecting two stars is due south.

4, function and plant characteristics

Sometimes some ground objects and plant growth characteristics in the wild are good direction signs. Increasing this knowledge can help you quickly identify the direction.

1, function

Houses: Generally, the doors face south, and the doors and windows of large temples and pagodas in the north and rural independent houses face south. On the grassland, the doors of Mongolian yurts mostly face southeast.

Temples: usually open to the south, especially the main buildings in the temple group;

Remarkable features: Bryophytes, whose base is wet to the north, may grow low.

For buildings and mounds, the snow in the north melts slowly, but in depressions such as potholes, the situation is just the opposite. There are many northwest winds blowing in the grasslands and desert areas in northern China, and many snow dragons and salons often form near the grasslands. They have big heads and small tails, and their heads point northwest.

Plant growth characteristics

As the saying goes, "Everything grows on the sun". After mastering this characteristic, even on a cloudy day without the sun, you can judge the direction by observation. For example, the grass in the south of big stones and tree trunks grows vigorously, and the grass in the south withers faster in autumn; Bark is generally smooth in the south and rough in the north. There are many cracks and protrusions on the northern bark of some trees, which is especially obvious in birch. The gum resin from conifers and firs on the trunk is more in the south than in the north, which is easy to form a larger block; In autumn, many fruit trees bear more fruits facing south, especially apples, red dates, persimmons and oranges. The fruit changes color first when it is ripe. Moss growing on stones likes humidity, and the north is more prosperous; Most of the snow melts in the south first;

Generally, on the shady slope, that is, the northern slope, low ferns and vines are more developed than on the sunny slope. The northern edge of the clearing in the forest is dense with grass.

A plant has lush leaves on the sunny side, and moss may grow on the shady trunk in the north. Independent trees are usually lush in the south with smooth bark; The leaves in the north are sparse and the bark is rough. In the south, grass is usually lush, in the north, it is wet and covered with moss.

Many trees in northern China have clear annual rings on their trunks. The rings on the south side are sparse and those on the north side are dense. Generally speaking, the tree ring pattern on the cross section of the stump is separated in the south and smaller in the north.

If you get lost on a cloudy day, you can know your position by the growth of moss on trees or stones. As far as the trees in the northern hemisphere are concerned, the leafy side is the south. If you cut down a tree, the ring is wide and the moss is wet. Everyone has the instinct to survive, and it is king only in the most dangerous time! !
