83 4 meters China s tallest tree and other personal photos released, what is the relationship betw

The older the tree, the higher it grows, of course, this depends on the species of the tree, not all trees are like this.

The older the tree, the taller it becomes. The threads of the tree can represent the age of the tree, and the height of the tree is directly proportional to the age of the tree.

The height of the tree has a lot to do with the age of the tree, a healthy tree, only when it grows strongly, can it grow tall and strong, and the older it is, the higher it will grow.

This is the tallest tree in Chinese history, and more than 50 species of higher plants have been found on this tree, including climbing plants, epiphytes, parasitic plants, etc., creating a new climbing and collection record for giant trees in China.

The scientific expedition team conducted a systematic investigation on the distribution pattern, community structure and species composition of the primeval forest vegetation in the giant tree community and the surrounding areas, and found 2 new genera and 2 new species in China, and also collected more than 200 specimens and 50 seeds and living materials.

At present, all the acquired materials are preserved in the National Herbarium of China and the Chenshan Center of the National Important Wild Plant Germplasm Resources Repository.

First, the significance of measuring tall trees:

Zhong Xin of the scientific expedition team said that this scientific expedition needs to collect materials of different heights, including the leaves of this giant tree of different heights, as well as other epiphytes, parasitic plants and other plant materials.

It is of invaluable value for us to study the evolution of biomes and ecological adaptation in a region.

From a scientific point of view, finding the highest number of organisms in nature can improve the country's understanding of local ecosystems.

By looking for regional trees, we can promote the process of natural ecological protection in the region, and also raise people's attention, so as to promote the construction of a national park in Medog and the entire lower Brahmaputra region.

Second, my opinion on this matter.

Measuring tall trees requires the use of the latest technology, backpack lidar, this tool sounds very mysterious, in fact, the working principle is very simple, is to use a laser to determine the distance between two points, the distance data between the earth and the moon is also measured by laser, this technical practice is very important, only through practice, can strengthen the accuracy of measurement, in order to find more unknown.

Human beings and nature are both members of the earth, and human beings need to protect our common home in order to get more and more "noble trees".

This is the record for the tallest tree in China, and the Yunnan Huangguo fir reaches a height of meters, which is equivalent to the height of a 28-story building. This record shows the magnificence of the natural world and can also give everyone an idea of the significance of protecting natural ecology.

Chinese giant trees, Yunnan Huangguo fir and other body photos. ** "Wild China" Studio The Chinese giant tree expedition team recently released the exact height of the "tallest tree in China", Yunnan Huangguo fir. The tree is meters tall and about 28 stories tall.

The first point is that this is a very powerful record, and it also records how good our Chinese trees are, how tall the Chinese trees are, and the second point is to be able to understand the growth laws of trees.

Some of the main methods used are the direct tree climbing method, which is to manually climb to the top of the giant tree, determine the highest treetop end, and then measure it by lowering a metal tape measure.

It is understood that this scientific expedition used the "gold standard" of international measurement of giant trees - direct tree climbing method, that is, manually climb to the top of the giant tree, determine the highest treetops, and then lower the metal tape measure from the treetops to the ground for measurement.

Its height is artificially measured and is very standard, and this tree is Yunnan Huangguo fir.

You need to have enough nutrition, a stable environment, and no human destruction.

It has to be a very humid environment, and the air is also very humid, the ice cream also has very good nutrition, the soil is very full, and the light environment is better.

Remember that some of the conditions needed for growth are the right temperature, the right ecological environment, and the sunshine time, and these are also very helpful for the growth of the technology.

As we all know, when judging a person's age, you only need to take out your ID card and calculate it according to the above year of birth, but the age of an ancient tree cannot be measured by year, but by the development of the ancient tree and the growth ring. Generally speaking, the deeper the rings and the more laps, the older the number of strands, and each lap has a corresponding numerical representation. It can also be analyzed through scientific methods, that is, the use of scanners to understand the diameter of the ancient tree, including other aspects of knowledge, so as to calculate the age of the ancient tree.

In addition, it is also possible to use the needle tester method, that is, the needle is placed into the body of the tree, so that the growth waveform of the tree can be displayed on the machine, and the true age of the tree can be estimated through the waveform. CT scanning can also be used to determine the age of trees by scanning images. In the final analysis, the main purpose of these methods is to pass through the growth rings of ancient trees, but ancient trees are hundreds of years old, and it is impossible to cut off ancient trees in order to measure their age.

Secondly, it can also be determined by carbon-14 method, which sounds more advanced and more complicated to implement, and must be identified by professional personnel. It is also possible to estimate the true age of the old tree by talking to the old people in the village, but no matter which way the age is estimated, it is called an estimated age. It is still very difficult and cumbersome to obtain the true age of an ancient tree, and there is no technology on the market that can do this.

However, it is not possible to destroy an ancient tree for the purpose of measuring it, then this violates the artificial achievements of nature and affects the survival of an ancient tree. It is important to know that ancient trees can survive for a very long time, and try to let ancient trees die freely, even if ancient trees have a greater role in promoting geography and meteorology, but we have never seen these scientists openly release the phenomenon of ancient trees.

When the age of an ancient tree is measured, it is generally measured by a needle measuring instrument, and when measuring the tree, the waveform of the growth status of the ancient tree is output with special impedance to define the growth rings of the tree, or by CT scanning method.

The trunk analysis data of the same tree species in the local forest resource inventory (this climate zone) or the trunk analysis of logs of the same tree species in the lumber yard were used to obtain the growth ring and diameter data, and the regression model of the growth ring and diameter was established to calculate and estimate the age of ancient trees.

The age can be calculated by the rings on the top of the tree, and the more rings, the older the number.

It can be seen through the rings of trees, and one circle of the rings is a year.

Recently, Yunnan wild yew, known as "China's tallest tree", was officially listed as a national key protected wild plant, and at present, the plant is being comprehensively protected in Jinning District, Kunming City, Yunnan Province. So how tall is this tree? Why measure its height?

Yew is an ancient relict tree species that is widely distributed worldwideIt is recognized as the tallest higher plant in the world, and the tree is up to 60 meters high.

Yew is a leguminous plant and is the oldest natural anti-cancer plant in the world, with the highest natural biological activity in biochemical components such as paclitaxel, taxic acid, and natural paclitaxel. This is because its roots and leaves contain paclitaxel, and they have a very good effect on cancer, which can be said to be an all-natural product. Yew, commonly known as yew rice, yew, fir wood, etc.

It is a national first-class protected plant, and there are only more than 2,000 plants left in the world, most of which grow in Yunnan, China. Due to the low yield and high value of yew, it has also been overexploited in these areas for a long time, resulting in a decline in the natural population, and it has become a major endangered species among rare and endangered plants in China.

Yew seeds are edible and are recognized as excellent anti-cancer plants in the world. Yew can extract paclitaxel, which has anti-tumor, anti-radiation and other functions, and yew wood is rich in natural anti-cancer substances paclitaxel and filine, which can effectively prevent breast cancer and stomach cancer. Since yew cannot synthesize seeds on its own, it needs to be cultivated artificially.

Therefore, we need to measure its height, which is also to better protect the yew. This requires us to make the necessary preparations to ensure that the measurement results are accurate when we measure its height.

Since yew grows quickly and is usually grown at higher altitudes, it is important to pay attention to the accuracy of the altitude when taking measurements. Therefore, when measuring, the canopy, trunk diameter, the central part of the canopy and the cross-section of the trunk are first measured, and then the total height is calculated.

It is said that the height of the Liao tree was measured using the gold standard method, and the tree was meters.

The tree is very tall and can be measured with *** or infrared light, and the height of the tree is very accurate.

In my personal opinion, there are three conditions for a giant tree to grow. First, there is plenty of room to grow, allowing giant trees to grow freely; second, there are enough nutrients, including soil, water, and various minerals needed for growth; Thirdly, do not be disturbed by people, only in inaccessible areas, can trees continue to grow and not be destroyed by human felling.

The fact that the giant tree can be found by us means that it has "stood out from the crowd" and has become the most dazzling existence in the forest. The tallest tree in our country, reaching a height of meters, grows in inaccessible areas. The fact that these giant trees can grow has a lot to do with the suitability of the place where they grow, and many giant trees in the world also grow in uninhabited areas.

Therefore, for a giant tree to grow smoothly, the following two conditions are indispensable.

Giant trees are usually found in the wild environment, and it is difficult for them to grow into giant trees under human care. Just like the flowers in the greenhouse, if you are cared for all the time, your vitality will become fragile. It takes hundreds of years for each giant tree to grow, and some giant trees even go through thousands of years.

Their ability to thrive and be admired is related to the abundance of nutrients and space in the place where they grow. With a suitable growing environment, the trees will grow to the fullest, and if there is no space constraint, the trees will continue to grow taller.

The fact that giant trees can grow is not only a miracle of nature, but also a "mercy" of human beings. Since ancient times, people have had the habit of cutting trees, and tall and stout trees are preferred in the process of logging. In the era of no world record, I think that many towering trees did not fall in the cruel competition of nature, but fell in human felling.

Towering trees grow because they are far away from humans and are not disturbed by humans. Such a quiet growth environment gives them enough space and time to grow, so that we can only look up to them today and admire their tenacious vitality.

All giant trees grow from small saplings, and the growth of giant trees is not a day's work. Today's giant trees were also small saplings in the past; A small sapling of today may grow into a giant tree of tomorrow.

It needs to have a very good ecological environment, the local sunlight is relatively sufficient, the water replenishment is also abundant, it will not be cut down by man, and the surrounding environment is better.

Some of the conditions needed for the growth of these trees are fertilizer, and the sunlight hours contain some water that is needed, and these can help a tree grow normally.

China's tallest tree meter, is found in China's Yunnan Huangguo fir tree, this tree is equivalent to 28 stories high, its tree height has been revised is, in the previous measurement data, this number is 72 meters high, later in the process of revision, the tree continues to grow taller, and now it has reached the meter, perhaps it is now the continuous development of science and technology, people use lidar technology to accurately measure her, and also estimated his age, That's about 400 years old.

The discovery of this tree, and for the successful identification, investigation and protection of the important significance, the height of this tree is equivalent to 28 floors of false accusations in the extreme environment of the wild, it is extremely rare to grow so high, in the plains can be said to be such a tall tree, and the harsh changes in the environment do not allow the number to grow so high, only in high altitude areas can grow freely, and then these trees basically grow in a very special environment, Maybe these environments are very harsh, maybe the surrounding areas are inaccessible, but these environments are more suitable for the growth of trees.

In addition, in the area where the trees grow, his vegetation is also very rich, it can be said that the green area of the forest is very high, his terrain is also very complex, there are also a lot of tall trees and vegetation around, it can be said that it is suitable for dense rivers and a lot of rain. And social science calculations are estimated to be about 400 years old, but it is in the middle of life expectancy, that is to say, as long as the environment is normal, he is still relatively strong, and is in a stage of healthy development, as long as human beings do not destroy the environment, normal observation, measurement of it can be. These trees grow in the primeval forest, large trees are difficult to be found by humans, the mountains here are crisscrossed, and the altitude is relatively large, and there are fewer humans to enter, so they are too remote, but more suitable for the survival of trees.
