The Origin and Significance of Arbor Day

The Origin and Significance of Arbor Day

The significance of planting trees is not that everyone should plant a tree on Arbor Day, but that we should pay more attention to greening and environmental protection through the arrival of voluntary tree planting again. The following is the origin and significance of Arbor Day that I organized. Welcome to refer to!

Origin and significance of Arbor Day 1 1. Origin of Arbor Day

March 12 every year is the Arbor Day in China. In fact, this day is the anniversary of Dr. Sun Yat-sen's death. To determine this day as Arbor Day, the first thing is to consider the planting season. The second is to commemorate the achievements of Dr. Sun Yat-sen in advocating afforestation all his life.

Dr. Sun Yat-sen loved planting trees since he was a child, and there is still a 100-year-old Honolulu sour bean tree growing in his former residence. This is 1883. Sun Yat-sen, who was only 18 years old, brought back saplings from Honolulu, USA and planted them himself. Under his careful training, he finally became a useful person. Sun Yat-sen was also the first person in modern China who strongly advocated afforestation.

Second, the benefits of planting trees.

1. Trees can regulate climate and keep ecological balance. Through photosynthesis, trees inhale carbon dioxide and exhale oxygen, making the air clean and fresh. One acre of forest releases enough oxygen for 65 people to breathe for a lifetime.

2. Trees can prevent wind and fix sand, keep water and soil, and absorb all kinds of dust. An acre of forest can absorb 20-60 tons of dust a year.

3. Woods can reduce noise pollution. A 40-meter-wide forest belt can reduce noise10-15db. Noise pollution has caused great harm to human life, study, work and rest, and can be said to be people's "enemy". Therefore, we should pay more attention to afforestation. Noise can also lead to hearing loss, deafness and stupidity, as well as heart, blood pressure and nerve abnormalities in long-term life. Even, it can make people die under long-term noise.

The secretions of trees can kill bacteria. There are 34,000 bacteria per cubic meter of air in the open space, and only 300-400 bacteria in the forest. Planting trees is the obligation of every citizen, and the state has designated March 12 as Arbor Day. Planting trees is of great benefit to our study, work and life.

5. Trees can lower the temperature and increase the humidity. At 30 degrees, the temperature can be reduced to about 20 degrees.

Three. Arbor day proposal

1, which does not damage greening, including: not picking flowers, not trampling on greening, not crossing open lawns, not playing in flower beds and other green spaces, and staying away from flowers and trees when playing games. Special reminder: students are not allowed to damage the flowers and trees in the school. Once found, it will be severely criticized. )

2. Participate in greening activities, do a good job in cleaning the school green space, and discourage uncivilized behavior in time.

3. Make your home a green home. Choose some plants suitable for growing at home and plant them on balconies and rooms. (These plants include: sunflower, rose, safflower, cactus, crab claw orchid and so on. Are all plants with high survival rate. )

4. Plant a sapling near your home and let the sapling grow with you.

We advocate starting from ourselves and starting from the side. Let's sow green and spread civilization. We believe that with moral sunshine, green trees will be evergreen. Let's work together to make our sky bluer, our land greener and our water cleaner!

The origin and significance of Arbor Day 2: As we all know, the earth is being desertified, and the area covered by desert is increasing year by year-but we seem to feel that these are still far away from us, but there are a group of people around us: they sow green for this land in obscurity, some of them are called "heroes", some are called "contemporary fools", and some are even foreign friends ... They tell us with practical actions that afforestation is.

The significance of Arbor Day is not that everyone should plant a tree on Arbor Day, but that through the coming of Arbor Day again, we all pay more attention to greening and environmental protection.

First of all, forests can balance the carbon dioxide of the earth. Forests are the main consumers of carbon dioxide. Every hectare of forest produces 10 tons of dry matter, which will absorb 16 tons of carbon dioxide and release 12 tons of oxygen, making the forest a huge oxygen storage. So afforestation has become the main way to slow down the greenhouse effect.

Second, forests can prevent wind and fix sand. Forests can reduce wind erosion intensity by reducing wind speed and changing wind direction; The strong roots of trees, especially shrubs, can fix soil particles. Practice has proved that building windbreaks, combined with agricultural and water conservancy measures, can achieve good windbreak and sand fixation effects.

Third, forests can keep water and soil. Forests can regulate runoff and water quantity in dry season, maintain soil and water, reduce river sediment content and alleviate flood disasters. The observation shows that the litter layer with the thickness of 1 cm can reduce the surface runoff to 1/4 of the bare land, and the sediment amount can be reduced by 94%. The bare soil loss caused by rainfall is more than 1000 times that of forest land, but the soil consolidation ability of the combination of trees, shrubs and grass is more than1000 times that of pure grass. It is estimated that China's forests reduce the total soil erosion by 24.6 billion cubic meters every year, reduce the soil organic matter loss by 384 million tons, and the soil protection value reaches more than 260 billion yuan. In addition, forests have a fundamental mitigation effect on preventing riverbed rise, floods and droughts.

Fourth, forests can conserve water. Forest is a natural "green reservoir", which can promote the normal circulation of sky water, surface water and groundwater. When it rains, more than 20% of the rainfall is intercepted by tree crowns and branches and leaves, and 5% ~ 10% is intercepted and absorbed by ground leaves and weeds. Soil with granular structure in forest can quickly convert surface water into groundwater. According to incomplete estimates, the annual water conservation capacity of forests in China is 347.3 billion tons, equivalent to 75% of the total storage capacity, and the annual water conservation value is more than 250 billion yuan.

Fifth, forests can protect biodiversity. Forest is the "home of species" and the biggest treasure house of biodiversity and biological gene resources. More than 50% species in the world inhabit various forests, mainly natural forests.

The origin and significance of Arbor Day 3 Arbor Day is a statutory holiday in China, which was put forward to enhance public awareness of environmental protection. For the arrival of this day, many students, workers and white-collar workers will organize to participate in tree planting activities, popularize greening and get the effect of afforestation, which is conducive to the sustainable development of natural resources in China. Let's listen to the introduction of Taikang Life Insurance Company!

For many primary school students, they will know about Arbor Day when they first study, and gradually understand that they can participate in tree planting activities on this day. There are also many social people who organize activities collectively and make great contributions to the greening of the country. Of course, for the meaning of planting trees, but also for the benefit of our future generations. After all, it is necessary to plant trees from the perspective of China's frontiers, especially Xinjiang, Tibet and Inner Mongolia. The best improvement strategy of land desertification is to achieve the purpose of greening by planting trees.

The existence of Arbor Day is also a symbolic festival in China. Held every March 12. In many primary schools, junior high schools, senior high schools and universities, the annual Arbor Day will arrange activities related to greening and tree planting, and sometimes education and publicity will be carried out. This awareness has enhanced people's awareness of self-protection, especially for some young people of the new generation. Their existence is very valuable. Especially in recent years, the smog weather, air pollution and poor air quality can be improved to some extent if more trees are planted.

The existence of forest is of great significance to a country and society, not only the existence of natural resources, but also the improvement and guarantee of a country's ecological environment. For personal health, a good ecological environment can ensure people's health and enjoy a better life. This is more effective than buying some medical insurance and critical illness insurance. Of course, the existence of Arbor Day is also meaningful for disease prevention, but these two guarantees have different directions and different values, and they can also play a practical role in our lives, so greening and afforestation are very serious for every generation of children and grandchildren.

The origin and significance of Arbor Day is beneficial to human beings, which represents the prosperity of a country and the development of a country's ecological civilization.

The Origin and Significance of Arbor Day Chapter IV The Origin of Arbor Day

In ancient China, there was a tradition of inserting willows and planting trees in Tomb-Sweeping Day. Arbor Day Modern Arbor Day was first initiated by Nebraska, USA. 19th century ago, Nebraska was a bare wasteland, with few trees, dry land, strong winds and yellow sand all over the sky, and people suffered greatly. 1872, Julius Sterling Moreton, a famous American agronomist, proposed to stipulate Arbor Day in Nebraska to mobilize people to plant trees in a planned way.

At that time, the state agricultural bureau adopted this proposal through a resolution, and the governor personally stipulated that the third Wednesday of April would be Arbor Day every year. After making this decision, millions of trees were planted that year. In the following 16 years, 600 million trees were planted one after another, eventually turning the 654.38+10,000 hectares of wilderness in Nebraska into dense forests. In recognition of Moreton's achievements, 1885, the state legislature officially designated April 22nd, Mr. Moreton's birthday, as the annual Arbor Day, with one day off.

In the United States, Arbor Day is a national holiday, and there is no unified national date. But every April and May, every state in the United States organizes Arbor Day activities. For example, Rhode Island stipulates that the second Friday in May is Arbor Day, which is a day off. Other states have fixed dates, and some temporarily decide the date of Arbor Day by the governor or other state government departments every year. Whenever Arbor Day comes, people from all walks of life, mainly students, form a mighty army of tree planting and devote themselves to tree planting activities.

In America today, there are rows of trees and avenues. According to statistics. About13 of the United States is covered with forest trees, which is closely related to Arbor Day.

The Origin of Arbor Day in China

Shortly after the establishment of the Nanjing government of the Republic of China with Sun Yat-sen as the interim president, the Ministry of Agriculture and Forestry was established in May 19 12, and the Mountain Forest Department was in charge of the State Forestry Administration. 19141kloc-0/In June, the first forestry law in China's modern history was promulgated.

19 15 In July, at the initiative of Sun Yat-sen, the then Beiyang government officially ordered that Tomb-Sweeping Day be designated as Arbor Day every year, and tree species should be selected. Governments, institutions and schools at all levels in the country should attend as scheduled, hold Arbor Day ceremonies and engage in tree planting activities. After it was approved on July 2 1 day of that year, the whole country was ordered to comply with it as scheduled. Since then, Arbor Day has been held in China.

On March 1925, Dr. Sun Yat-sen passed away. 1928 xx government held a tree planting ceremony to commemorate the third anniversary of Sun Yat-sen's death. In memory of Dr. Sun Yat-sen, March 12 is designated as Arbor Day every year.

On February 1979, after the founding of People's Republic of China (PRC), the 6th meeting of the 5th the NPC Standing Committee, on the proposal of the State Council, formally passed a resolution to designate March 12 every year as Arbor Day. The significance of this resolution lies in mobilizing the people of all ethnic groups in China to actively plant trees and speeding up the greening of the motherland and various forestry construction. China designated the date of Sun Yat-sen's death as Arbor Day, also to commemorate Sun Yat-sen's great achievements, symbolizing that his unfinished wish will be realized in new China.

The significance of Arbor Day

Control soil erosion, prevent wind and fix sand;

Increase the water storage capacity of soil, greatly improve the ecological environment and reduce the loss of flood disaster;

Automatic constant temperature: the temperature in the cool place in summer is about 10 degrees lower than that in the open place, and it is 2-3 degrees higher in winter.

Natural dust collector: there are many fine hairs and mucus on the leaves, which can absorb harmful particles such as carbon and sulfide in the smoke and dust, as well as harmful substances such as germs and viruses, and can greatly reduce and reduce the dust in the air. A hectare of lawn can absorb more than 30 tons of smoke and dust every year. Therefore, people call green plants "natural vacuum cleaners".

Oxygen factory: leaves can absorb carbon dioxide from sunlight and make oxygen needed by human body. It is measured that one hectare of broad-leaved forest absorbs about one ton of carbon dioxide and releases 700 kilograms of oxygen every day. Therefore, people call green plants "oxygen factories".

Sterilization station: Pine trees, camphor trees, elms and other trees can secrete fungicides to kill mycobacterium tuberculosis, diphtheria and other germs.

Natural silencer: Greening can absorb sound waves and reduce noise.
