More green leaves and more warmth, content introduction of Arbor Day themed class meeting PPT:
1. The history of Arbor Day
In ancient my country, there was a tradition of planting willows and trees during the Qingming Festival.
The modern Arbor Day was first initiated by the state of Nebraska in the United States. Before the 19th century, Nebraska was a bare wilderness with few trees, dry land, strong winds, and yellow sand in the sky, and the people suffered deeply from it. In 1872, the famous American agriculturist Julius Sterling Moulton proposed to establish Arbor Day in Nebraska to mobilize people to plant trees in a planned way.
At that time, the state Agriculture Bureau passed a resolution to adopt this proposal, and the governor personally designated the third Wednesday in April as Arbor Day from now on. After this decision was made, millions of trees were planted that year. In the next 16 years, another 600 million trees were planted, finally turning 100,000 hectares of wilderness in Nebraska into a dense forest. In recognition of Moulton's achievements, in 1885 the state Legislature officially designated April 22, Mr. Moulton's birthday, as Arbor Day each year, with a day off.
The history of afforestation in China can be traced back to 2,600 years ago. In ancient my country, there was a tradition of planting willows and trees during the Qingming Festival. However, afforestation and forestry development truly became strategic tasks for national construction after the founding of the People's Republic of China, and becoming a legal citizen began at the beginning of reform and opening up. Sun Yat-sen worked hard to promote tree planting when he took office. In November 1914, the Republic of China promulgated the first "Forest Law" in my country's modern history. In July 1915, the government stipulated that the annual "Qingming Festival" should be designated as Arbor Day. On March 12, 1925, Dr. Sun Yat-sen passed away. In order to commemorate the founding father of the country, Dr. Sun Yat-sen, the National Government designated March 12 every year as "Arbor Day".
2. The origin of Arbor Day
Shortly after the founding of the Nanjing government of the Republic of China, where Sun Yat-sen served as interim president, at Sun Yat-sen's initiative, the Qingming Festival was designated as Arbor Day every year. Governments, agencies and schools at all levels across the country participated as scheduled, held Arbor Day ceremonies and engaged in tree planting. Since then, our country has had Arbor Day.
On March 12, 1925, Dr. Sun Yat-sen passed away. In 1928, to commemorate the third anniversary of Sun Yat-sen's death, the Nationalist Government held a tree-planting ceremony. In order to commemorate Dr. Sun Yat-sen, March 12th will be designated as Arbor Day every year. In February 1979, after the founding of the People's Republic of China, a resolution was officially adopted to designate March 12th as Arbor Day. The significance of this resolution is to mobilize people of all ethnic groups across the country to actively plant trees and accelerate the pace of greening the motherland and various forestry constructions.
Arbor Day in our country has been revised three times due to the evolution of the times.
After the Revolution of 1911, in the 4th year of the Republic of China (1915), Zhou Ziqi, Director-General of the Ministry of Agriculture and Commerce, proposed to the quasi-president that Qingming Festival be designated as Arbor Day every year.
Dr. Sun Yat-sen passed away on March 12, 1925. In order to commemorate this great man, the Kuomintang government changed Arbor Day to March 12 every year in 1930.
After the founding of the People's Republic of China, in 1979, at the suggestion of Deng Xiaoping, the sixth meeting of the Standing Committee of the Fifth National People's Congress decided that March 12 every year would be my country's Arbor Day.
In 1956, Mao Zedong issued a call to "green the motherland" and "realize the gardening of the earth." China has launched a “12-year greening campaign” with the goal of “basically eliminating wasteland and barren mountains within 12 years, and planting green trees beside all houses, villages, roadsides, watersides, and barren lands and mountains, that is, wherever possible.” We need to plant trees according to specifications and practice greening.”
In 1979, at the suggestion of Deng Xiaoping, the sixth meeting of the Standing Committee of the Fifth National People's Congress decided that March 12 every year would be my country's Arbor Day.
On December 13, 1981, the Fourth Session of the Fifth National People's Congress discussed and adopted the "Resolution on Launching a National Voluntary Tree Planting Movement." Since then, the national compulsory tree planting movement has been implemented as a law across the country.
3. The meaning of festival emblem
1. The shape of a tree means that all people are obliged to plant 3 to 5 trees, and everyone takes action to green the land of the motherland.
2. "Chinese Arbor Day" and "3.12" represent the perseverance and determination to transform nature and benefit mankind by planting trees every year.
3. The five trees can be understood as "forest", extending from them to connect the outer circle, showing the greening of the motherland and realizing a virtuous cycle of the natural ecological system with forests as the main body.
4. The significance of Arbor Day
Urban shelterbelts have the effect of slowing down wind speed, and their effective range is within 40 times the tree height. The best effect is within the range of 10 to 20 times, which can reduce wind speed by 50%.
In farmland forest nets, wind speed can usually be slowed down by 30% to 40%, relative humidity increased by 5% to 15%, and soil moisture content increased by 10% to 20%. According to measurements, the forest canopy can intercept about 20% of precipitation.
The impact of raindrops is greatly weakened.
As long as there is 1 cm thick litter on the surface, surface runoff can be reduced to less than 1/4 of bare land, and sediment can be reduced to less than 7% of bare land.
One hectare of woodland can store at least 3,000 cubic meters more water than bare land. The water storage capacity of 10,000 acres of forest is equivalent to a reservoir with a storage capacity of 1 million cubic meters. Building such a
A reservoir requires an investment of more than 10 million yuan.

6. Arbor Day and Sun Yat-sen
March 12 is the anniversary of the death of Dr. Sun Yat-sen. Mr. Zhongshan attached great importance to forestry construction during his lifetime. Shortly after the Nanjing government of the Republic of China, in which he served as interim president, was established, the Ministry of Agriculture and Forestry was established in May 1912, with the Forestry Department under it to be in charge of national forestry administrative affairs. In November 1914, the first "Forest Law" in my country's modern history was promulgated. In July 1915, the government stipulated that the annual "Qingming Festival" should be designated as Arbor Day. Later, because the Tomb-Sweeping Day was too late for the tree planting season in southern my country, and in order to commemorate Dr. Sun Yat-sen, the National Government decided to designate March 12, Sun Yat-sen's death day, as Arbor Day.
