The origin of Arbor Day:

March 12th every year is Arbor Day in our country. In fact, this day is the anniversary of the death of Dr. Sun Yat-sen. This day is designated as Arbor Day, firstly, considering the tree planting season; secondly, to commemorate Dr. Sun Yat-sen’s achievements in advocating afforestation throughout his life.

Sun Yat-sen was the first person in modern Chinese history to realize the importance of forests and advocate afforestation. The political document "Li Hongzhang Shu" drafted by him personally stated that if China wants to be strong, it must "rapidly develop agriculture and pay attention to arboriculture."

After the Revolution of 1911, Mr. Sun Yat-sen proposed a large-scale afforestation plan in northern and central China. In 1924, he emphasized in a speech in Guangzhou: The fundamental way for us to prevent floods and droughts is to continue to plant trees, and to build large-scale forests. In addition, he repeatedly emphasized the dangers of deforestation and the importance of afforestation in many books and speeches, and practiced it by planting trees himself.

The ecological significance of Arbor Day

Trees are very important to the earth. They not only purify the air and prevent soil erosion, but also provide us with a large amount of wood for our use. It has great ecological significance.

Some foreign scholars have calculated the ecological value of trees: a 50-year-old tree produces oxygen worth about US$31,200; absorbing toxic gases and preventing air pollution is worth about US$62,500; increasing soil Fertility is worth approximately $31,200; water conservation is worth $37,500; providing breeding grounds for birds and other animals is worth $31,250; and protein production is worth $2,500. Excluding the value of flowers, fruits and wood, the total value is approximately US$196,000.

Regardless of whether this calculation is accurate, in terms of the practical value of trees, it is indeed obvious. One tree can produce 200 kilograms of pulp, and if this pulp is to be produced into toilet paper, it will require at least 750 rolls of toilet paper weighing 100 grams.

In the city, a tree can store the pollutants emitted by a car traveling 16 kilometers a year. Many trees can absorb harmful gases. For example, one hectare of cedar forest can absorb 60 kilograms of sulfur dioxide per day. Others such as ailanthus, oleander, ginkgo, and sycamore have the function of absorbing sulfur dioxide. When the urban green area reaches more than 50%, pollutants in the atmosphere can be effectively controlled. Urban forests can increase air humidity. An adult tree can evaporate 400 kilograms of water a day, so the air humidity in the forest increases significantly. It is calculated that for every 1% increase in urban green space, local summer temperatures can drop by 0.1 degrees Celsius. Urban forest belts and hedges can reduce noise. A 30-meter-wide forest belt can reduce noise by 6 to 8 decibels.

There are 3.5 bacteria per cubic meter of atmosphere in forested areas, and the number can reach 34,000 in densely populated cities lacking greenery. Urban streets with trees contain about 80% less pathogenic bacteria in the atmosphere than urban streets without trees. 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, greatly weakening the impact of raindrops; as long as there are 1 cm thick litter on the surface, the surface runoff can be reduced to less than 1/4 of bare land, and the sediment can be reduced to Bare land is less than 7%.

One hectare of forest land 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, and building such a reservoir requires an investment of more than 10 million yuan. Some experts predict that if forests are lost on the earth, about 4.5 million biological species will cease to exist, and 90% of the fresh water on land will flow into the sea in vain, and humans will face serious water shortages. The loss of forests has increased wind speed by 60% to 80% in many areas, and hundreds of millions of people have died due to wind disasters. ;
