Every year on March 12 is China's Arbor Day, which is a holiday set by some countries through legislation in order to stimulate people's feelings of love for forests and afforestation, to promote the greening of the country, and to protect the ecological environment on which human beings depend for their survival.
China's Arbor Day is set on which day
China's Arbor Day was set up by a forester's initiative in 1915, and the time was initially set at Qingming every year. After New China became a nation, it was decided that March 12 of each year would be China's Arbor Day.
The origin of Arbor Day
China's Arbor Day is March 12th. In ancient China, although there are persuade the people to plant trees, but by the state in the form of law explicitly stipulated the day of Arbor Day is a modern thing. 12 March this day the anniversary of the death of Dr. Sun Yat-sen. This day is designated as Arbor Day, firstly, from the consideration of the season of planting trees, and secondly, in order to commemorate the achievements of Dr. Sun Yat-sen's lifelong advocacy of tree planting.
In 1883, only 18 years old Sun Yat-sen, thousands of miles from the United States Honolulu to bring back seedlings planted by hand, in his careful cultivation finally came to fruition. Sun Yat-sen is also the earliest modern advocate of reforestation in China. He personally drafted the political document "on Li Hongzhang book", China wants to be strong, we must "urgently promote the agricultural science, the tree art". After the Xinhai Revolution, Dr. Sun proposed a plan for large-scale afforestation in northern and central China, and in 1924, he emphasized in a speech in Guangzhou that the fundamental way to prevent floods and droughts was to keep planting trees, and to create large-scale forests. In addition, in many of his writings and speeches, he repeatedly emphasized the dangers of deforestation and the importance of reforestation, and physically planted trees himself.
China's Tree Planting Day was initiated by foresters Han An and Ling Daoyang, and was initially set on April 5, the Qingming Festival, and changed to March 12 in 1928 to commemorate the third anniversary of Dr. Sun Yat-sen's death.
In the summer of 1981, Sichuan, Shaanxi and other places in the history of rare floods. 1981 December the Fifth National People's Congress of the fourth meeting considered and adopted the "on the implementation of compulsory tree-planting campaign for the whole people's resolution".
On March 12, 1990, the Ministry of Posts and Telecommunications issued a set of four stamps on "Greening the Motherland", the first of which was "Compulsory Tree Planting for All". The resolution points out that where conditions exist, the Chinese people over 11 years of age *** and citizens of the country, in addition to the elderly, sick and disabled, according to local conditions, each person is obliged to plant three to five trees per year, or to complete the corresponding amount of labor seedlings, care and other greening tasks.
Today's deterioration of the ecological environment, pollution increases, the transitional development of resources, if our homes are already full of holes, so the significance of Tree Planting Day is more and more important, the establishment of ecological civilization consciousness and concept, planting trees, repairing the ecology, increasing forest resources, building a beautiful China.
What is the significance of Arbor Day: regulating the climate, nourishing water, reducing pollution
The determination of March 12 as Arbor Day, in addition to commemorating Dr. Sun Yat-sen, but also because the date of Arbor Day just happens to be a good day suitable for planting trees and forests. Tree planting brings us a lot of benefits, not only can beautify our living environment, but also expand forest resources, prevent soil erosion, wind and sand, protect farmland, regulate climate, maintain ecological balance and promote economic development.
Tree planting is to protect the environment on which we depend, not only can green and beautify the home, but also can play a role in expanding forest resources, prevent soil erosion, protect farmland, regulate the climate, promote economic development, etc., is a benefit to the present generation, the benefit of future generations of the grand project. In order to protect forestry resources, beautify the environment and maintain ecological balance, many countries around the world have set up Tree Planting Day according to the actual situation of their countries. As people's awareness of environmental protection continues to grow, and actively participate in afforestation activities, our human environment will be continuously improved.
Tree planting can beautify the environment, improve air quality, but also improve the climate, the dense canopy can cover the sun's irradiation, will be about 20% of the heat reflected back to the sky, 60% -70% of the heat is absorbed by the canopy. In addition the maintenance of plant transpiration also requires the absorption of large amounts of heat. Because of the high humidity of the air in the woods, high heat capacity, and the wind is small, so the temperature change is relatively slow.
