植树节是按照法律规定宣传保护树木，并动员群众积极参加以植树造林为活动内容的节日。中国的植树节定于每年3月12日，这一天是孙中山先生逝世纪念日。孙中山先生生前十分重视林业建设，1979年，全国人大常委会将3月12日定为中国植树节，以纪念孙中山先生，也是为了动员全国人民积极植树造林，绿化祖国，改善环境，造福子孙后代。植树节体现了中国人民对森林资源的重视和对生态环境保护的决心，是建设生态文明、美丽中国的重要载体。每年这一天，全国各地都会开展形式多样的植树活动，播撒绿色，播种希望。

中国古代就有植树的传统。《礼记》中记载"孟春之月，盛德在木"，意思是春季万物生长，正是植树的好时节。古代许多名人都提倡植树，如唐代诗人白居易曾说"手栽两松树，聊以当嘉宾"。中国近代植树节的设立与孙中山先生密切相关。孙中山先生是中国近代最早意识到森林价值和倡导植树造林的人。1915年，在孙中山先生的倡议下，当时的北洋政府规定每年清明节为植树节，后因清明节各地习俗不同，改为3月12日。1925年3月12日，孙中山先生在北京逝世。1928年，为纪念孙中山先生逝世三周年，国民政府举行了植树仪式。1979年2月，第五届全国人大常委会第六次会议根据国务院提议，决定每年3月12日为中国植树节，以鼓励全国各族人民植树造林，绿化祖国，改善环境，造福子孙后代。选择3月12日作为植树节，一是为了纪念孙中山先生，二是因为这个时节正值惊蛰之后、春分之前，全国大部分地区春回大地，正是植树的最佳时机。

Arbor Day is a festival designated by law to promote tree protection and mobilize the masses to actively participate in tree planting and afforestation activities. China's Arbor Day is set on March 12th every year, which is also the anniversary of Dr. Sun Yat-sen's death. Dr. Sun Yat-sen attached great importance to forestry construction during his lifetime. In 1979, the Standing Committee of the National People's Congress designated March 12th as China's Arbor Day to commemorate Dr. Sun Yat-sen and to mobilize the people of the country to actively plant trees, green the motherland, improve the environment, and benefit future generations. Arbor Day embodies the Chinese people's emphasis on forest resources and determination to protect the ecological environment. It is an important carrier for building ecological civilization and Beautiful China. Every year on this day, tree planting activities in various forms are carried out across the country, spreading green and sowing hope.

Ancient China had a tradition of tree planting. The "Book of Rites" records "In the first month of spring, great virtue is in wood," meaning that spring is when all things grow and is a good time for planting trees. Many famous people in ancient times advocated tree planting. For example, Tang Dynasty poet Bai Juyi said "I planted two pine trees by hand, treating them as honored guests." The establishment of modern China's Arbor Day is closely related to Dr. Sun Yat-sen. Dr. Sun Yat-sen was the first person in modern China to realize the value of forests and advocate tree planting and afforestation. In 1915, at Dr. Sun Yat-sen's initiative, the then Beiyang Government designated Qingming Festival as Arbor Day, but it was later changed to March 12th because Qingming customs varied in different regions. On March 12, 1925, Dr. Sun Yat-sen passed away in Beijing. In 1928, to commemorate the third anniversary of Dr. Sun Yat-sen's death, the Nationalist Government held a tree planting ceremony. In February 1979, the Sixth Session of the Standing Committee of the Fifth National People's Congress decided, based on a proposal from the State Council, that March 12th of each year would be China's Arbor Day, to encourage people of all ethnic groups across the country to plant trees, green the motherland, improve the environment, and benefit future generations. March 12th was chosen as Arbor Day for two reasons: first, to commemorate Dr. Sun Yat-sen, and second, because this time is after the Awakening of Insects and before the Spring Equinox, when spring returns to most parts of the country, making it the best time for tree planting.
