The grass and trees are spreading, and the spring mountain is expected. In March, China ushered in a good season for afforestation. By the Yongding River, spring is getting stronger and stronger. "Planting trees is not only planting green seedlings, but also the bright future of the motherland." "We should put the protection of the ecological environment in a more prominent position, protect the ecological environment as we protect our eyes, and treat the ecological environment as we treat life". The metaphor of "eyes" and "life" shows the general secretary's deep understanding of correctly handling the relationship between economic development and ecological and environmental protection in the new era. For a long time, especially since the industrial revolution, mankind has carried out unprecedented transformation of nature. With the rapid development of productivity, great changes have taken place in the natural ecosystem, such as the disappearance of forests, wetland degradation, soil erosion, drought and water shortage, frequent floods, global warming and other serious ecological crises. China is one of the countries with the most serious land and ecological security problems such as soil erosion, land desertification, rocky desertification and salinization in the world. Monitoring shows that in 2009, China's desertification land area accounted for 18.03% of the land area; The area of soil erosion accounts for 30% of the land area. Coming from the Loess Plateau, he has a deep memory of the harm of soil erosion; During his work in Fujian, he went to Changting for investigation five times to promote the control of soil and water loss in Changting. He once said sadly that the Hexi Corridor and the Loess Plateau had abundant water and lush grass. Due to deforestation and deforestation, the ecological environment was seriously damaged and the economic decline was exacerbated. "On the whole, China is still a country short of forests, less green and fragile ecology. Afforestation and improving ecology have a long way to go." Forest is the main body of terrestrial ecology and the foundation of human survival. "Our predecessors planted trees and our descendants enjoyed the cool. Our generation is to use their own efforts to benefit future generations"; "We should adhere to the national mobilization and the whole people to start afforestation, and strive to turn the construction of a beautiful China into people's conscious action"; "We should innovate the form of voluntary tree planting, make it easier for the people to participate in land greening, provide more high-quality ecological products for the people, and let the people share the achievements of ecological civilization" Saihanba, the "green pearl" in northern Hebei, was a vast wasteland where birds did not live and yellow sand covered the sky half a century ago. Three generations of people in Saihanba forest farm have insisted on afforestation for many years and irrigated millions of mu of artificial forest sea with sweat, which has played an important role in wind prevention, sand fixation and water conservation in Beijing, Tianjin and Hebei. Four years later, the general secretary came to the moon mountain of Saihanba mechanical forest farm and went deep into the boundless green forest to visit the forest rangers. "We build this forest and its ecological barrier role should be played forever". More than 1700 kilometers west of Saihanba, at the foot of Qilian Mountain, the story of three generations of babusha forest farm, represented by "six old men", continues to this day. "We should continue to carry forward the contemporary Yugong spirit of the 'six old men', carry forward their enterprising spirit of not bowing their heads in the face of difficulties and daring to turn the desert into an oasis, make unremitting efforts, make new contributions for a long time, and make the green Great Wall indestructible." It is an inevitable requirement for greening to deeply grasp the laws of nature. In November 2013, he first proposed the concept that "mountains, rivers, forests, fields and lakes are a community of life", and then incorporated "grass" into it. Grassland is an important terrestrial ecosystem in China. 80% of the water of the Yellow River and 30% of the water of the Yangtze River come from grassland areas. For a long time, most grasslands in China have been degraded to varying degrees due to excessive demand for grasslands, less investment, overload and overgrazing, and climate change. In 2018, the party and state institutions reformed and established the State Forestry and grassland administration. In March 2021, the general office of the State Council issued several opinions on strengthening grassland protection and restoration to promote grassland ecological restoration. Through unremitting efforts, the continuous deterioration of grassland ecology in China has been initially curbed. At the end of the 13th five year plan, the comprehensive vegetation coverage of grassland reached 56.1%. "As a whole, we should add the word 'sand' here to manage the system of mountains, rivers, forests, fields, lakes, grass and sand." The scientific concept of continuous deepening and expansion has become an important guide for land greening and ecological civilization construction in the new era. Under the warm spring sun, the Yani wetland at the intersection of the Yarlung Zangbo River and the Niyang River is full of waves, and black necked cranes and spotted headed geese fly by from time to time. Turn the clock back to July 2021—— Known as the "third pole of the earth" and "Asian water tower", the Qinghai Tibet Plateau is an important ecological security barrier for China and even Asia. Today, about 80% of Tibet's land area is prohibited or restricted from development. Farmers and herdsmen have become wild Rangers, forest rangers and wetland protectors, and become "ecological guards" of the snowy plateau. The ecology of the snowy plateau is improving year by year. Planting green means planting happiness for people's livelihood—— The green heart Forest Park in Tongzhou City, Beijing, is full of new green and vitality, and the Millennium grand canal winds and flows. In the tree planting area of the park, a Purple Magnolia is in bud. "The environment has changed greatly!" Zhang Hongfeng, a citizen living nearby, said that in the 1990s, there were three large villages close to Dongfang Chemical Plant and some "scattered pollution" enterprises. At that time, the air was bad and the canal water was once polluted. After 2018, we began to vacate the chemical plant and prepare for the construction of green heart park, and everything gradually got better. Planting green before building a city is a new concept for the construction of xiong'an new area. On November 13, 2017, the first tree and forest of "Millennium show forest" took root in plot 9. He looked at the swaying young trees and said happily, "green water and green mountains are Jinshan and Yinshan. Xiongan new area depends on such an ecological environment to reflect its value and increase its attraction." Live up to the expectations of the general secretary: with the appearance of xiongan country park with a total area of about 18 square kilometers, the forest coverage rate of the new area has exceeded 30%. To plant green for the people, we should not only have a magnificent freehand brushwork, but also work hard on embroidery. In recent years, exquisite corner parks and lush and fresh landscape forests have replaced the disorderly and illegal buildings in the past, and the citizens of the capital feel more comfortable breathing in the "ecological blank". In Shanghai, small and micro green spaces and "pocket parks" appear around citizens. Use "leftover materials" to insert green at the seams and "make a Taoist temple in the shell of a snail". It can not be more vivid to describe the "thousand garden project" in Shanghai that tries every means to create green for the people. In the 1990s, the per capita area of public green space in Shanghai was only about 1.11 square meters, slightly larger than a newspaper. The latest data show that the per capita public green space area of the city has increased to "one room" of 8.5 square meters. Planting green also breeds development opportunities——
