June 17 this year is the 25th World Day to Combat Desertification and Drought. The theme of China's publicity is "Combat Land Desertification, Promote Green Development", which aims to implement Xi Jinping's thought of ecological civilization, practice the concept of green development, gather social consensus, create a strong atmosphere for the whole society to participate in combating desertification, and jointly build a beautiful earth home.

　　Desertification is a major ecological problem facing the world. China is the country with the largest area of desertification in the world, the largest population affected and the heaviest wind and sand hazard. Since the founding of New China, the Party Central Committee and the State Council have attached great importance to the prevention and control of desertification, made the prevention and control of desertification an important strategic task, taken a series of effective measures to promote it, and successfully curbed the expansion of desertification. The national desertification land area has changed from an average annual expansion of 10,400 square kilometers at the end of the last century to an average annual reduction of 2,424 square kilometers at present, and the sandy land area has changed from an average annual expansion of 3,436 square kilometers at the end of the last century to an average annual reduction of 1,980 square kilometers at present, realizing the change from "sand in and people out" to "green in and sand out". It has achieved the historic transformation from "sand into people retreating" to "green into sand retreating", sustained economic development and improvement of people's livelihood in sandy areas, and achieved the goal of zero growth of land degradation by 2030 proposed by the United Nations ahead of schedule. The successful practice of desertification control in new China has not only created a road combining the management of desert ecosystems with Chinese characteristics and improvement of people's livelihood, but also shaped the spirit of sand control with perseverance and perseverance, injected a powerful impetus to promote the construction of ecological civilization and green development, and contributed "Chinese experience" and "Chinese wisdom" to global ecological governance. "Chinese wisdom" for global ecological governance, has won wide praise from the international community.

　　Green is related to human welfare and global future. Building a beautiful home is the common dream of mankind. President Xi Jinping stressed at the opening ceremony of the 2019 World Horticultural Expo in Beijing, China, that the Earth is the only home on which all human beings depend for survival. We should protect the ecological environment like our own eyes, treat the ecological environment like life, build the foundation of ecological civilization together, and take the road of green development together. At present, China's ecological civilization construction in full swing, the economy from the high-speed growth stage to high-quality development stage, the development of the economy, the task of improving the ecology is very heavy. Overall, China is still lack of forests and less green, ecological fragility, desertification land area of 2,611,600 square kilometers, accounting for 1/4 of the national land area; sandy land area of 1,721,200 square kilometers, accounting for nearly 1/5 of the national land area. nearly 40% of the country's poor counties, nearly 25% of the poor population is distributed in the northwest sandy areas. Land desertification has become an important constraint in building ecological civilization and beautiful China, we must strengthen the problem-oriented, adhere to long-term efforts, and continuously promote the cause of desertification control to achieve new results.

　　Land desertification is caused by various factors such as climate change and unreasonable human economic activities, and is the result of the combined effect of human and natural factors. To combat land desertification, we must take Xi Jinping's thought of ecological civilization as our guide, consciously practice the concept of green water and green mountains is the silver mountain of gold, strictly follow the inherent mechanism and laws of the ecosystem, combine natural restoration and artificial management, coordinate the system management of mountains, water, forests, fields, lakes and grasses, adhere to local conditions and classify policies, comprehensively accelerate the pace of desertification prevention and control, and create a diversified and symbiotic desert ecosystem.

　　A comprehensive protection. Protecting the natural vegetation in the sand area is the first priority to combat desertification. To adhere to the ecological priority, protection priority, natural restoration is the main, the full implementation of the desert ecological protection red line, the source of large rivers, wind and sand source areas, grassland degradation of sandy key areas to implement strict sandy land closure protection measures, and gradually the sand area natural ecosystem comprehensive protection, promote natural vegetation rest and recuperation. In-depth implementation of the "sand control law", the full implementation of the sand control target responsibility assessment rewards and punishments, sandy land sealing protection and repair system, crack down on deforestation in the sand area, illegal mining and construction activities, the destruction of the sand area vegetation and ecological crime "zero tolerance", increase the investigation and punishment, and effectively protect every inch of the sand area. Green.

　　Second, scientific governance. Desertification management must follow the laws of nature, adhere to the use of scientific and technological means, so that the natural evolutionary process in a benign direction. Adhere to the local system, appropriate forest, irrigation, irrigation, grass, grass, wilderness, wilderness. In-depth implementation of the integrated ecological protection and restoration of landscape, forest, field, lake and grass, agriculture, forestry and water multi-pronged, integrated management. Based on the actual sand area, vigorously develop rain-fed forestry, water-saving forestry, adhere to the water to determine the forest, water to determine the green. Science to create forest and grass vegetation, vigorously promote the combination of trees, irrigation and grass, mixed afforestation, low-coverage sand control and other models, and strive to enhance the science of desertification control, diversity.

　　Third, green people. Green development must have ecological resources for support, the sand area of forest and grass resources is both the ecological base, but also the source of wealth. Sand control to deeply practice the concept of green development, take the initiative to assume the ecological benefit, ecological benefit to the people, ecological rich people's historical mission, and actively explore a new path of ecological priority, green development-oriented high-quality development. Make full use of the sand area light and heat resources, diverse species resources, land resources and other advantages, and actively develop to irrigation grass fodder, Chinese herbal medicine, economic forestry and fruit as the focus of the sand area special planting industry, deep processing industry, as well as biomass energy, desert tourism and other green industries, so that the people in the sand area to get rich in the sand, in the rich in the sand, and promote sand treatment and forestry to benefit the people.

　　Fourth, all people should participate. Many years of practice has proved that the greatest power of desertification control lies in the creation and dedication of the people. Must mobilize the masses to participate in desertification control, and promote large-scale greening action. Adhere to the "construction of everyone to participate, the results of everyone to share", all rely on the masses, all for the masses. Actively build a platform, provide services, explore mechanisms, mobilize all positive factors to participate in desertification control, and build an ecological governance system with the participation of the whole society. Increase the spirit of sand control, typical figures and deeds of publicity, social cohesion love green planting green protection, so that respect for nature, love nature's ecological values and green ideas into the hearts of people.

　　Five to global governance. In the face of ecological challenges, mankind is a community of destiny, a loss and prosperity. Only by working together can we effectively respond to climate change, promote global ecological governance, and maintain global ecological security. We must actively implement international conventions, take the initiative to participate in international rule-making, and promote the improvement of the global ecological governance system. Make full use of international and domestic "two kinds of funds and two technologies", insist on "importing and going out", learn and share various advanced technologies and governance models, promote the governance of sand sources in countries along the Silk Road Economic Belt and neighboring countries, strengthen exchanges and cooperation with Africa and Arab countries We will strengthen exchanges and cooperation with African and Arab countries on desertification control, build a green Silk Road, create new highlights of cooperation, and promote the common development of global desertification control.
