On the 15th, the reporter learned from the Ministry of Natural Resources that the "China Ecological Protection Red Line Blue Book (2023)" (hereinafter referred to as the "Blue Book") organized and compiled by the China National Land Survey and Planning Institute was first presented to the public on that day. On August 15th, the first National Ecological Day home event was held in Huzhou, Zhejiang. The National Development and Reform Commission of China, the Ministry of Natural Resources of China, and other departments released important achievements for the third anniversary of carbon peak and carbon neutrality, as well as the "China Ecological Protection Red Line Blue Book (2023)" and other achievements. The picture shows the release of the "China Ecological Protection Red Line Blue Book (2023)". Reported by Qian Chenfei, a journalist from China News Agency, August 15, 2023 is China's first National Ecological Day. The ecological protection red line is a representative achievement and significant institutional innovation in the construction of ecological civilization. The Ministry of Natural Resources, in conjunction with the preparation of the National Land and Space Planning Outline (2021-2035) and other departments such as the Ministry of Ecology and Environment and the National Forestry and Grassland Administration, has fully completed the delineation of the national land and sea ecological protection red line for the first time, achieving a red line to control important ecological spaces and providing a Chinese plan for global ecological protection and governance. The total ecological protection red line area designated in this plan is about 3.19 million square kilometers, of which the land ecological protection red line area is about 3.04 million square kilometers (accounting for more than 30% of China's land area), and the marine ecological protection red line area is about 150000 square kilometers. Through the demarcation of ecological protection red line, the most important natural ecosystem, the most unique natural landscape, the most essence of natural heritage, and the most abundant biodiversity in China have been completely protected, realizing the large-scale and overall protection of important natural resources, ecological space, rare and endangered species and habitats, leaving precious natural assets and beautiful homes with beautiful mountains and rivers for future generations. This is China's first ecological protection red line blue book, which systematically summarizes the process, methods, achievements, and practical cases of fully completing the delineation of ecological protection red lines. It proposes ideas and suggestions to strengthen the supervision of ecological protection red lines and improve the ecological protection red line system. According to reports, the delineation of ecological protection red lines should adhere to the "six principles": firstly, adhere to the system concept, stand at the height of harmonious coexistence between humans and nature, coordinate development and security, and based on national spatial planning, regard the ecological, agricultural, urban and ecological protection red lines, permanent basic farmland protection red lines, and urban development boundaries as the insurmountable red lines for adjusting economic structure, planning industrial development, and promoting urbanization, Promote the green and low-carbon transformation of development methods, and accelerate the formation of green production methods and lifestyles. Secondly, we must adhere to the bottom line thinking and firmly establish the concept that mountains, rivers, forests, fields, lakes, grasslands, and sands are a community of life. Based on the evaluation of resource and environmental carrying capacity and the suitability of national spatial development, we will classify areas with extremely important ecological functions, fragile ecology, and potentially important ecological value as ecological protection red lines, including integrated and optimized natural reserves. We will firmly uphold the national ecological security bottom line and build a strong national ecological security barrier, Accelerate the formation of a spatial pattern that saves resources and protects the environment. The third is to adhere to people-oriented principles, focus on the organic integration of production, life, and ecology, and strengthen the integration of densely populated urban agglomerations and metropolitan areas
