  • According to the data of Beijing-Tianjin-Hebei region in 2020, the carbon release and oxygen consumption, and carbon fixation and oxygen release in 2020 were calculated, and the carbon release and oxygen consumption, carbon fixation and oxygen release, as well as the demand area of ecological land in 2025 were calculated. The results showed that the carbon release and oxygen consumption in Beijing-Tianjin-Hebei region in 2020 were 125.5761 million tons and 143.5337 million tons, respectively, and in 2025, they would be 135.957 0 million tons and 163.392 0 million tons. In 2025, the required standard ecological land area to maintain carbon balance in Beijing-Tianjin-Hebei region was smaller than the existing standard ecological land area, indicating that there was no need to increase the area. However, from the perspective of different provinces, the ecological land area of Beijing and Hebei could meet the needs of carbon and oxygen balance, but Tianjin should increase the standard ecological land to meet the needs of maintaining carbon and oxygen balance in the city. In the process of actual social and economic development, the area of ecological land would be slightly adjusted, and the structure and quality of ecological land would also change. Therefore, in actual production and scientific research, it should be gradually corrected according to the actual annual change of ecological land.
