The promotion of ecosystem carbon storage and sequestration play an important role in achieving carbon peak and carbon neutrality goals. Ecological protection and restoration have profound effects on carbon sequestration in ecosystems. During 2016 to 2019, the related ministries have arranged a total of 35 projects, including three batches of ecological protection and restoration pilot projects and the first batch of integrated protection and restoration projects, across 27 provinces. We analyzed the spatial pattern of ecological protection and restoration projects and its effects on the ecosystem carbon sequestration capacity, and identified the important and sensitive areas of ecosystem carbon sequestration. Considering ecological protection and restoration areas that were highly concerned by the nation, and distribution of major projects for the protection and restoration of important national ecosystems, we explored the priority area and technical strategies of integrated protection and restoration projects of full-array ecosystems under carbon peak and carbon neutrality goals. We found that the changes of ecosystem carbon sequestration in the zone of 25 pilot projects varied with regions. The priority areas were mainly distributed on the Qinghai-Tibet Plateau ecological barrier area, the northern sand prevention belt, the key ecological areas along the Yangtze River, and hilly area in South China where mostly covered by forest, plateau grasslands, deserts, karst areas etc. Accordingly, we proposed technical strategies for the restoration projects in different regions. In forest ecosystem areas, we should not only improve coverage and quality of forest, but also strengthen biodiversity protection and soil carbon sink capacity. In plateau grassland and frozen soil areas, the monitoring of grassland degradation and frozen soil are essential to improve the land quality. In the desertification area of Northwest China, we should focus more on the research of carbon sink theory and technology. In karst areas, the dual carbon sink effect is the key factor which should be taken seriously. The incremental improvement of carbon sinks for different ecosystems according to local conditions will not only help achieve the dual-carbon goal, but also help improve the benefits of ecological protection and restoration projects.
