Located in the eastern part of the Eurasian steppe, the wind-blown sandland regions in north China are one of the most fragile ecosystem types. These ecosystems play strategically important roles in the construction of eco-security shelters and the Silk Road Economic Belt. Supported by a series of ecological conservation projects, the ecological environments in the region have greatly improved. However, because of ever-increasing anthropogenic disturbances and global climate change, this region is still facing serious environmental pressures. Under the support of a project entitled "Integration and Application of Ecological Restoration Technology in Key Fragile Ecoregions", we carried out research on the causes of land desertification and the spatial distribution of the degraded lands. By doing this, we integrated techniques and methods for ecological restoration in these fragile areas. This project is part of the Science and Technology Service Network Initiative Project of the Chinese Academy of Sciences. We implemented engineering practices for ecological restoration in the north of the Yinshan Mountains, Hunshandake Sandy Land, and the Kerqin Sandy Land. These practices included establishment of artificial pastures, adaptive management of natural grassland, and restoration of the degraded grasslands. By monitoring and assessing these practices, we identified and parameterized various models and techniques for the ecological restoration of desertified grassland in each of these regions. This research will promote the application of these techniques in the wind-blown sandland regions of North China. It will also provide a scientific basis for decision-making by the central and local governments to formulate ecosystem management and restoration policies, and provide technical guidance for the ecological restoration industry. These findings will also provide important information for relevant future research in this area.
