Led by Prof. Liang Cunzhu from Inner Mongolia University, this project was carried out in collaboration with Institute of Botany, Chinese Academy of Sciences, Beijing Normal University, Inner Mongolia Agricultural University, Ningxia University, Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, Inner Mongolia Mengcao Eco-Environment (Group) Co., LTD., Institute of Agricultural Environment and Sustainable Development, Chinese Academy of Agricultural Sciences and other units. In view of the serious degradation of grassland in northern China, the ecological security and the weakening of grassland production function, and the underdeveloped ecological animal husbandry and ecological industry, the comprehensive management technology and policy of desertification and degraded grassland are developed and demonstrated. Through the restoration and sustainable utilization of degraded grassland, the win-win or all-win situation of environment improvement and people's prosperity is achieved. The topic takes steppe, desert steppe and natural grassland in central and western Inner Mongolia as the main research area, takes desertification grassland degradation mechanism and ecosystem service assessment as the basis, focuses on degraded grassland restoration, ecological animal husbandry and grass industry development technology research and development and demonstration, and takes ecological industry technology integration and demonstration as the main innovation. Technology demonstration and technology extension as the main results of the transformation mechanism of the project research. A total of 32 datasets have been released in this project, including data on regional climate, vegetation, soil and grazing experiments of desertification grassland in Inner Mongolia, Gansu and Ningxia. Technology systems suitable for service evaluation of different degraded grassland ecosystems have been developed, and service functions such as productivity, carbon storage, windbreak and sand fixation, and tourism of grassland ecosystems at different degraded levels have been systematically evaluated. To provide an evaluation system for the graded management and sustainable use of degraded grassland. This research not only has important theoretical significance, but also has important application prospect.
