The facing key limited facts for rangeland are introduced，which the relative information was collected from the national key program and the international program conducted in northern China. Ecological issues surrounding rangeland resources, water supply, grassland degradation and forage productivity are indented to be the most critical issues. As a demonstration sample，Xilingole grassland area is exhibited to sum up the technology system for vegetation recovery and grassland improvement. A series of strangers are suggested to improve grassland management and to increase the grassland management effect., authors=null, authorsList=null, authorCompany=null, correspAuthors=null,
