Landuses and spatial landscape patterns of Qinghai Province in the Yellow River Basin in the year of 2001 are analyzed based on the technology of GIS and RS and using software of FRAGSTAT.An index of landscape resilience is further proposed to analyze the stability of landscape ecosy stem in the studied region.Results obtained show that the studied region is mainly covered with grassland, and it's landscape is complex and unstable, but has no obvious fragmentation.The diversity and landscape resilience indices of the headwaters of the Yellow River are lower than those of other counties, w hereas the diversity, equality and landscape resilience indices of the main stream of the Yellow River are higher than those of other counties in the studied region.In addition, the fragmentation of Xi' ning City is higher, whereas the landscape resilience index is lower than that of other counties in the studied regions, indicating that the Xining City meets with relative higher human disturbance than others.
