Indices of temperature, precipitation and relative evapotranspiration (RET) for the last 51 years in the borderland between Shaanxi and Gansu Provinces, and Ningxia Hui Autonomous Region (BSGNAR) were calculated to analyze the climate change in this area. During the past 50 years, the average temperature increased significantly, while precipitation decreased slightly with regional differences. RET change was not so distinct in general, but had a minor increase at the late stage of the study period. Under such circumstances, climate change had clear effects on distribution of potential vegetation in the area, with a tendency to transit to warming and drying vegetation types.

Key words: borderland between Shaanxi-Gansu-Ningxia, climate change, relationship between climate and vegetation.
