Abstract Desert-grassland vegetation productivity is significantly influenced by precipitation change, at either annual or seasonal scale, in arid and semi-arid region. In the period of 1971 to 2011, the maximum annual precipitation is 3.76 times of the minimum in the desert-grassland transitional region northern to Yinshan Mountain rightly at the northern part of Inner Mongolia of China. Vector precipitation is more significantly related to vegetation productivity (R=0.920, R0.001=0.801)compared to long term annual precipitation and actual annual precipitation influence. Influence of the monthly accumulative precipitation on the productivity of grass and semi-bush dominated vegetation is more evident in the growing season and the influence in the period of June to August is the most significant.
