Abstract: Meteorological data of fifty observation stations from 1961 to 2006 were analyzed. Based on the principles of advanced comprehensive and sequential classification, the first grade grasslands of Qinghai, were classified into 11 classes, which agreed with the features of Qinghai grasslands. This showed that it was feasible to classify Qinghai grasslands and three typical regions were chosen to analyse their trends, K value (wetness degree), accumulated temperature over 0℃, and grassland succession.
