Abstract: The spatial distribution patterns, stand density, and stand age structure of a Picea crassifolia forest in Qilian Mountain were investigated, and the tree-ring was also measured. All the data were used to reconstruct its disturbance history and restoration via geostatistical methods. The results showed that Picea crassifolia forest density exponentially increased from 256 individual•hm^-2 to 16 966 individual•hm^-2 during the 30 years after logging disturbance ( y=237 e^0.14x, R²=0.97 ). There was no any other tree species appeared during this restoration process, suggesting that logging disturbance created no opportunities for other tree species successfully invading into the study area. Further analysis of the tree-ring data showed that logging disturbance controlled tree growth at the scale of 9～20 years, while precipitation and temperature were the main control factors for the tree growth at the scale of 26～45 years.
