Abstract: Previous studies on vegetation change have difficulties to depict the detail information of dynamic character- istics of vegetation disturbance and recovery. This study takes Daliuta as a research area to extract the year of event on- set,the duration and magnitude of vegetation disturbance and recovery based on time trajectory segmentation algo- rithm. The results indicated that:① At different production functional ozone scales,the area proportion of each time of event onset showed clustering over the year,large disturbance and recovery both distributed in all functional zones in 1995,and the same as partial functional zones including mining face ozone,small coal pit area and vegetation recon- struction area in 2010. Large disturbance and recovery of open-pit mining in 2006 and 2009 respectively was occurred. Compared with other functional ozone,the industrial square and built-up area were seriously disturbed and recovered. The disturbance magnitude of coal pit was significantly higher than the magnitude of recovery,and the differences be- tween disturbance and recovery magnitude were largest among different functional zones. ② At mining face scale,the vegetation response to coal mining showed postponing. In addition,the largest range of disturbance occurred in the sec- ond year after exploitation. The magnitude of first vegetation disturbance after coal exploitation was higher than recov- ery magnitude,whereas the disturbance duration was less than the recovery duration. The range of duration of the first disturbance after coal exploitation is from 1. 54 to 2. 40,while is from 4. 05 to 6. 75 for the first recovery duration after coal mining.
