Abstract: Pre-released training can help the enclosed animals to survive in the wild,and therefore making the pre-released giant panda have their own home range is one of the most important aims of the training.After more than 2 years of pre-released training,it was found that "Xiang-Xiang" had three marked behaviors,and persistent period had no significant difference,but the every marking time was significantly different.Man-made food had impacts on the home range of the pre-released giant panda,it would enlarge its home range after stopping the man-made food,and would spend more time and more place to forage during shooting period in the bamboo forest.Decreasing or stopping man-made food might help the pre-released giant panda to train in the wild,and mother giant pandas might help cubs to learn living skills in the wild quickly.
