摘　　要：拐棍竹是卧龙国家级自然保护区内大熊猫的主要食物之一。对卧龙三个区域内拐棍竹笋的生长发育研究表明,无论是新笋出土时间(10 cm)、还是到达大熊猫可取食高度(30 cm)和停止取食高度(200 cm)的时间,都是随着海拔的升高而有所推迟。各区域之间同海拔高度下的新笋发育也存在显著差异,大熊猫可取食时间长度(停止取食时间-初始取食时间)在各个海拔高度下差异较小。野生大熊猫在水平方向上的移动能增加对竹笋的选择机会,而通过垂直迁移可以延长取食竹笋的时间。卧龙自然保护区拐棍竹新笋的整体存活率为48.64±8.43%。山体中部(2 000m—2 300m)的新笋基径较粗,之后会随着海拔升高逐渐减小。Fargesia robusta is one of the most important foods for the giant panda. The research for the shoots inthree areas of Wolong Nature Reserve showed that time of the n e w shoot for sprouting （ 10 cm ） , initial feeding （30cm ） and finishing feeding（200cm ） by the giant panda would delay with the elevation increasing. The difference was also significant in different areas at the same elevation. The period of the giant panda feeding to the shoots （time of finishing feeding-time of initial feeding） had little difference in different elevations. Giant pandas had more chances to choose shoots via wandering at horizontal direction, and had longer period to fetch shoots via Vertical m i-grations. Survival rates of the shoots were 48. 64 ± 8. 43 % , the basal diameter was the biggest at middle part （2 000-2 300m ） of all areas, and then decreased with the increase of the elevation.
